Polymer film with high optical anisotropy

A polymer film characterized by a first in-plane refractive index (nx) in a first direction of the polymer film, a second in-plane refractive index (ny) in a second direction of the polymer film orthogonal to the first direction, and a third refractive index (nz) in a thickness direction substantial...

Beschreibung
Zusammenfassung:	A polymer film characterized by a first in-plane refractive index (nx) in a first direction of the polymer film, a second in-plane refractive index (ny) in a second direction of the polymer film orthogonal to the first direction, and a third refractive index (nz) in a thickness direction substantially orthogonal to both the first and second directions, where nxgt; nzgt; nzgt; ny. Such polymeric films may exhibit one or more of (a) an in-plane birefringence of at least about 0.05 and (b) an nx of greater than about 1.7. 一种聚合物薄膜，其特征在于沿聚合物薄膜的第一方向的第一面内折射率(nx)、沿聚合物薄膜的与所述第一方向正交的第二方向的第二面内折射率(ny)和沿与所述第一方向和第二方向两者基本上正交的厚度方向的第三折射率(nz)，其中nx>nz>ny。这样的聚合物薄膜可表现出(a)至少大约0.05的面内双折射和(b)大于大约1.7的nx中的一者或多者。
