摘要
以1,2-二溴乙烷、4,4-联吡啶、醋酸铜为原料,聚丙烯(PP)和纤维素组成的双层水刺非织造材料为基底,通过溶剂热法制得Cu-MOF(铜基金属有机框架材料)/PP/纤维素复合水刺非织造材料。利用扫描电镜、X射线衍射、红外光谱仪等对复合材料的形貌和结构进行表征,并研究了其对水溶液中酸性橙7的去除能力。结果表明:Cu-MOF主要负载于非织造材料的纤维素表面上,且呈现花朵状;改性后,复合材料的拉伸强度断裂伸长率略有下降,拉伸模量基本没有变化;在60min内,对浓度为5mg/L的酸性橙7的去除率达到90%,经5次循环后的去除率仍在60%以上。
Cu-MOF/PP/cellulose spunlaced nonwovens were synthesized with the solvothermal method by using 1,2-dibromoethane,4,4-bipyridine and copper acetate as raw materials and the double spunlaced nonwoven composed of polypropylene(PP)layer and cellulose layer as substrates.The morphology and structure of the Cu-MOF/PP/cellulose composite were characterized by scanning electron microscopy,X-ray diffraction,infrared spectroscopy,and so on.Then the removal ability of the composite for acid orange 7in aqueous solution was studied.The results showed that the Cu-MOF was mainly loaded on the cellulose surface of the nonwoven material,and presented the flower shape.After the modification,the tensile strength and elongation at break of the composites decreased slightly,while its tensile modulus remained unchanged.Within 60minutes,the removal rate of the composite for aid orange 7with concentration of 5mg/L reached 90%.After five cycles,the removal rate of the composite was still over 60%.
