Character and Preparation of Nano-SiO₂/PI Composites by Sol-Gel Method

Abstract:

Polyimide/nano-SiO₂ (PI/SiO₂) composites with different contents of SiO₂ were prepared by in situ polymerization. The transmittance, solubility, thermal property, flame retardant properties and mechanics properties of PI/nano-SiO₂ composites were investigated. The results showed that with the increased addition of SiO₂ content, the transmittance of PI/SiO₂ compositions reduced; tensile strength changed with the amount of nanometer powder, when the addition content was 10 wt%, it achieve the maximum value. Thermal resistance of the composite was improved obviously while with the amount of nanometer powder increased, volume resistivity coefficient of volume resistance would have decreased.
