| 摘 要： | 通过在核壳聚合物聚(苯乙烯-丙烯酰胺)微球表面吸附Ag+继而用紫外灯光照还原,制备了P(St-AM)@Ag复合微球。采用扫描电子显微镜、紫外可见反射光谱、X-射线粉末衍射对P(St-AM)@Ag复合微球进行了表征,并研究了复合微球的气敏性。结果表明,所制备P(St-AM)@Ag复合微球对乙醚蒸气具有良好的响应性和响应稳定性,复合微球粒径越小、微球表面包覆的Ag越多,响应性越大,粒径205nm的P(St-AM)@Ag复合微球在饱和乙醚蒸气中的最大响应性可达3.12。

| Abstract: | Poly（styrene-acrylamide） microspheres coated by nanoparticles of silver P （St-AM） @ Ag] were fabricated by adsorbing Ag＋ on the surface of poly（styrene-acrylamide） microspheres, following with reduction irradiated by UV light. The as-prepared P（St-AM）@Ag were characterized by scanning electron microscopy, UV-visible reflectance spectrum and X-ray diffraction. The vapor response properties of P（St-AM）@Ag com- plex microspheres were studied. The results demonstrated that P（St-AM）@Ag were of good responsiveness and responsive stability to ethyl ether vapor,the smaller particle size of P（St-AM）@ Ag were complex micro- spheres, the more loading amount of Ag＋ on microspheres,its vapor responsiveness was the higher. The maxi- mum responsiveness of P（St-AM）@Ag complex microspheres with particle size of 205 nm was 3.12 in saturat- ed ethyl ether vapor. |
