| 中文摘要: |
| 用分散聚合法制备聚甲基丙烯酸甲酯(PMMA)微球，以聚乙烯吡咯烷酮(PVP)为分散剂，依次用葡萄糖和硼氢化钠还原银氨溶液，在微球表面化学镀银，得到表面覆银的PMMA-Ag微球，对其进行了表征和分析。结果表明，微球分散性好，银层光滑致密，粒径较均匀，直径约2 μm；XRD图谱显示无银以外的其它物相存在；红外光谱显示银与PMMA微球的表面可能存在相互作用，是银还原沉积的影响因素；热重分析表明，PMMA-Ag耐热性有所提高(26℃)；制备使用的硝酸银占PMMA微球质量分数为55%时，样品的导电率最大(330 S/cm)。 |
| 英文摘要: |
| Poly(methyl methacrylate)(PMMA) microspheres were prepared by dispersion polymerization. The silver plated PMMA/Ag microspheres were obtained by using PVP as a dispersant and glucose and sodium borohydride solution as a reduction reagent to reduce a silver ammonia solution. The results showed that silver plated microspheres had good dispersibility, and that the silver layer was smooth and dense, and that the particle size is uniform, and that the diameter was about 2 μm. XRD patterns showed that there was no other phase except silver. Infrared spectrum showed that silver might interact with the surface of PMMA microspheres, which was the impact factor of silver reduction deposition. TGA showed that PMMA-Ag had improved heat resistance (26℃). When the percentage of silver nitrate in PMMA microspheres was 55%, the sample had the highest conductivity (330 S/cm). |
