機能化ナノ粒子による表面特性の変更

Japanese Patent JP5568311

B2

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.
