【 摘 要 】

The aim of this study was to investigate the dependence of elastic modulus on component's proportion of nanoparticles containing PVA/PVAc blend composites by means of response surface methodology. Full factorial design method was used to perform a series of experiment. The statistical analysis of experimental results showed that adding of nanoparticles to the PVA/PVAc compositions has substantial effect on the tensile properties. The higher values of the tensile elastic modulus show systems with almost equal content of polymers in the blend. Regardless of PVA/PVAc content relationships, the higher modulus values present systems that contain both nanoparticles. Composition, which provide greatest value of elastic modulus was determined and experimentally verified.
