Abstract
A series of modified aromatic oxadiazole polymers were synthesized via condensation reactions of terephthalic dihydrazide (TPH) and varying amounts of Trimesic acid (H3BTC) in polyphosphoric acid (PPA). Pentaerythritol was introduced to construct intermolecular hydrogen bonds among polymeric chains, resulting in a three-dimensional network structure, and correlations between H-bonds and mechanic properties are discussed. Structures and mechanic properties of the polymers were characterized and analyzed. By investigation of molecular structure and membrane formation process of chemically modified and hydrogen bond-regulated polymer membranes, it was found that the modified polymer membranes retain the unique thermal stability, chemical stability, and good hydrophobicity of the POD rigid polymer. Additionally, hydrogen bonds not only significantly improve the overall quality of the membrane, but also play an important role in enhancing the mechanical properties of the membrane, as demonstrated in the highest observed of up to a maximum of 167.19 MPa. Furthermore, impact of H3BCT modification on light absorption and fluorescence performance of T-PODx is also analyzed and discussed in this paper.
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.
