聚合物基金属梯度复合膜合成中的电化学行为

STUDY ON ELECTROCHEMICAL SYNTHESIS OF METAL IN POLYMER GRADIENT COMPOSITE FILM

通过将聚合物-金属盐-有机溶剂三元浓溶液涂于阴极材料表面,干燥至一定程度,然后用电化学还原方法,制备了聚合物基金属梯度复合膜(MPGCF),对电化学反应体系及反应温度等重要条件进行了研究。结果表明,采用碳-碳-B液体系及碳-铜-C液体系时,均可合成结构可控的MPGCF,但以后者的合成条件更温和,适当提高介质温度,有利于MPGCF沉积和过渡层的形成。

The metal in polymer matrix gradient composite film (MPGCF) was synthesized by electrochemical reduction of a swelling cathode film(SCFs) made by homogeneous tricomponent solution of a polymermetal ion saltorganic solvent which was coated on a cathode surface and dried in air at ambient temperature to appropriate degree. Some important factors to the gradient structure were optimized and selected, such as various electrochemical conditions and temperature in electrochemical reactor. The results show that both the carbon anode and the copper anode can synthesize the MPGCFs of which the structures are controllable, the latter conditions are more moderate, higher temperature is helpful to form the metaldeposited layer and the transition layer.
