Quaternary copolymerized polyimides and negative photosensitive polyimide: preparation and properties
Photosensitive polyimide (PSPI) have been developed base on polyimide (PI). PSPI can be used as insulating and protective materials in the microelectronics industry due to the excellent insulating properties, thermal stability, and chemical stability. In this work, we designed a synthetic method to improve the regularity of the polymer chain segment sequence. Quaternary block copolymerized precursors were prepared using condensation polymerization of poly (acid amid). A photosensitive poly (acid amid) salts (co-PAS) was also synthesized to produce patterns with photochemical reaction. After imidization, the resolution of copolymerized PSPI (co-PSPI) pattern was in the range of 16 μm–110 μm. Partial photoreactive cross-linking structure was maintained to improve the thermal stability of co-PSPI. The co-PSPI exhibited higher glass transition temperatures (327.0°C–358.8°C) than copolymerized PI (307.4°C–332.9°C). This work provides the study on the synthesis and properties of quaternary copolymerized PI and PSPI.
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.
