| 摘 要： | 采用超临界CO2注入技术制备聚合物-无机纳米粒子复合材料,以乙醇作为共溶剂,在超临界CO2中将正硅酸乙酯(TEOS)注入到聚丙烯(PP)中,重点研究共溶剂乙醇对TEOS在PP中注入率的影响.实验结果表明注入率随着共溶剂加入先增加后减小.同时研究了在共溶剂的存在下其他实验条件对注入率的影响.并采用卢瑟福背散射能谱法(RBS)分析了聚丙烯/SiO2纳米复合材料的注入元素深度分布,发现Si元素在PP中的浓度分布不均匀,随着深度的增加而减小. |

| Abstract: | Polymer/inorganic hybrid materials were prepared by supercritical carbon dioxide (scCO2) impregnation.Tetraethyl orthosilicate (TEOS) was infused into polypropylene (PP) strips in scCO2 using ethanol as the co-solvent.The effect of this co-solvent on mass uptake was investigated.We found that the mass uptake of TEOS into PP strips increased to a maximum and then decreased after the addition of more co-solvent.The effects of other impregnation conditions on the mass uptake were also investigated with using e... |
