| description | The main aim of this study was to investigate effects of eremurus tuber and dolomite on the properties of bio-films formed by a twin screw extruder. The bio-granules were formed with eremurus tuber (ET) or starch as natural polymers, glycerol as plasticizer, TiO2 as heat stabilizer and dolomite as fillers. Then the granules were converted to biofilms using a hot-press moulding. The physical (e.g. weathered test, colour measurement density, water absorption and solubility in different temperature, water vapour permeability, oxygen permeability and hardness), mechanical (e.g. tensile strength, elongation-at-break, modulus of elasticity), chemical (e.g. carbonyl-index and vinyl-index) and thermal characterizations (e.g., degradation temperature, melting point, enthalpy and crystallinity) were examined. The results showed that the interaction of the blend could attain melting properties (Tm) of the films although there were no Tm of pure eremurus tuber and starch. The eremurus tuber showed great improvement of water absorption, solubility and delaying water vaporization as well as weight loss after weathered in the films. Water diffusion into the films could be also inhibited with the eremurus tuber and dolomite due to their hydrophobic and cross-linker reaction with other additives. The dolomite filler was also an important performance for tensile strength, elongation-at-break, oxygen permeability, water interaction and aging resistance for the bio-blend films. The interaction of this blends could be probably followed with inter/intra-interaction of molecular. |
