正丁胺的等离子体聚合膜性质及氢离子响应功能研究

A Study on the Properties and H^+ Ion Sensitive Function of Poly(n-butylamine) Film Polymerized by Plasma

以正丁胺为单体，采用等离子体聚合法，在盖玻片与玻璃碳及一些金属基片上得到附着性和稳定性均良好的聚合膜．红外光谱、元素分析结果和睦性质研究表明；该聚合膜具有高度支化、交联的结构，具有良好的耐热和耐腐蚀性．以该膜为敏感材料制成的电位型化学传感器在强酸性溶液中对H+离子具有超能斯特响应，且稳定性和重现性较好．

Thin organic polymer films with properties of good chemicaI stability and good adhesion to glass and vitreous carbon and some metal substrates were prepared by plasma poly merization using n-butylamine as a monomer. Studies on IR spectrum and elemental analysis and other chemical properties showed that these polymer films had a very highly branched and cross-linked structure with good resistance to heat and erosion. The potential metric chemical sensors constructed by this kind of sensitive membranes of plasma poly (n-buty-lamine) gave a super-Nernst response to H+ ion in strong acid solution, and these electrodes had good stability and reproducibility.
