The study was carried out to prepare functional materials by the chemical modification of various fibers, which leads to the way of effective use of waste fibers. The cellulose fibers (cotton or rayon) were grafted with basic monomers,DMAEA and DMAPAA under various conditions by the UV irradiation. The optimum experimental conditions were determined. The obtained grafted cellulose materials adsorbed well anionic surfactant, LAS (linear alkyl benzene sulfonate) in water. In addition, acrylic acid was grafted on rayon and PET materials, and the obtained products were neutralized with sodium hydroxide. The obtained sodium acrylate grafted cellulose or PET chips adsorbed effectively ammonium ion in water and ammonium in air. As no effective theories on the adsorption science were given as far, we started to carry out the adsorption experiments of volatile organic compounds to fivers and synthetic polypeptides. The experimental results showed that the difference in polymer structures of fibers or polypeptides gave the difference in the adsorption of the compounds. The present study suggests that the very small difference in molecular structures in polymer materials can be seen by the simple adsorption experiment, which gives a novel, original research in future.

通过对各种纤维进行化学改性制备功能材料，为废旧纤维的有效利用开辟了一条途径。采用紫外光照射法，在不同条件下，用碱性单体DMAEA和DMAPAA对纤维素纤维（棉或人造丝）进行接枝改性。确定了最佳实验条件。所得接枝纤维素材料对阴离子表面活性剂LAS（直链烷基苯磺酸盐）具有良好的吸附性能。此外，还将丙烯酸接枝到人造丝和PET材料上，并将所得产物用氢氧化钠中和。所得的丙烯酸钠接枝纤维素或PET切片对水中铵离子和空气中铵离子都有较好的吸附效果。由于吸附科学尚未给出有效的理论依据，我们开始进行了河流和人工合成多肽对挥发性有机物的吸附实验。实验结果表明，纤维或多肽的聚合物结构的差异给出了化合物的吸附的差异。本研究表明，通过简单的吸附实验可以看出高分子材料中分子结构的微小差异，这为今后的研究提供了一种新的、原创性的研究方法。
