Method of Fabricating Microporous Elastomer Thin Films with Controllable Surface Pore Morphology and Monomodal Pore Size Distributions
Non-Confidential description of the invention
The present invention relates to a method of fabricating microporous elastomer 5 thin films especially made of polydimethylsiloxane (PDMS) with finely tunable surface pore morphology and monomodal pore size distributions. The present invention particularly relates to a method of fabricating microporous PDMS thin films using ethyl acetate as the diluent and water as the porogen. It is a method for fabricating microporous PDMS elastomer thin films using predetermined amounts of a liquid elastomer (PDMS), a diluent and a liquid porogen. Also, provided herein are microporous PDMS elastomer thin films with controllable pore morphology and monomodal pore size distributions on the surface and the bulk over large areas. Microporous elastomer thin films especially made of polydimethylsiloxane (PDMS) with controllable pore morphology and size distribution have huge application potentials in the fields of cell culture & tissue engineering, targeted drug deliveries, stretchable bioelectronics for medical devices, semi-permeable membranes for biogas and CO2 detection and wound healing bandages. Owing to high biocompatibility and biostability, microporous elastomer (PDMS) thin films are excellent candidate for above applications.
