| Abstract: | Through oxidization modification of starch,the relative performance of decontamination coating based on PVA was studied by raring the amount of oxidized starch.IR spectrum of oxidized smrch showed that the carboxyl absorption peak appeared at 1733cm~(-1).Stability time of decontamination fluid of 10%oxidized starch was up to 1673 h,tensile strength was 29.32 MPa and elongation at break was 238%.The light transmittance of decontamination coating was up to 85%and the decontamination average efficiency was inore than 80% for different materials. |
