Abstract
A simple method is adopted to prepare conducting polyaniline thin film on cellulose filter paper by chemical oxidative polymerization. In order to improve the adhesion of polyaniline on cellulose nanofiber aniline terminal, silane monolayer was used as catalyst to initiate polymerization reaction. It was also showed that aniline dimer modified cellulose nanofiber shows an enhanced polyaniline growth and acting as seed for the polyaniline growth. The polyaniline modified cellulose fibre filter paper was then characterized with UV-visible spectroscopy, FT-IR, FE-SEM and electrochemical studies. Polyaniline modified filter paper strips can be used for naked eye sensing of ammonia and hydrazine in environmental samples
