Study on Temperature and Time Affecting the Dispersity of Nano-Silica in Organic Solvents

摘要

Surface modification improving the dispersity of the prepared nano-silica in organic solvents using different temperature and time were investigated. The result suggested that the optimum modification condition was that temperature was 80 °C and time was 1.5 h. The dibutyl phthalate absorption number of the optimum modified nano-silica was 3.5 cm~3/g.
