The structures of the films determined with Fourier-Transformation Infrared Spectrum (FT-IR) after degradation.
The structure change of all films were studied before and after degradation by FTIR, and the degradation mechanism of the films were primary discussed.
As shown in Fig.1, 2, 3 before degradation, PLA, PBS, PCL films all have nicer surface crystalline form structure.
According to the conclusion of chemical structure by IR, the degradation mechanism of PBS may be cut off in any ester group in the chains.

Arising from their anomalous behavior, research on auxetic materials has been carried out for possible applications in fields as diverse as biomechanics and aero-structures.
