제목 The Transport Properties of PMMA Grafted Silica / 6FDA Based Polyimide Nano composite Film
초록 The surface modified nano silica particle with poly(methylmethacrylate) was fabricated to form a well dispersed nano composite films in the hexafluoroisopropyidene (6FDA) based polyimides matrix. In situ polymerization method was employed to prepare the PMMA grafted silica particle. Since PMMA is miscible with 6FDA based polyimide, silica nano particles could be well dispersed in the polymer matrix. The permeability coefficients and selectivity of PMMA grafted silica / 6FDA based polyimide nano composite film increased with increasing silica content. This kind of nano composite membrane is expected to be a high-performance gas-separation membrane.
