摘　　要：高性能功能材料在诸多领域具有广泛的应用前景,是人们一直关注的研究热点。高压可以有效地改变物质的原子间距和成键方式,是获得新型功能材料的重要途径。在碳材料的高压研究中,许多有趣的功能碳材料,如光学透明碳、高强度弹性碳和超硬非晶碳等,已经通过不同的碳前驱体合成。本文简要介绍了作者近年来在低维碳基纳米复合材料高压研究中取得的进展,基于设计的不同低维碳前驱体,高压下截获了具有超硬特性、新型压致共价聚合及发光增强的碳材料。Functional materials with highly desirable properties have been highly pursued for a long time due to their potential applications in many fields.High pressure can effectively reduce the interatomic distances and modulate the bonding patterns of materials without changing their chemical compositons,which has been considered as a powerful and important approach to design new functional materials with desired structures and properties.Many interesting types of functional carbon materials,such as optical transparent carbon,super strong and elastic carbon,and ultrahard bulk amorphous carbon have been obtained from different carbon precuresors under high pressure.Recent progress on the high pressure research of low dimensonal carbon composite materials are introduced.Based on the predesigned carbon-based precursors,new carbon materials with superhard properties,covalent polymerization and anomalous photoluminescence enhancement by the application of high pressure have been obtained.
