    • In the present invention method, the surface of articles made of acrylic polymers and methacrylic polymers are converted into thin biomimetic layers by using the process involving at least the following two steps:(a) The polymer surface is contacted, in the presence of water and for a predetermined reaction time necessary to form a continuous surface layer thinner than about 500 microns, with a solution containing one or more tetraalkylammonium hydroxides of the general formula:R.sub.1 R.sub.2 R.sub.3 R.sub.4 N.sup.+ OH.sup.-where R.sub.1, R.sub.2, R.sub.3, R.sub.4 are the alkyl substituents, in which the sum of the number of carbon atoms is equal to or larger than 8 but smaller than 45; and,(b) The article is removed from the aqueous reaction solution and excess of tetraalkylammonium hydroxide is removed from the polymer surface by washing the polymer with a liquid miscible with the tetraalkylammonium hydroxide.
    • 在本发明的方法中,由丙烯酸类聚合物和甲基丙烯酸类聚合物制成的制品的表面通过使用涉及至少以下两个步骤的方法转化成薄的仿生层:(a)聚合物表面在水和 对于形成薄于约500微米的连续表面层所需的预定反应时间,用含有一种或多种通式为R 1 R 2 R 3 R 4 N + OH的四烷基氢氧化铵的溶液,其中R 1,R 2,R 3,R 4为烷基取代基, 其中碳原子数之和等于或大于8但小于45; 和(b)通过用与四烷基氢氧化铵混溶的液体洗涤聚合物,从反应溶液中除去物品并从聚合物表面除去过量的四烷基氢氧化铵。
