Abstract
The solution behaviour of polymer/silica hybrid nanocomposites was investigated using a Brookfield viscometer. The nanocomposites were prepared using the sol-gel technique with tetraethoxysilane as the precursor for silica. This paper is divided into two parts: the first part deals with the measurement of the solution viscosity of acrylic rubber/silica, epoxidised NR/silica and PVA/silica nanocomposites at room temperature (30 degrees C) at intervals of 24 h for 5 days. The second part of the paper reports on a detailed investigation of the solution behaviour of PVA/silica nanocomposites, as it registered the biggest rise in viscosity with time after 5 days of study. 22 refs.
