Water-Based Iodinated Polymer Latex
Abstract

The present invention relates to an iodinated polymer latex, a water-based composite functionalized with an antimicrobial system. Specifically, this invention pertains to iodinated polymer latex where the antimicrobial component is glycol-based. When applied as a coating over surfaces, particularly the walls of a house, this invention can effectively control the formation of biofilm and mold. The entire system is designed to target and prevent biofilm formation on surfaces or walls.

Uniqueness of the Solution
  • Developed Iodinated polymer latex, a water based composite functionalized with a polyol-based antimicrobial system 
  • Implemented the water-based iodinated polymer latex as a binder for coatings over the surfaces 
  • Formation of biofilm or mold on the surfaces could be controlled 
  • Displays superior antimicrobial activity and hydrophobicity 
  • Prevents moisture damage, bacterial adhesion, and biofilm formation 
  • Latex based polymer enhances the mechanical and thermal property of the substrate
Prototype Details

An antimicrobial water-based iodinated polymer latex composite comprising 99% to 95% of polymer latex (containing 42% solid contents selected from acrylates-based polymer) and 1% to 5% of antimicrobial agent comprising a mixture of antimicrobial compound, glycol-based solvent and water-soluble polymer has been proposed. The acrylates-based polymer is selected from Poly Methyl Methacrylate (PMMA), Polystyrene Butyl Acrylate (PSBA) or a copolymer of Methyl Methacrylate and Butyl Acrylate [P(MMA/BA)] latex synthesized through emulsion polymerization. the water-soluble polymer containing in the ethylene glycol is polyvinyl pyrrolidone (PVP). The following steps have been defined for the preparation- preparing Polymer latex dispersion, preparing iodine solution, blending iodine solution in polymer latex dispersion to obtain water based iodinated polymer latex and finally the fabrication of iodinated latex film

Current Status of Technology

The invention has a proof of concept developed. A process for the preparation of water-based iodinated polymer latex has been proposed. It has also been tested for its antimicrobial activity.
