A process for modifying the surface of an inorganic or organic substrate with strongly adherent nanoparticles is described, providing to the surface modified substrate durable effects like hydrophobicity, hydrophilicity, electrical conductivity, magnetic properties, flame retardance, color, adhesion, roughness, scratch resistance, UV-absorbance, antimicrobial properties, antifouling properties, antiprotein properties, antistatic properties, antifog properties, release properties. In this process, an optional first step a) a low-temperature plasma, ozonization, high energy irradiation, corona discharge or a flame is caused to act on the inorganic or organic substrate, and in a second step b) one or more defined nanoparticles or mixtures of defined nanoparticles with monomers, containing at least one ethylenically unsaturated group, or solutions, suspensions or emulsions of the afore-mentioned substances, are applied, preferably at normal pressure, to the inorganic or organic substrate. In a third step c) suitable methods are applied to dry or cure those afore-mentioned substances and, optionally, in a fourth step d) a further coating is applied on the substrate so pretreated.
本文描述了一种用强附着力纳米颗粒改性无机或有机基底表面的方法,使表面改性后的基底具有耐久性效果,如疏水性、亲水性、电导性、磁性、防火性、颜色、附着力、粗糙度、抗刮擦性、UV吸收性、抗菌性、防污性、抗蛋白质性、抗静电性、防雾性和释放性。在此过程中,第一步(可选)是在无机或有机基底上施加低温等离子体、臭氧化、高能辐射、电晕放电或火焰,第二步(b)是将一个或多个定义的纳米颗粒或定义的纳米颗粒与至少一个乙烯基未饱和基团的单体,或上述物质的溶液、悬浮液或乳液,应用于无机或有机基底上,最好是在常压下进行。第三步(c)是应用适当的方法干燥或固化上述物质,可选地,在第四步(d)中在预处理的基底上施加进一步的涂层。
