本研究的目的是制备一种聚丙烯非织造布，具有从水介质中吸附阴离子和阳离子化合物的能力。采用氧等离子体对聚丙烯非织造布进行活化，接枝丙烯酸，然后采用轧-干-固化工艺在其上接枝聚丙烯亚胺树枝状大分子。研究了三个参数对树枝状大分子接枝率的影响，并采用响应面法优化了工艺。使用ATR-FTIR、FESEM、EDS、AFM和XPS分析所制备的样品。不同的分析结果证实了丙烯酸和树枝状大分子在聚丙烯非织造布表面上的接枝。XPS结果表明，在最佳条件下制备的样品含有胺和羧酸基团，使其能够与各种化合物相互作用。研究了丙烯酸接枝和树枝状大分子接枝样品对阴、阳离子模型染料的去除能力。树枝状聚合物接枝样品去除超过70%和99%的阳离子和阴离子染料从水中，分别。
The aim of this study is to prepare a polypropylene nonwoven with the ability to adsorb both anionic and cationic compounds from aqueous media. Polypropylene nonwoven was activated with oxygen plasma and acrylic acid was grafted on it. Then, poly(propylene imine) dendrimer was grafted on it by a pad-dry-cure process. The effect of three parameters on the dendrimer grafting yield was studied and the process was optimized using response surface methodology. The prepared samples were analyzed using ATR-FTIR, FESEM, EDS, AFM, and XPS. The results of different analyses confirmed the grafting of acrylic acid and dendrimer on the surface of the polypropylene nonwoven. The XPS results showed that the sample prepared under the optimal conditions contains both amine and carboxylic acid groups which enables it to interact with various compounds. The ability of acrylic acid grafted and dendrimer grafted samples for removal of model anionic and cationic dyes was studied. The dendrimer grafted sample removed more than 70% and 99% of cationic and anionic dyes from water, respectively.
