摘要

本文研究了在0.01%溴苯溶液中生长的聚氧亚甲基单晶在可变形基质上的变形。在复合材料的机械变形之前，用金对晶体表面进行轻微的修饰，显示出相对于下面聚合物晶体中的裂纹而移位的金的断裂。这些观察结果被解释为暗示在聚合物晶体表面存在一层非常薄的离散膜，该膜在变形过程中会滑动。这种薄膜可能是由吸附在晶体表面的聚合物分子形成的。

Surface Films on Poly(oxymethylene) Single Crystals.

The deformation of single crystals of poly(oxymethylene) grown from 0.01 percent bromobenzene solution has been studied by deposition on a deformable substrate. Slight decoration of the crystal surfaces with gold prior to mechanical deformation of the composite reveals breaks in the gold which are displaced with respect to cracks in the underlying polymer crystals. These observations are interpreted to imply the existence of a very thin discrete film on the surface of the polymer crystals which can slip during deformation. Such a film might arise from polymer molecules adsorbed on the crystal surface.
