以丙三醇(甘油)作为塑化剂对淀粉进行塑化
得到热塑性淀粉(TPS)
以聚乙烯醇(PVA)和有机蒙脱土(OMMT)作为变量
制备TPS/PVA/MMT复合材料.采用X-射线衍射(XRD)表征了TPS/PVA/MMT复合材料和OMMT的晶层结构.使用扫描电镜(SEM)观察了玉米淀粉、TPS及TPS/PVA/MMT复合材料的微观结构.研究结果表明
机械共混法使TPS有效地插层到了OMMT的片层中
随着OMMT含量的增加
TPS/PVA/MMT复合材料的力学性能在升高
吸水性能在不断降低.当OMMT含量为5%时
TPS/PVA/MMT复合材料的力学性能和耐水性都达到了最好.
TPS/PVA/MMT composite materials were synthesized by thermoplastic starch(TPS) with glycerin as a plasticizing agent on starch plasticizing and polyvinyl alcohol(PVA) and organic montmorillonite(OMMT) as variables. The crystal layer structure of TPS/PVA/MMT compound materials and OMMT was characterized with X-ray diffraction(XRD)
the results show that mechanical blending method makes TPS effectively intercalate to OMMT slice layers.The microstructure of corn starch
TPS and TPS/PVA/MMT composites was characterized with scanning electron microscopy(SEM).The effects of various factors
the mechanical properties of TPS/PVA/MMT composite are on the rise
its bibulous performance in continuous reduction along with the increase of the content of OMMT.When the content of OMMT is 5%
the mechanical properties and water resistance of TPS/PVA/MMT compound composites have reached the best.
