摘要: Atomic force microscopy(AFM)is used for the morphology study of polyvinyl alcohol/silica(PVA/SiO2)nanocomposites prepared by incorporating solution compounding and self-assembly technique.The results show that the strong particle-particle interaction of SiO2 nanoparticles is greatly suppressed,and the SiO2 nano-particles are homogenously distributed in PVA matrix as spheric nano-clusters.The average size of the SiO2 nano-clusters is below 50 nm at low SiO2 loadings(<=5 wt%).At higher SiO2 contents,the particle aggregations can be clearly observed,and the average size of SiO2 aggregates significantly reach up to 110 nm and 250 nm at SiO2 content of 10 wt% and 15 wt%,respectively.AFM height profiles demonstrate that the surface heterogeneity of the nanocomposite is governed by the SiO2 contents.The surface roughness evaluated as root mean square(RSM)of peak-to-valley height values shows that the surface becomes rougher as the SiO2 content increases,particularly,a remarkable increase in surface roughness is found at the SiO2 content of 10 wt%.
