Layer-by-layer deposition of polyelectroiyte complexes for the fabrication of foam coatings with high loading capacity

摘要

Robust macroporous foam coatings with high loading capacity were rapidly fabricated by layer-by-layer deposition of oppositely charged photo-reactive polyelectroiyte complexes combined with subsequent photo-reaction.rnIn recent decades, more and more efforts have been paid to prepare diverse porous polymeric materials by methods such as colloidal templating, micelle templating, phase separation of block copolymers, CO_2 foaming, and so forth. Polymeric films with well-designed porosities are of great interest for their potential applications in separations, sensors, antireflection coatings, tissue engineering and catalysts.
