I have fabricated chitosan acetate films and exploring their TS, Young's modulus and percent elongation/ductility. But they have shown a fluctuating trends. Generally it has been said that with the increasing TS value the ductility have shown a decreasing trend and vice-versa regarding the subjected samples. Though there is a very irragular relationship between the TS and Young’s modulus. But I am verymuch confused about the unexpected behaviour of the considered biopolymeric samples like chitosan-acetate films regarding the TS, Young's modulus and ductility. Therefore, if you are an expert in this particular field please justify the reason behind the seance.
