Project Overview

Emulsion templating provides a method to prepare macroporous polymers. Usually high internal phase emulsions (HIPEs) or medium internal phase emulsions (MIPEs) are firstly prepared. After the polymerisation of the continuous phase and the removal of the internal phase of the emulsions, the products become polymeric foams (named polyHIPEs or polyMIPEs, respectively). In this project, we aim to prepare polyH(M)IPE films and develop their applications. Slicing monoliths of polyH(M)IPEs into films and casting and polymerising thin layer emulsion templates have been used by earlier researchers. We prepared successfully polyH(M)IPE films with open surfaces via these two routes. In addition, we also prepare polyH(M)IPE films via printing emulsion templates and polymerising them subsequently. This allows us to create patterns while making the macroporous films. We prepare functional polyHIPEs via biphasic emulsion templating route. The resultant hydrogel filled polyHIPE filled are expected to be applicable for ultra-filtration. On the other hand, we prepare polyurethane based polyH(M)IPE films via casting and UV-polymerising emulsion template thin layers. Different from polyH(M)IPEs based on St and DVB, which are brittle and chalky, the polyurethane based polyH(M)IPE films are very flexible. We aim to develop their applications in dielectric with pressure-sensitivity.
