| Research Abstract |
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.
