The results show that the addition of cross-linker makes tensile strength of the material greatly increase. After the addition of dialdehyde starch, the tensile strength raises from 7. 2MPa to 13. 2 MPa. However, the strength of the material cross-linked by TDI greatly increases when the additive level is less than 10％ while the tensile strength of sample whose additive level is 20％ is even worse, which is mainly caused by the inner-flaw after cross-linking.

结果表明，交联剂的加入使材料的强度得到较大的改善，添加双醛淀粉后，材料的强度从原来的7.2MPa提高到13.2MPa，而添加TDI的材料在添加量10％以前强度有较大的提高，但20％添加量的样品的强度却很差，主要是由于形成的内部缺陷造成的。
