The morphology
of the materials was observed by scanning electron microscope
(SEM) after gold coating using SEM-JEOL, JSM-
5600 model operated at an accelerating voltage of 20 kV.
The surface topology of the fractured surface was investigated
by means of atomic force microscopy (AFM) Seiko
SPI3800N, series SPA-400 (Tokyo, Japan). High resolution
transmission electron microscopic (HR-TEM) images
were recorded using JOEL, JEM 2100 electron microscope
operated at 200 kV. The surface roughness of the
samples was analyzed. X-ray diffraction (XRD) patterns
were recorded for nanocomposites having varied POSS
percentages at room temperature by monitoring the diffraction
angle 2h from 10 to 90 on a Rich Seifert (Model
3000) X-ray powder diffractometer. The diffractometer
was equipped with a Copper target (k 1.5405 A) radiation
using Guinier type camera used as focusing geometry
and a solid state detector. Curved nickel crystal was used
as the monochromator.
