摘　　要：采用共面介质阻挡放电(CDBD)和常压等离子体化学气相沉积(APECVD)的方法裂解六甲基二硅氧烷(HMDSO),对芳纶织物进行单面处理,在其表面沉积颗粒,达到表面改性效果。通过扫描电子显微镜(SEM)、傅里叶变换红外光谱(FTIR)、亲水性测试、热通量测试等方法研究芳纶织物处理前后的表面形貌、亲水能力和隔热性能变化。结果表明:等离子体处理后,芳纶紧贴电极面受到刻蚀,粗糙程度明显增加;纤维的化学组成没有显著变化,仅—OH—等极性基团有所增加;芳纶织物的亲水能力显著改善;在HMDSO沉积作用下,芳纶织物隔热性能明显提高。织物反面未能得到处理,达到单面处理多孔织物的效果。研究结果可为芳纶增强复合型材料的制备提供理论依据。The hexamethyldisiloxane(HMDSO)is cracked by coplanar dielectric barrier discharge(CDBD)and atmospheric pressure plasma chemical vapor deposition(APECVD).The aramid fabric is treated with one side and particles are deposited on the surface to achieve surface modification effects.Scanning electron microscopy(SEM),Fourier transform infrared spectroscopy(FTIR),hydrophilicity test,heat flux test and other methods are used to study the surface morphology,hydrophilicity and thermal insulation properties of aramid fabric before and after treatment.The results show that after plasma treatment,the aramid fiber is treated close to the electrode surface,and the roughness obviously increases after etching;the chemical composition of the fiber does not change significantly,only the polar groups such as—OH—increases.The hydrophilic ability of the fabricis significantly improved;under the action of HMDSO deposition,the thermal insulation properties of the aramid fabric are significantly improved.The reverse side has not been treated,and the effect of single-sided treatment of porous fabric is achieved,which can provide a theoretical basis for the preparation of aramid reinforced composite material and has a good application prospect.
