- Carbohydrate Polymers, 71(4), p.535-543, 2008 .
The effect of moisture content on tensile and fracture properties of a plasticised starch/high molecular weight polyol blend was investigated. A wide range of mechanical behaviour was achieved by varying slightly the water uptake of this material. At low moisture content, the Young's modulus was 3800 MPa and the yield stress, 54 MPa. When the moisture content reached 15 wt
