Abstract
A process for preparing a porous solid with an outer surface modified by at least one polymer; the polymer being simultaneously synthetized in solution and grafted on the outer surface of the solid, includes contacting: a porous solid; and a polymer-precursor solution comprising an adhesion primer, and at least one polymerizable monomer; under conditions enabling the formation of radical entities.
Claims17
Process for preparing a porous solid with an outer surface modified by at least one polymer;
- said polymer being simultaneously synthetized in solution and grafted on the outer surface of said solid, comprising contacting:
- a porous solid, wherein the porous solid is a particular solid, preferably selected from the group comprising alumina, hydroxyapatite, B-TCP, silica, zirconia, titania and/or a MOF solid;
- and
- a polymer-precursor solution comprising an adhesion primer, and at least one polymerizable monomer;
- under conditions enabling the formation of radical entities.
Porous solid with an outer surface modified by a polymer, wherein the size of the pores is modified by at most 20%, as measured preferably by BET.
Device comprising a porous solid with an outer surface modified by a polymer, wherein the size of the pores is modified by at most 20%, as measured preferably by BET, such as, for example, a medical device or a patch, wherein the porous solid preferably comprises an active principle in its pores.
Composition comprising a porous solid with an outer surface modified by a polymer, wherein the size of the pores is modified by at most 20%, as measured preferably by BET.
