The present invention relates to the field of materials; preferably to surfaces having biocide and/or bactericidal properties. Especially the present invention relates to a photoactivable surfaces and/or materials able to deliver singular oxygen as bactericidal agent; and the process for preparing such materials, said process comprising: (i) preparing a solution of at least one arylazide functionalized-photosensitizer; (ii) contacting the solution obtained at step (i) and a unmodified support; and (iii) covalently grafting by an insertion reaction, the arylazide functionalized- photosensitizer deposited on the support at step (ii), said insertion reaction being carried out by a thermal activation and/or a UV irradiation activation.
本发明涉及材料领域,尤其是具有
生物杀菌和/或杀菌特性的表面。特别是,本发明涉及一种可光活化的表面和/或材料,能够释放单一氧作为杀菌剂,并且涉及制备这种材料的过程,该过程包括:(i)制备至少一种芳基
偶氮苯官能化光敏剂的溶液;(ii)接触在步骤(i)中获得的溶液和未经修改的支持;以及(iii)通过插入反应共价嫁接在步骤(ii)中沉积在支持上的芳基
偶氮苯官能化光敏剂,该插入反应通过热活化和/或紫外辐射激活进行。
