科學家研制出采用金屬有機化合物打造的新型玻璃
來源:www.szkingly.com 發(fā)布時間:2018-06-07


傳統(tǒng)玻璃的主要成分是二氧化硅,人們對制造過程中摻雜的硼、聚合物、以及金屬有一點印象。但是最近,賓夕法尼亞州立大學的研究人員們?nèi)〉昧艘豁椡黄?—— 打造了一種基于鋅的“金屬有機化合物玻璃”。 這種材料叫做 ZIF-62,結構式為被咪唑鈉(imidazolate)和苯并咪唑(benzimidazolate)分子包圍的一個鋅原子,這種新材料不僅更易形成玻璃、柔韌性更強、而且與石英玻璃擁有相同的金字塔形原子結構。

傳統(tǒng)工藝上,硅玻璃擁有的玻璃形成能力,但是研究人員指出,ZIF-62 的性能更加優(yōu)異。實際上,ZIF-62 的特性,已經(jīng)超越了現(xiàn)有的 50 種玻璃,并且比硅基玻璃更加柔韌。通過調整配方,研究人員發(fā)現(xiàn),苯并咪唑添加得越多、材料的玻璃形成能力就越佳。當然,與經(jīng)過數(shù)千年提純改進的硅基玻璃工藝相比,ZIF-62 也不是沒有缺點。在發(fā)展的初期,新材料還是難以與傳統(tǒng)工藝展開有力競爭的,為了制造全新的金屬有機玻璃,首先要形成有機化合物。

在未來,研究人員還計劃對其它金屬有機玻璃配方進行探討,包括可能的鈷基玻璃。
