摘　　要：为进一步探索和研制高性能生物材料,以生物大分子葡甘聚糖为原材料,利用物理共混法制成复合高分子生物材料,探讨了温度、时间、电解质各因素对材料稳定性的影响。并通过DSC等分析手段从材料的动态粘弹性、相容性研究了复合材料的稳定机理。结果表明,生物大分子经共混后产生交联反应形成强度、韧弹性、稳定性等方面性能优良的复合生物材料,并初步提出生物大分子复合后形成了互穿型与内包型网络结构模式。By means of physical blending a composite macromolecule material was produced using biomacromolecule as the raw material, in order to develop new materials of excellent properties. Effects of temperature, time and electrolytes on the stability of material were discussed. A further study on composite material′s stability mechanism was made with considering its dynamic viscoelasticity and miscibility. The results show that a crosslink exist among biomacromolecules after blending, which lets to the success in creating high strength, plasticity, stability etc. composite material. The structure modes of composite material were supposed to be interpenetrating networks or a sing polymer network containing a second polymer within it.
