事实上,聚(甲基丙烯酸2-羟乙酯)(PHEMA)与现代软性隐形眼镜的发明有着千丝万缕的联系。 时间回到20世纪50年代,某天欧美的报纸上报道了一种新奇的玩意儿叫做角膜接触镜(contact lens,俗称隐形眼镜)。报纸上刊印着年轻女性佩戴上隐形眼镜后微笑的照片,与佩戴框架眼镜相比,隐形眼镜不仅可以矫正屈光不正还使佩戴者看起来...

Solid Poly(2-hydroxyethyl methacrylate) (pHEMA) is brittle, while pHEMA hydrogel is a soft material. Glass transition temperature for pHEMA hydrogels is reduced by increasing a content of water in the matrix. Macromolecular properties in pHEMA are characterized by non-covalent interactions of hydrogen...
The blend miscibility of poly(2-hydroxyethyl methacrylate) (PHEMA) and poly(styrene-co-acrylamide) (PSAm) was studied by DSC. A miscible window was found in the range 47-57 mol% of acrylamide in blending PSAm with PHEMA (1:1 w/w) and was analysed by the mean-field theory. The water...
