摘要
采用低温等离子体技术对PBO纤维表面进行处理,通过单因素试验和正交试验分析了放电功率、放电时间和放电真空度对PBO纤维强力、摩擦因数的影响。结果表明:等离子体处理功率越大、处理时间越长、处理真空度越大,PBO纤维表面处理效果越强烈。等离子体处理参数为功率200 W、时间240 s、气压20 Pa。处理后的PBO纤维用扫描电子显微镜(SEM)、傅里叶红外光谱(FT-IR)、X射线衍射(XRD)、同步热分析仪(DSC/TG)等进行性能测试,结果发现:PBO纤维经等离子体处理后,纤维表面出现明显的凹槽和凸起,表面粗糙度增加,—OH、—CH3等活性基团的引入提高了纤维的表面活性,晶格结构基本保持不变但结晶度略微下降,热学性能保持良好。
Low temperature plasma technology is applied to surface modification of PBO fiber. The influ- ences of power, time and pressure of air plasma discharging on tensile and friction coefficient of the PBQ fiber are analyzed through single factor tests and orthogonal experiments. The results indicate that the modification of PBO fiber is more intensive with greater discharge power, longer treatment time and lower discharge pressure, and the optimum treatment parameters are discharge power 200 W, treat- ment time 240 s and discharge pressure 20 Pa. Testing results based on scanning electron microscopy （SEM）, Fourier transform infrared spectroscopy（FT-IR）, X-ray diffraction（XRD）, simultaneous thermal anal- ysis（TG/DSC）, etc show that, surface roughness of PBO fiber is increased as there are obvious grooves and bumps on the surface; the surface activity of the fiber is increased due to the introduction of the re- active groups, such as -OH, -CH3; lattice structure remains the same but the crystallinity is decreased slightly.
