Abstract
The invention features polymers with increased order, and methods of making them featuring a dense gas.
Claims25
A method of increasing the order of a polymeric material, said method comprising:
- (a) exposing said polymeric material to a dense gas system at a specific temperature greater than room temperature and at a pressure greater than atmospheric pressure;
- (b) applying an orienting force to said polymeric material, wherein step (a) and step (b) are performed during overlapping time intervals;
- and thereafter
- (c) removing some or all of the dense gas system from the polymeric material, thereby increasing the order of said polymeric material.
