Abstract
Methods for generating metallic particles in situ in a polymer are disclosed. A method includes (a) contacting the polymer with a solution comprising (i) a solvent, (ii) a metal salt, and (iii) a free radical generator; (b) removing the polymer from the solution; and (c) exposing the polymer to actinic radiation. Polymer composites and polymer nanocomposites comprising inorganic particulates comprising metallic particles generated in the polymer are also disclosed.
Claims9
A method for generating metallic particles in situ in a solid polymer, comprising:
- (a) contacting the polymer with a solution comprising:
- (i) a solvent,
- (ii) a metal salt, and
- (iii) a free radical generator;
- (b) infusing the solution into the solid polymer surface;
- (c) removing the polymer from the solution that has not been infused into the polymer surface;
- and
- (d) exposing the polymer to actinic radiation to generate metallic particles in situ in the surface regions of the polymer.
