利用常压介质阻挡放电(APDBD)和低压辉光放电(LPGD)等离子体分别对聚丙烯(PP)非织造布进行亲水改性.分析了气体种类、压强、放电频率、电压、处理时间以及非织造布物理结构等因素对亲水改性的影响规律.采用傅里叶变换一表面衰减全反射红外光谱(FTIR-ATR)表征材料表层化学结构的变化,选用吸水率和吸水速率评价样品的亲水性.结果表明:氧气等离子体能够比氩气等离子体更有效地提高非织造布的吸水率和吸水速率;增大放电频率和电压以及适当延长处理时间,均可显著提高材料的亲水改性效果;样品的比表面积越大,体积密度越小,材料的吸水能力越高.

Polypropylene(PP)nonwoven fabric(NWF)was treated by atmospheric pressure dielectric barrier(APDBD)plasma and low pressure glow discharge(LPGD)plasma,respectively.The influence of plasma gas,pressure,discharge frequency,discharge voltage,treatment time and the physical structure of PP NWF on the hydrophilicity improvement was studied.Fourier-transform infrared-attenuated total reflection(FTIR-ATR)spectroscopy was employed to analyze chemical structure changes on the sample surface.Water absorption ratio and rate were used to evaluate hydrophilicity modification effect.It was found that oxygen plasma could give a better treatment effect than argon plasma.Either increasing of discharge frequency or treatment time can both improve the hydrophilicity.Larger specific surface areaand smaller density of the sample could lead to higher water absorption capability.
