Silica
fumed nanoparticles were dispersed in polyacrylamide thin
films by direct mixing. Atomic Force Microscopy study was
carried out in order to analyze the surface roughness.
Height distribution of surface roughness changes from
Gaussian like for polyacrylamide to skew asymmetric when
increasing the silica concentration. The length of the
distribution tail increases, indicating the formation of
multi-scale features that increase in number and size, as
the silica increase.
Key
words: Polyacrylamide, nanocompsite, surface roughness,
AFM. |
