Abstract
A process for preparing a biocidal, bactericidal and/or bacteriostatic material including the preparation of a polymer precursor solution that has (a) at least one monomer A having a porphyrin group and at least one radical polymerizable function, (b) at least one radical polymerizable monomer B, a photoinitiator, and (c) at least one of the monomers chosen from a monomer C having a quaternary amine and a radical polymerizable function; and/or a monomer D having copper and a radical polymerizable function. Also, the material obtainable by the process and its uses.

A process for preparing a biocidal, bactericidal and/or bacteriostatic material, said process comprising:
- (a) preparing a polymer precursor solution comprising:
- at least one monomer A having a porphyrin group and at least one radical polymerizable function,
- (ii) at least one radical polymerizable monomer B,
- (iii) a photoinitiator, and
- (iv) at least one of the monomers chosen from:
- (1) a monomer C comprising a quaternary amine and a radical polymerizable function;
- and/or
- (2) a monomer D comprising copper and a radical polymerizable function;
- (b) contacting the polymer precursor solution obtained in (a) with a support, resulting in the impregnation of said support with said polymer precursor solution;
- and
- (c) the implementation by UV irradiation of the polymerization of the polymer precursor solution impregnated in the support according to step (b), said UV irradiation being carried out at an absorption wavelength less than the wavelength maximum absorption λmax of monomer A;
- (d) optionally, activation by light irradiation of monomer A.
A precursor solution of a biocidal, bactericidal and/or bacteriostatic polymer, said solution comprising the mixture of:
- (a) at least one monomer A having a porphyrin group and at least one radical polymerizable function,
- (b) at least one radical polymerizable monomer B,
- (c) a photoinitiator,
- (d) at least one of the monomers chosen from:
- a monomer C comprising a quaternary amine and a radical polymerizable function;
- and/or
- (ii) a monomer D comprising copper and a radical polymerizable function,
- (e) optionally, a solvent.
