摘要

我们证明了镁层羟基盐（LHS）纳米晶体分散体的合成是一种有前途的可降解和潜在的生物相容性材料。在丙烯酸（AA）为聚合抑制剂的条件下，通过环氧丙烷碱化反应，成功合成了10 nm以下的镁LHS纳米晶体。在AA/Mg = 2.0的优化组合下，嵌入AA的纳米镁LHS形成透明分散体。将所得的镁- LHS纳米晶体与聚γ-谷氨酸钠（γ-PGA-Na）混合，并采用静电纺丝法研究其制备纤维材料的性能。结果表明，γ-PGA-Na与镁LHS纳米晶之间的相互作用使材料被加工成纤维结构。

Synthesis of colloidal nanocrystals of magnesium layered hydroxide salt and their application as nonwoven fabric materials

We demonstrate the synthesis of dispersions of magnesium layered-hydroxide-salt (LHS) nanocrystals as promising degradable and potentially biocompatible materials. Sub-10 nm magnesium LHS nanocrystals were successfully synthesized through the alkalization reaction using propylene oxide in the presence of acrylic acid (AA) as an aggregation inhibitor. At the optimized compositions of AA/Mg = 2.0, transparent dispersion of nanometric magnesium LHS formed with intercalating AA. The obtained magnesium LHS nanocrystals were mixed with poly(sodium γ-glutamate) (γ-PGA-Na), and the capability of producing fiber materials was investigated using the electrospinning method. It was found that the interaction between γ-PGA-Na and magnesium LHS nanocrystals enabled the material to be processed into fibrous structures.
