Abstract:
In order to obtain nano-hole super heat insulating composite materials, with silane coupl-ing agent on the in-situ nmSiO2 surface treatment, the core-shell structure composite materials are prepared by dispersion polymerization process of polystyrene grafted on the nano SiO2 par-ticles. By TEM on these samples,the impact of the system components,initiator,polymerization parameters and dispersion process is discussed. The results show that the system component of the greatest impact on conversion rate is the radio of SiO2 aerogels/St, with organic initiator AIBN as initiator, after a unique ultrasound technique the core-shell composite materials structure with 70% coating can be obtained. 2 tabs, 3 figs, 9 refs.
