Glass Transition Properties of Biomaterials(The Articles of the Society Award Winners)

Abstract

Glass transition temperature (T_g) of biomaterials including pharmaceutical and food materials is a practically important factor. However, it is difficult to obtain a clear T_g because biomaterials are complex and heterogeneous system. In this paper useful techniques for the T_g determination of biomaterials were briefly reviewed. Isothermal aging and cooling-heating cycle rate can emphasize glass transition observed by differential scanning calorimetry. Thermal rheological analysis can provide additional information on the glass transition of biomaterials.
