Zero-birefringence pressure-sensitive adhesives
AIP Advances, 2012 We have developed zero-birefringence pressure-sensitive adhesives (PSAs) that exhibit almost no birefringence at any orientation of polymer chains. To evaluate the birefringence of PSAs quantitatively, we report a novel birefringence-measurement method ...
