Abstract
Organic/inorganic hybrid composites that utilize polymers as a matrix have been recognized as one of new class advanced materials, because they can take benefit by combining the merits of both inorganic materials (rigidity and thermal stability) and organic polymers (flexibility, ductility, and processability). In terms of inorganic materials for hybrid composites, silica has been widely used owing to its low dielectric property and high thermal stability which are of importance for microelectronic applications.
Polyamide-imide(PAI) is a kind of thermoplastic resin, has good high-temperature resistance, outstanding mechanical properties and excellent oxidative stability, all of which have led PAI to have been widely used with electronic materials, adhesives, composite materials, fiber, and film material. Silica nanoparticles as a very important inorganic material have emerged as an area of intense current interest motivated because of their special physical and chemical properties, such as their small size, strong surface energy, high scattered performance, and thermal resistance.
In this study, the functional PAI-Colloidal silica nano hybrid material were prepared via simple blending. 7nm, 12nm, 20nm, 40nm silica
nanoparticles were well dispersed in the PAI matrix with alkoxy silane, and the amount of silica nanoparticles to PAI was investigated to be from 10 wt%. The PAI-Colloidal silica nano hybrid material were made via sol-gel process of the mixture of organo silane. The PAI-Colloidal silica nano hybrid material were characterized by Fourier transform infrared(FT-IR) spectra, scanning electron microscope(SEM), thermo gravimetric analysis(TGA).
