Nanosilver nano hydrogel product as antimicrobial coating and additive materials for healthcare devices

摘要

This invention relates to a process for the preparation of a nano-silver-nanohydrogel comprising the steps of preparing an aqueous silver nitrate solution and adding a monomer thereto followed by thorough mixing to obtain a nanoemulsion, adding a surfactant to the nanoemulsion to obtain a stabilized nanoemulsion, separately mixing a surfactant with an organic solvent and an initiator to obtain the oil phase, mixing the nanoemulsion with the oil phase to obtain a solution, subjecting the solution to polymerization followed by irradiation, adding a solvent thereto to obtain the nanosilver-nanohydrogel nSnH.
