The experimental results proclaimed:the foamability and the foam stability of ionic surfactant system was qualified than nonionic surfactant system; and if the surfactant molecule was voluminous or the hydrophobic tail had many embranchments, the foamability and the foam stability were scrannel.

实验结果表明：离子型泡沫剂的发泡能力和泡沫稳定性要高于非离子型泡沫剂，对于同一类型的泡沫剂，分子体积庞大或者疏水链上有较多支链的泡沫剂的起泡性和稳定性差。

And the PLA/Chitosan/ACP barriers with additional 2 wt% chitosan still maintain 56.58 % antibacterial ability after eightieth day. The different composition of PLA/Chitosan/ACP composites was prepared by water washing solidification from NMP/water/lactic acid consolvent. After storing at room temperature for 48 hours and taking it out to obtain a shapable composites. To investigate the influence of ratio of composition with the shapable property of composites, it was analyzed by Rheometer, TGA, AFM, XRD. The result of the different APC content had different effect both water content and yield stress of composite materials. The yield stress decreased with ACP content while increases. It was derived that ions, released from ACP interact with amide groups of chitosan to form water-absorbing ionic clusters through chelating or electrostatic attraction.

另外，以聚乳酸/几丁聚醣作为基材并添加不同比例的非晶型磷酸钙，经过水洗固化后可得白色片状沉淀物，於室温下静置48小时后，复合材之体积呈现膨胀且具有可塑形之特性，以热重分析仪与流变仪分析样品之含水率与屈伏应力，结果显示不同ACP含量对复合材含水率与屈伏应力具有消长变化，而PLA/Chitosan/ACP之可塑程度与其所吸收之水份多寡有关，推测可能机制为ACP磷酸钙盐解离后之金属离子与几丁聚醣之胺基透过螯合作用或静电吸引之交互作用，形成具吸水性之离子团簇分散於疏水性之聚乳酸基材中。

The porous poly (vinylidenefluoride-co-hexafluoropropylene) membranes, which doped with various amounts of silicotungstate lithium(Li4SiW12O40),were prepared by liquid-liquid extraction in this paper.
