| DETERMINATION OF THE OPTIMUM AMOUNT OF COUPLING AGENT WITH CONTACT ANGLE METHOD |
|
| 摘要: 偶联剂是一类能在无机填料和聚合物基材之间形成“分子桥”、改善两者之间相容性或提高两者之间相互作用能力的化合物。将经偶联剂改性的无机填料填充到聚合物中可以制得成本低、性能好的复合材料[1,2]。由于偶联剂用量多少将对复合材料的性能产生较大影响[3],因此建立一种准确、简便地确定偶联剂最佳用量的方法有着十分重要的理论和实际应用意义。 |

| Abstract: In this paper the influence of the amount of coupling agent (NDS-01) on the disperse part of the surface energy Xsd(Xsd=rsd/ (rsd+sp) is studied by determination of contact angle. It is found that rsd increases firstly and then decreases a little after reaching its maximum point with the increase of NDS-01 amount. Comparing with mechanical properties of filled polyolefine, we concluded that the amount of coupling agent which results in the maximum of rsd may be taken as the optimum one. The results of determination of contact angle are more exact than those of other methods. |
