The present invention relates to a process for surface treatment of a solid substrate in which photopolymerisation and covalent grafting are performed in situ on said substrate of a biocidal copolymer, wherein steps are taken in which: a) said solid substrate is put in contact with a formulation comprising: 1—at least one monomer comprising a biocidal group, 2—at least one copolymerisable compound with said biocidal monomer comprising a multifunctional monomer or oligomer mono- di- or selected amongst acrylate, epoxide or vinyl ether monomers or oligomers, 3—at least one photoprimer selected amongst radical and/or cationic photoprimers, and 4—at least one grafting agent on said substrate, and b) photocopolymerisation and covalent grafting of the copolymers obtained are carried into effect by subjecting said formulation in contact with said solid substrate to ultraviolet radiation.
本发明涉及一种对固体基材进行表面处理的工艺,在该工艺中,在所述基材上对杀菌共聚物进行原位光聚合和共价接枝,其中采取的步骤包括:a) 将所述固体基材与一种配方接触,该配方包括:1-至少一种包含杀菌基团的单体,2-至少一种可与所述杀菌单体共聚的化合物,该化合物包含多功能单体或低聚物,单-二-或低聚物:1- 至少一种含有杀菌基团的单体; 2- 至少一种可与所述杀菌单体共聚的化合物,包括多功能单体或低聚物,单-双-或从
丙烯酸酯、
环氧化物或
乙烯基醚单体或低聚物中选择、3- 至少一种从自由基和/或阳离子光聚合物中选出的光聚合物,以及 4- 至少一种在所述基底上的接枝剂,以及 b) 通过将与所述固体基底接触的配方置于紫外线辐射下,实现所获得共聚物的光聚合和共价接枝。
