In this study, Chitosan-Poly complex nanoparticles were prepared by template polymerization of acrylic acid in the chitosan solution. The preparation and characterization of CS-PAA nanoparticles including the yields of the nanoparticles, FT-IR spectrum analysis, dynamic light scattering, zeta potential, and morphology of nanoparticles were concentrated in this study. The effects of temperature, weight ratio of CS and PAA, and pH value on the physicochemical properties of nanoparticles were studied.
