摘要

为了提供具有高耐热性和超低热膨胀系数 (CTE) 的聚酰亚胺 (PI),以用于柔性显示基板,我们设计并成功合成了一种具有双苯并咪唑和双酰胺基团的新型二胺,即 N,N'-(1H,1'H-[5,5'-联苯并[d]咪唑]-2,2'-二基)双(4-氨基苯甲酰胺) (BZBA)。通过与 3,3',4,4'-联苯四羧酸二酐(BPDA)、4、4'-氧代二邻苯二甲酸酐(ODPA)、3,3',4,4'-联苯四羧酸二酐(BTDA)和 4,4'-(六氟异丙基茚)-二邻苯二甲酸酐(6FDA)分别进行热酰亚胺化制备。其中,BZBA-BPDA 具有较高的玻璃化转变温度(Tg = 345 °C),同时热膨胀系数极低(CTE = 1.9 ppm K-1),符合 OLED 设备中聚合物柔性基板的加工要求。比较了不同二酐对 PBIAIs 性能的影响,为进一步调整 PI 分子结构以满足工业聚合物薄膜的特定要求提供了有意义的参考。

Polyimides with ultra-low coefficient of thermal expansion derived from diamine containing bisbenzimidazole and bisamide
To provide polyimide (PI) with high heat resistance and ultra-low coefficient of thermal expansion (CTE) for use in flexible display substrates, a novel diamine with bisbenzimidazole and bisamide groups, namely N,N'-(1H,1'H-[5,5'-bibenzo[d]imidazole]-2,2'-diyl)bis(4-aminobenzamide) (BZBA), was designed and successfully synthesized. Several poly(benzimidazole-amide-imide) (PBIAI) films were prepared by thermal imidization with 3,3',4,4'-biphenyltetracarboxylic dianhydride (BPDA), 4,4'-oxydiphthalic anhydride (ODPA), 3,3',4,4'-benzophenonetetracarboxylic dianhydride (BTDA), and 4,4'-(hexafluoroisopropylindene)-diphthalic anhydride (6FDA), respectively. Among them, BZBA-BPDA has a high glass transition temperatures ( Tg = 345 °C) while achieving an extremely low coefficients of thermal expansion (CTE = 1.9 ppm K−1), meeting the processing requirements of polymer flexible substrates in OLED devices. The effects of different dianhydrides on the performance of PBIAIs were compared, providing a meaningful reference for further adjusting the PI molecular structure to meet specific requirements for industrial polymer films.

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.
