The AlCl3·6H2O aqueous solution was used to dissolve chitosan.
The thermal degradation of chitosan and poly(vinyl alcohol) was suppressed in AlCl3·6H2O aqueous solution.
Glycerol had the positive effect on AlCl3·6H2O doped chitsosan/poly(vinyl alcohol) film.
The high performance chitosan/poly(vinyl alcohol) films were obtained with AlCl3·6H2O and glycerol.
