Effects of Substrate, Solvent, Graft Density and Graft Length on the Formation of Cellulose-Based Ordered Porous Film

Abstract:

We investigated the preparation of porous film of cellulose-based graft copolymer by breath figure method. The effects of substrate, solvent, graft density and graft length on the formation of porous film were elucidated. The results showed that ordered porous films could be facilely formed on the glass and mica substrate, while no ordered porous films were obtained on the silicon substrate. The ordered porous films were formed from the copolymer/CS₂ solution, while no ordered porous films were done from the copolymer/CH₂Cl₂, CHCl₃ and toluene solution. Moreover, no ordered porous films were obtained from the copolymer with spare graft density or with long side chain. The results indicated that the substrate, solvent, graft density and graft length had important effects on the ordered porous film.
