N - vinylpymolidone - co - 2 - hydroxyethyl methacrylate ( nw - co - hema ) copolymer had been widely studied and used as soft contact lens and controlled - releasing materials in foreign countrys . but this hydrogel material ' s oxygen penetration capability was closely correlated to its equation water content . when the hydrogel had high equation water content , its oxygen penetration capability was improved , but its mechanism performance was droped
N -乙烯基吡咯烷酮( nvp )和甲基丙烯酸-羟己酯( hema )的共聚物水凝胶作为软质接触透镜材料(隐形眼镜)和药物释控材料，在国外已经得到深入研究和应用，但是这种水凝胶材料的氧气透过性能与其平衡含水量密切相关，水凝胶含水量较高，其氧气透过性能有所提高，但材料的机械性能下降。
