摘要:

针对常压等离子体处理过程中存在水分的问题,研究回潮率对常压等离子体处理芳纶效果的影响。回潮率分别为0.5%、3.5%和5.5%的3种芳纶经常压等离子处理后,测定其动态接触角以及纤维与树脂间的层间剪切强度,采用原子力显微镜和X射线光电子能谱探测纤维表面发生的物理和化学变化。结果表明,随纤维回潮率的增加,处理后纤维的前进角和后退角减小,而纤维与树脂间的层间剪切强度、纤维表面的粗糙度以及极性基团增加,从而证明了纤维中水分的存在有助于常压等离子体改善芳纶的表面性能。

Abstract:

As to the existence of water in atmospheric pressure plasma (APP) treatment, the influence of aramid fiber moisture regain on the atmospheric pressure plasma treatment effects was investigated. The aramid fibers with different moisture regains (0.5%, 3.5%, 5.5%) were treated by atmospheric pressure plasma. The dynamic contact angle and the interfacial shear strength (IFSS) of the control and the treated fibers were measured. The morphological and chemical changes on the fiber surface were characterized by Atomic Force Microscopy (AFM) and X-ray Photoelectron Spectra (XPS) respectively. It was discovered that with the increment of fiber moisture regain, the advancing and receding angles were decreased, while the IFSS, roughness and polar groups on the treated fiber surface were increased. Therefore, it was concluded that the existence of water in fiber promoted the atmospheric plasma treatment effects in surface property improvement of aramid fiber.
