1. A process for making multifunctional smart particles that comprises:
combining a corrosion inhibitor compound or antimicrobial compound with a complexing agent in aqueous solution to form dissociable complexes having a size within the range of 50-500 nm and that are suspended within said solution;
adding to the suspension of dissociable complexes a matrix-forming structural agent and allowing the matrix to form porous matrix solids around the dissociable complexes to form smart core particles of dissociable complexes dispersed throughout pores in said matrix, said smart core particles having exterior surfaces; and
contacting the smart core particles with a functional surface modification agent selected from the group of hydrophobic agents and/or antimicrobial agents and allowing the surface modification agent to react with at least a portion of the smart core particle exterior surfaces and thereby impart hydrophobic and/or antimicrobial effects to the resulting smart particle.
