摘要/Abstract

摘要：

采用慢气体扩散法, 以十八烯酸为软模板, 在天然木浆-聚酯纤维复合膜(Jetspun Cloth^TM膜)上仿生矿化原位合成碳酸钙. 衰减全反射傅里叶变换红外光谱表征和扫描电镜结果表明, 溶液中的部分十八烯酸会富集到Jetspun Cloth^TM膜上, 同时, 由于十八烯酸的羧酸根对钙离子的结合作用, 钙离子也被富集到Jetspun Cloth^TM膜上. 碳酸钙在Jetspun Cloth^TM膜的纤维上生长, 并最终形成碳酸钙薄膜-高分子纤维膜复合结构.

关键词: 仿生合成; 碳酸钙; 软模板; 硬模板

Abstract:

With oleic acid as soft template, the biomimetic synthesis of CaCO₃ on Jetspun Cloth^TM film was performed by slow gas diffusion method. The preadsorption of oleic acid and Ca²⁺ was characterized by the ATR-FTIR spectroscopy. The characterization of the deposition of CaCO₃ on Jetspun Cloth^TM film was carried out using scanning electron microscope, showing a CaCO₃-polymer film hybrid structure.

Key words: Biomimetic synthesis; Calcium carbonate; Soft template; Solid template
