  Abstract

ing one-step methods are employed to generate nanoparticle coating that provides multifunctional characteristics to covered surfaces in terms of antibacterial and superhydrophobic properties utilizing chitosan (CS) biopolymer with fluorochemical as water repellent agent (WRA). Material and process characteristics effect on nanoparticle spreading dispersity, particle dimension, morphology, and functionality are discussed. Relative humidity conditions are also taken as another variant to investigate its impact. Dynamic light scattering method, SEM images, and FESEM images are studied for nanomaterial and coating analyzes. It is found that electrosprayed high water concentrations of solutions tend to show a bigger particle dimension. The increased flow rate of WRA is observed to be in favor of higher WCA values. In addition, elevated relative humidity amounts have an improving influence on the spreading of sprayed particles, achieving higher water repellency and producing smaller particles. The results show that, for single electrospraying, untreated surfaces water repellency was dramatically improved and the mean water contact angle (WCA) increased from 125.4 째 (짹2.3 째) to 142.8 째 (짹3.8 째) and reached 161 째 maximum level. While for coaxial electrospraying, mean WCA was increased to 153.8 째 (짹3.8 째) and, reached 164.8 째 maximum WCA value after 10 min short application time. Up to 99.99 %, antibacterial activity was accomplished for Escherichia coli and Staphylococcus aureus bacteria.
