Preparation of Thermoresponsive Chitosan Polymers and Its Application Controlling Release of Antifouling Agent
Thermoresponsive chitosan copolymers embed with antifouling agent paeonol in chitosan(CS) microparticles were prepared and the release dynamics was studied at different temperature.Chitosan microparticles have been formed based on ionic gelation process of CS and sodium tripolyphosphate (TPP).Paeonol was incorporated into the CS microparticles with the size about 0.1 μm.The physicochemical structure of samples was analyzed by FTIR and scanning electron microscopy (SEM).We investigated the influence of sodium tripolyphosphate (TPP) and paeonol on Encapsulation efficiency.Increasing TPP concentration from 1 to 3 mg/ml increased encapsulation efficiency of paeonol from 63% to 92%.Increasing peaonol concentration from 1.0 to 3.0 mg/ml increased peaonol encapsulation efficiency from 72% to 85%.
