  Abstract

We developed a highly hydrophobic, UV-protective, and self-cleaning cotton fabric by incorporating graphene oxide (GO) nanosheets and poly(glycidyl methacrylate) nanoparticles (PGMA NPs). The GO was synthesized using a modified Hummer's method, while the PGMA NPs were synthesized via dispersion polymerization. Crosslinking agents with isocyanate groups were employed to enhance the adhesion between the GO and cotton textiles. The hydroxyl groups on GO interacted with the glycidyl-functionalized PGMA NPs, further improving the fabric's properties. The cotton fabric's nano pattern increased its structural hydrophobicity and prevented air from reaching the material surface. The application of octadecyl thiol (ODT) further enhanced the fabric's hydrophobicity and reduced surface energy. To characterize the nanomaterials and coated textiles, various techniques such as X-ray diffraction, UV–visible spectroscopy, Fourier-transform infrared spectroscopy, scanning and transmission electron microscopy, energy-dispersive spectroscopy, and thermogravimetric analysis were employed to analyze their chemical composition, functionalization, surface area, and morphology. The size of the GO nanosheets was approximately 500 nm, while the PGMA NPs had a size of around 60 nm. The coated fabric samples demonstrated a hydrophobicity angle of approximately 140° ± 1, indicating high water repellency, self-cleaning effect and exhibited outstanding UV protection.
