Anisotropic polymer meshes, which have micrometre-scale rectangular pores, were prepared by simple stretching and photo-crosslinking of poly(1,2-butadiene) honeycomb films. First, honeycomb films with pores of uniform size were prepared by a simple self-organization process. Then, after stretching and UV photo-crosslinking, anisotropic polymer meshes were formed. These anisotropic polymer meshes had high chemical and thermal stability, and exhibited anisotropic wettability. Moreover, by using a photo-crosslinking process, the anisotropic meshes could be photo-patterned. These anisotropic polymer meshes are expected to be applicable to digital microfluidic devices, cell aligners, and other such devices.
各向异性聚合物网格由聚（1,2-丁二烯）蜂窝薄膜的简单拉伸和光交联制备而成，具有微米级矩形孔。首先，通过简单的自组织过程制备具有均匀尺寸孔的蜂窝薄膜。然后，在拉伸和紫外光交联后，形成各向异性聚合物网格。这些各向异性聚合物网格具有高化学和热稳定性，并表现出各向异性润湿性。此外，通过光交联过程，可以对各向异性网格进行光图案化。这些各向异性聚合物网格有望应用于数字微流控器件、细胞对齐器和其他此类器件。
