应用1-辛烯涂层与常压等离子体处理的苎麻纤维疏水性能改性

Hydrophobic surface modification of ramie fibers with 1-octylene treatment and atmospheric pressure plasma treatment

为提高苎麻纤维与聚丙烯(PP)之间的界面相容性,采用1-辛烯涂层结合常压等离子体射流(APPJ)技术对苎麻纤维表面进行疏水性改性,并研究了改变2种方法的处理顺序对改性效果的影响。通过改性前后苎麻纤维的表面形态、润湿性、表面化学成分及苎麻纤维/PP界面剪切强度的变化分析改性效果。实验结果显示,经等离子体处理后再进行1-辛烯涂层处理的苎麻纤维表面的C元素含量提高最明显,且该组苎麻纤维/PP界面剪切强度与未处理组相比提高了近40.0%,而改变处理顺序后得到的苎麻纤维与PP的界面剪切强度仅提高了18.2%。

In attempt to improve the compatibility between hydrophilic ramie fibers and hydrophobic polypropylene（PP）, 1-octylene treatment and atmospheric pressure plasma jet （APPJ） treatment were used on ramie fibers. The influence of the treatment sequence on modification effect was also investigated in this study. Surface morphology, wettability, surface chemical constitution and interracial shear strength （IFSS） between ramie fibers and PP were studied to evaluate the modification effect. The result shows that fibers treated with plasma treatment followed by 1-octylene treatment get a most significant increase of carbon content and the IFSS between ramie fibers and PP increased by 40.0% , while fibers treated with 1-octylene treatment followed by plasma treatment show only 18.2% increase of the IFSS.
