Preparation and characterization of single- and double-shelled cyhalothrin microcapsules based on the copolymer matrix of silica–N-isopropyl acrylamide–bis-acrylamide

Abstract

Silica and a copolymer of silica–<italic>N</italic>-isopropyl acrylamide–bis-acrylamide were used as a controlled release material for preparing single- and double-shelled cyhalothrin microcapsules.
