Polyelectrolytes complexes (PECs) are defined as materials formed by combining oppositely charged polyelectrolytes together via ionic interaction. PECs have some unique physical properties such as non-solubility in common organic solvents, high surface hydrophilicity, tunable surface charge, and stable structures. A new type of PEC based on chitosan (CS) and sulfonate poly(ethylene terephthalate) (SPET) were synthesized in two different media, buffer solution and salt solution acidified with acetic acid. Fourier transform infrared spectroscopy (FTIR), zeta potencial, X-ray diffraction, thermal gravity analysis and differential scanning calorimetry were used to characterize the chemical structure, particle charge, crystallinity and thermal s...
