摘要/Abstract

摘要： 基于层层沉积法,引入简单易控的热处理方式在玻璃基底表面制备出高结晶度且致密无裂缝的Cu₃(BTC)₂膜,并详细探讨热处理温度、组装时间和组装溶剂对Cu₃(BTC)₂成膜的影响。FESEM分析结果显示:膜层的厚度仅为200 nm;热处理有利于获得完整的晶体结构,且高温下膜层不会产生裂纹;组装时间为5 min或10 min,Cu₃(BTC)₂ 颗粒尺寸小且均一。然而,当组装时间延长至20 min,尺寸变得不均一,膜层表面变粗糙;通过改变组装溶剂环境,可以制备出不同维数的晶体膜。

Abstract: Based on layer-by-layer deposition,heat treatment was introduced to prepare continuous and defect-free Cu₃(BTC)₂ film on glass substrate.The effects of some parameters including heat treatment temperature,assembly time and solvent were investigated with field emission scanning electron microscopy(FESEM).The results showed that film thickness was only about 200 nm which was much thinner than those previously reported.Heat treatment was fantastically beneficial for high crystallinity Cu₃(BTC)₂ film formation and no crack was found in the film even at a high heat treatment temperature. At the assembly time about 5 min or 10 min,small crystal particles with uniform size were obtained. However,at a longer assembly time of 20 min,particle size became non-uniform,leading to film unevenness. Moreover,by changing the assembly solvent environment,films with different dimensions were formed.

Key words: metal-organic frameworks, Cu₃(BTC)₂, film, layer-by-layer deposition, heat treatment, surface, polymer
