METHOD FOR MODIFYING THE SURFACE PROPERTIES OF ELASTOMER CELLULAR FOAMS

摘要

The invention relates to a method for modifying a cellular polymer foam with apparent porosity, preferably made of polyurethane, which includes the following steps: a) providing a cellular polymer foam with apparent porosity (a); b) placing said cellular polymer foam in contact with at least one compound (b) selected among the compounds comprising at least one catechol unit, and preferably among the catecholamines, in order to obtain a cellular polymer foam including on the surface thereof an intermediate phase formed from said compound comprising at least one catechol unit. Said foam can be used as a catalyst substrate.
