摘要

聚酰亚胺（PI）气凝胶具有优异的性能，近年来受到了人们的广泛关注，利用纳米颗粒改善气凝胶性能的研究也越来越多。在这项工作中，成功地制备了胺化功能化MXene纳米颗粒作为交联剂和无机增强相，均匀地嵌入PI气凝胶中，以合成一种新的PI复合气凝胶。结果表明，m-MXene可以作为交联点，有效地保持网络结构，进一步提高了尺寸稳定性和压缩模量。这些PI复合气凝胶具有高比表面积、低密度、低收缩和优异的机械性能。

Preparation and properties of aminated MXene cross-linked polyimide aerogels

Polyimide (PI) aerogels with excellent properties have received a lot of attention, and the use of nanoparticles to improve the properties of aerogels has been investigated in the last few years. In this work, aminated functionalized MXene nanoparticles were successfully prepared as a cross-linking agent as well as an inorganic reinforcing phase, homogeneously embedded in PI aerogels, to synthesize a new PI composite aerogel. The results show that m-MXene can act as a cross-linking point to effectively maintain the network structure, which further improves the dimensional stability and compressive modulus. These PI composite aerogels have a high specific surface area, low density, low shrinkage and excellent mechanical properties.

期刊介绍： Health Services Management Research (HSMR) is an authoritative international peer-reviewed journal which publishes theoretically and empirically rigorous research on questions of enduring interest to health-care organizations and systems throughout the world. Examining the real issues confronting health services management, it provides an independent view and cutting edge evidence-based research to guide policy-making and management decision-making. HSMR aims to be a forum serving an international community of academics and researchers on the one hand and healthcare managers, executives, policymakers and clinicians and all health professionals on the other. HSMR wants to make a substantial contribution to both research and managerial practice, with particular emphasis placed on publishing studies which offer actionable findings and on promoting knowledge mobilisation toward theoretical advances. All papers are expected to be of interest and relevance to an international audience. HSMR aims at enhance communication between academics and practitioners concerned with developing, implementing, and analysing health management issues, reforms and innovations primarily in European health systems and in all countries with developed health systems. Papers can report research undertaken in a single country, but they need to locate and explain their findings in an international context, and in international literature.
