摘　　要：采用紫外光诱导接枝对PP熔喷无纺布进行表面改性,再进行抗菌处理得到抗菌PP无纺布。对其表面形貌、化学结构、抗菌性能等进行了表征。结果表明,表面改性的最佳工艺参数为:β-丙烯酰氧基丙酸(CEA)体积分数为8%,二苯甲酮(BP)体积分数为1%,紫外光辐照时间为60 min。接枝后PP无纺布的水接触角由123.1°变成31.6°。临界抗菌剂溶液处理浓度为20μg/mL,此时对S.aureus和E.coli的抑菌率分别达到90.9%和90.5%,抗菌性能良好且达到相关标准要求。In this study,surface modification of PP melt-blown non-woven fabrics was carried out using ultraviolet light irradiation and chemical grafting technology,and then the modified PP non-woven fabrics were treated to obtain an antibacterial polypropylene non-woven fabric.Moreover,surface morphology,hydrophilicity,chemical structure,and antibacterial properties were characterized.The results show that the best process parameters for surface modification are:β-carboxyethyl acrylates(CEA)volume fraction of 8%,benzophenone(BP)volume fraction of 1%,and UV irradiation time of 60 minutes.After the surface modification,the water contact angle of the PP non-woven fabrics was changed from 123.1°to 31.6°.The critical antibacterial agent solution concentration was 20μg/mL under which the antibacterial rates against S.aureus and E.coli reached 90.9%and 90.5%,respectively.This suggests the antibacterial performance is favorable and meets standard requirements.
