poly(aminoacetyloxyethylaspartamide) hydrochloride(PAAEA·HCl) was prepared starting from L-aspartic acid.The polyelectrolyte complex nanoparticles were formed via the electrostatic interaction between poly(aminoacetyloxy-ethylaspartamide) hydrochloride and sodium carboxymethylcellulose.The effects of polyion concentration
solution properties
solution ionic strength on the sizes and zeta potentials of the formed nanoparticles were investigated.The size and ξ-potential of nanoparticles
