With the transparent biaxial orientation polyproplene graft N-vinyl-2-pyrrolidone (BOPP-g-NVP) as samples , the complexation of the surface grafted NVP functional groups with iodine was investigated , and the effects of proportion , temperature and time on complex reaction were studied. The results show that increasing
the complex proportion and rasing complex temperature and extending reaction time are favourable to raise the complex reaction degree. Then , the disinfection of PP-g-NVP-I was evaluated using“disinfectant cloth”prepared by polypropylene non-woven-g-NVP with iodine complexation. It is found that the“disinfectant cloth” has disinfectant and inhibition action to the bacillus and candia albicans evidently.
