Abstract

Expanded polyvinyl-alcohol (PVA) was successfully prepared using a similar process to that of starch expansion. The addition of an iodine solution was necessary to facilitate expansion and led to surface areas of up to 143.1 m(2) g(-1). The use of recycled material from LCD screens required no additional iodine and produced an expanded material with high surface areas (95.0 m(2) g(-1)) and total pore volumes (0.56 cm(3) g(-1)). The PVA-iodine complexes were found to better mimic the interactions between amylose and amylopectin in starch expansion.
