AbstrakTelah dilakukan penelitian pelapisan komposit nanosized Chitosan/TiO 2 pada permukaan kain katun dan uji kinerja fotodegradasinya terhadap zat warna Rhodamine B. Pelapisan komposit nanosized Chitosan/TiO 2 ke permukaan kain katun menggunakan metode dip-coating dengan teknik pad-dry-cure. Kain katun yang telah terlapisi komposit nanosized Chitosan/TiO 2 dikarakterisasi dengan Scanning Electron Microscope (SEM), X-Ray Diffraction (XRD) dan Fourier Transform Infrared (FTIR). Kain terlapisi komposit nanosized Chitosan/TiO 2 dilakukan uji fotodegradasi terhadap Rhodamine B dibawah paparan sinar UV dan sinar matahari. Penelitian menyimpulkan bahwa kain katun terlapisi komposit nanosized Chitosan/TiO 2 dapat mendegradasi zat warna Rhodamine B di mana dengan penyinaran sinar UV lebih efektif dibandingkan dengan sinar matahari. AbstractThe coating of nanosized Chitosan/TiO 2 composit on cotton fabrics substrate and its performance for dye of Rhodamine B was studied. Nanosized Chitosan/TiO 2 composit coated on cotton fabrics was done by dip-coating method through pad-dry-cure technic. Cotton fabric thats was coated by nanosized Chitosan/TiO 2 composit was characterized by SEM, XRD, and FTIR. Photodegradation Performance test of cotton fabric coated Nanosized Chitosan/TiO 2 composit for dye of Rhodamine B was done under UV ray and sun ray. It was concluded that was cotton fabric coated nanosized Chitosan/TiO 2 can decompose dye of Rhodamine B with UV ray more effective than sun ray.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
