PMMA单分子膜成膜特性研究

Study on the properties of PMMA monolayer film

研究了ＰＭＭＡ单分子膜的成膜特性及其结构．结果表明，ＰＭＭＡ能够在较大的表面压范围内形成稳定的单分子膜，并且具有不可重复压缩性、表面压力的各向异性和松驰特性．ＴＥＭ照片显示。

Properties of poly(methylmethacrylate) (PMMA) monolayer film were studied. Data from our test indicated that a PMMA monolayer film could be formed, and it has nonrecompressibility, anisotropism and relaxation of surface pressure. TEM photograph showed orientation and arrangement of PMMA molecular chains in the monolayer.
