Description
Summary:The Synthesis of a self-cleaning carpet is conducted by coating chitosan-titania nanocomposite on a synthetic carpet. The nanocomposite is synthesized by adding 3wt% chitosan to TiO2 by means of wet impregnation method. The nanocomposite is then characterized by FTIR to determine the bonds that occur, UV-Vis DRS to determine the energy bandgap, and SEM-EDX to analyze the morphology and composition. The synthesized nanocomposite is then coated on the carpet using varied tetraethyl orthosilicate (TEOS) additions. Two tests are done to the carpet, namely the self-cleaning test by dipping the carpet into mud suspension and photodegradation test by dipping the carpet into a stirring methylene blue solution. The FTIR characterization result shows that a number of bonds occured between chitosan and TiO2, while UV-Vis DRS shows that the synthesized nanocomposite has a bandgap value of 3.11 eV. The self-cleaning of mud test and the methylene blue photodegradation test show that the addition of 0.67v% TEOS is the most optimum addition in the nanocomposite coating on the carpet surface.
