Nanoparticles have been pivotal in combating viral and bacterial infection diseases due to their high surface area to volume ratio, which allows them to effectively eliminate viruses even at low concentrations. This property is further enhanced as the size of the nanoparticles decreases, attributed to the higher dispersity of the nanoparticles. However, there has been limited research on improving the dispersity and then minimizing the sizes of binary and ternary component nanoparticles, particularly synthesized by incorporating graphene with metal-based nanoparticles including copper (Cu) and silver (Ag), to enhance antiviral and antibacterial properties. To address this issue, we investigate the size control of binary and ternary component nanoparticles, including Cu-graphene, Aggraphene and Cu-Ag-graphene, by altering pH conditions during synthesis. The sizes of resultant nanoparticles are analyzed using transmission electron microscopy (TEM). Our findings indicate that Cu-Ag-graphene nanoparticles, synthesized under reductive conditions (pH 12), exhibit the highest dispersity and the smallest sizes, suggesting they could be highly efficient in antiviral and antibacterial activity.

In this study, inorganic TiO2 photocatalyst and organic guanidinylated chitosan were applied to HDPE fabric as antibacterial agents. Then we used an Ethanol solvent and Microwave curing because HDPE is a hydrophobic fabric and has few reactive sites. Both TiO2-treated and Gu-chitosan-treated samples prepared under optimal conditions showed excellent antibacterial activity of 99.9% against Staphylococcus aureus and Streptococcus pneumoniae. It maintained 99.9% antimicrobial properties after solvent washing. TiO2 photocatalyst has not only antimicrobial function but also self-cleaning function. In order to simultaneously materialize super hydrophobic and photo decomposition of HDPE fabric, hexadecyltrimethoxysilane 5 wt% and photocatalyst 3 wt% were applied. As a result, the contact angle was 152.9 ° showing excellent super hydrophobic properties. In conclusion, HDPE fabrics with excellent antimicrobial function and durability were produced by treating with TiO2 photocatalyst and Gu-Chitosan and then microwave curing. If further study to improve washing durability is conducted in the future, it is expected that the practicality of the fabricated fibers will be higher.

In this study, we investigated the effects of calendaring temperature and drawing process conditions on the physical properties of melt-blown polypropylene (PP) nonwovens. To control the form and physical characteristics of the nonwovens, a laminator was employed for the calendaring process, which enhanced the nonwoven properties through uniform heat and pressure distribution. By adjusting the calendaring temperature and drawing ratios, we manufactured nonwovens with varying thicknesses, fiber diameters, tensile strengths, elongations, and air permeabilities. The tensile strength and elongation of the nonwovens were significantly improved after the calendaring and drawing processes, particularly at higher temperatures and drawing ratios. However, excessive calendaring temperatures led to fiber film formation and structural damage, resulting in decreased tensile strength. Additionally, the density of the nonwovens increased post-processing, reducing air permeability. SEM analysis confirmed increased fiber diameters and some degree of film formation in higher temperature cases. Overall, our findings indicate that selecting appropriate calendaring temperatures and drawing ratios can significantly enhance the tensile strength and elongation of melt-blown nonwovens. These improvements
in mechanical properties can contribute to the production of customized nonwovens
that meet various industrial demands.

Due to the frequent occurrence of abnormal weather phenomena caused by environmental pollution, environmental regulations have been strengthened, increasing the demand for eco-friendly products that limit volatile organic compounds (VOCs) and biocarbon content. This study introduced bio-based polyols to manufacture waterborne polyurethane to address this issue. Waterborne polyurethanes are environmentally friendly resins that do not emit VOCs, as they replace organic solvents with water. This study developed bio-based self-healing waterborne polyurethane using 2-hydroxyethyl disulfide, incorporating disulfide bonds. The resulting polyurethane demonstrated good flexibility (glass transition temperature, Tg, -70.64 oC) and excellent thermal stability (5% weight loss at 280.34 oC). Furthermore, it exhibited eco-friendly characteristics with a biocarbon content of 39%, surpassing the bio-based carbon content regulation of 20-25%. When a crosslinker was applied, the polyurethane achieved a self-healing efficiency of 86.96% and maintained stable peel strength across various flexible substrates.

The effects of radical initiator on the emulsion polymerization using a mainmonomer, such as n-butyl acrylate or cyclohexyl acrylate, and a co-monomer, perfluoro acrylate, were examined. As a radical initiator, 3 kinds of initiator, KPS, AIBN, TBPB were used in the polymerization, then the average molecular weight and PDI value, and the thermal stability of the copolymers synthesized were evaluated by a Gel Permeation Chromatography (GPC) and a Thermogravimetric Analyzer (TGA), respectively. Two types of radical initiator, AIBN and TBPB, exerted higher molecular weight than that of KPS. The PDI values of the copolymers were analyzed by 1.44-5.26 depending on the monomer structure and the ratio of two monomers, and it was also observed that the PDI values showed a proportional relationship on the thermal stability.

As environmental concerns have grown, there is increasing interest in ecofriendly and human-friendly vegan suede as a substitute for natural leather. This study used microfiber vegan suede made from recycled PET and eco-friendly fiber PCT to explore the dyeing of a grey color using disperse dyes, suitable for various products. The results confirmed that the optimal dyeing conditions for grey color on vegan suede are 120 °C for 30 minutes. Additionally, by varying the composition of the reducing agent during the reduction clearing process, it was found that under conditions of 5 g/l of reducing agent, 5 g/l of alkali, and 6 g/l of surfactant, the dry rubbing fastness was rated 4-5, and the wet rubbing fastness was rated 3-4. This represents an improvement of at least one grade in fastness compared to suede without reduction washing, indicating that the reduction washing positively impacts dry rubbing fastness. Ultimately, this study evaluated the influence of the dyeing and reduction washing processes on the fabric's properties, providing foundational data to enhance the practicality of vegan suede.

Polyurethane (PU) stands out as a commercially significant polymer due to its ability to control the various physical and chemical properties and thus its wide range of applications. Recent research has been actively exploring the use of eco-friendly, renewable precursors to replace traditional petroleum-based materials. In this study, an ecofriendly waterborne polyurethane (WPU)-based on aerogels were prepared using castor oil, one of the vegetable oils, as the basic raw material, and water as the main solvent. A stable porous aerogel with a low density of about 0.05 g cm-3 and a thermal decomposition temperature of 223.5 °C was produced using the freeze-drying method. They showed a compression modulus of 0.0231 to 0.547 MPa depending on the ratio of castor oil. Combined with carbon nanotubes (CNT), WPU aerogels exhibited the performance of a pressure sensor with a high sensitivity of 744.53 MPa-1 and a work range of up to 103.3 kPa, demonstrating that they can be used as a high-performance pressure sensor for wearable devices.
