  聚苯并恶唑基气体分离膜的制备与性能：聚羟基酰亚胺热重排与聚羟基酰胺热环脱水的比较研究

  摘要：

  这项比较研究的重点是聚（羟基酰胺）（PHA）的环脱水反应和芳族聚（羟基酰亚胺）（API）的热重排（TR）反应，以生产用作气体分离膜的聚苯并恶唑（PBO）。两种途径之间的系统比较表明，PHA环化脱水可在比API-TR途径低100℃以上的温度下产生完全转化的PBO膜。PHA-PBO的气体分离性能可与API-TR聚合物相媲美，而PHA-PBO的机械稳定性更强。更重要的是，通过PHA环化脱水途径，可以在空气和惰性气氛中同样良好地生产PBO薄膜。在空气中形成的PHA-PBO在统计学上与在N 2中形成的PHA–PBO具有相同的物理和运输性质。本研究提供了有关PHA到PBO环脱水过程的基本信息。

  This comparative study focuses on the cyclodehydration reaction of poly(hydroxyamide)s (PHAs) and the thermal rearrangement (TR) reaction of aromatic poly(hydroxyimide)s (APIs) to produce polybenzoxazoles (PBOs) for application as gas separation membranes. Systematic comparisons between the two routes showed that PHA cyclodehydration can produce fully converted PBO membranes at a temperature more than

  A new chemically modified graphene was prepared using carboxylated graphene oxide (GO) and fluorinated poly(hydroxyamide) (6FPHA), the latter is the precursor of fluorinated poly(benzobisoxazole) (6FPBO). The results showed that, unlike common GO, which can only be dispersed in water under neutral or basic conditions, the RGO–6FPBO (reduced graphene oxide–6FPBO) could be stably dispersed in Lewis acids. The RGO–6FPBO–poly(benzobisoxazole) (PBO) composite was achieved by simple solution blending of RGO–6FPBO and PBO in methanesulfonic acid. The obtained RGO–6FPBO–PBO composite films exhibited a dramatic increase in electrical conductivity, by 8 orders of magnitude at the RGO–6FPBO content of 4 wt%, without significantly sacrificing optical transparency. When the content of RGO–6FPBO was higher than 4 wt%, the dielectric constant of the composite film also increased remarkably. The mechanical properties and thermal stability of the composite were also improved by the incorporation of RGO–6FPBO.

  利用羧基氧化石墨烯（GO）和氟化聚（羟基酰胺）（6FPHA）制备了一种新型化学修饰石墨烯，后者是氟化聚（苯并异噁唑）（6FPBO）的前体。结果表明，普通 GO 只能在中性或碱性条件下分散在水中，而 RGOâ6FPBO （还原型氧化石墨烯-6FPBO）则不同，可以稳定地分散在路易斯酸中。通过将 RGOâ6FPBO 和 PBO 在甲磺酸中进行简单的溶液混合，得到了 RGOâ6FPBOâ 聚（苯并异噁唑）（PBO）复合材料。在 RGOâ6FPBO 含量为 4 wt% 时，所得到的 RGOâ6FPBOâPBO 复合薄膜的导电性能显著提高了 8 个数量级，而光学透明度却没有明显下降。当 RGOâ6FPBO 的含量高于 4 wt% 时，复合薄膜的介电常数也显著增加。RGOâ6FPBO 的加入还改善了复合材料的机械性能和热稳定性。

  A series of high‐performance polymer/carbon nanotube (CNT) composites with different nanotube contents have been prepared via condensation of N‐silylated diamino terminated precursor of the polymer with acid chloride‐functionalized CNTs and subsequent thermal cyclodehydration. The composites have been fully characterized by infrared and Raman spectroscopy, electron microscopy, and thermal analysis

  通过将聚合物的N-甲硅烷基化的二氨基封端的前体与酰氯官能化的CNT缩合，然后进行热环脱水，制备了一系列具有不同纳米管含量的高性能聚合物/碳纳米管（CNT）复合材料。该复合材料已通过红外和拉曼光谱，电子显微镜和热分析进行了充分表征。由于聚合物的共价连接，已在复合物中观察到了各种有趣的形态特征，包括螺旋结构。包含CNT的情况下，复合材料具有出色的热稳定性，介电常数和机械强度也得到了显着提高。©2012 Wiley Periodicals，Inc. J Polym Sci A部分：Polym Chem，2012年
• Synthesis and Characterization of Poly(hydroxyamide-benzoxazole) Multi-Block Copolymers

  Poly(hydroxyamide-benzoxazole) multi-block copolymers were prepared from the polymerization of 2,2'-bis(3-amino-4-hydroxyphenyl)-hexafluoropropane (6FAP) and 4,4'-oxydibenzoyl chloride (ODBC). N,O-bis(trimethylsilyl)trifluoroacetamide (BSTFA) or N,O-bis(trimethylsilyl)acetamide (BSA) was used as a silylation agent to activate amine functional groups. The amine terminated hydroxyamide prepolymers (ATHA) were synthesized by employing the low temperature solution polymerization via the in situ silylation method. p-Toluenesulfonic acid was added into the reaction mixture of ATHA, which in turn followed by cyclodehydration at 150 similar to 190 degrees C 4 for 24hrs to produce amine terminated benzoxazole oligomers (ATBO). Finally, the poly(hydroxyamide-benzoxazole) multi-block copolymers were prepared from the condensation of ATHA, ATBO and ODBC by employing the silylation method at relatively low temperature of 60 degrees C. In the present work, properties of multi-block copolymers have been investigated.

  Polybenzoxazoles (PBOs), such as thermally rearranged (TR) polymers, have been shown to have excellent gas separation performance. Herein we report the preparation and transport properties of two new series of PBO-based polymers that were thermally derived from triptycene-containing o-hydroxy polyimide and polyamide precursors via a thermal rearrangement (TR) process and a thermal cyclodehydration (TC) process

  聚苯并恶唑（PBO），例如热重排（TR）聚合物，已显示具有出色的气体分离性能。本文中，我们报告了两种新的基于PBO的新系列聚合物的制备和传输性能，这些聚合物是通过含三萜烯的邻羟基聚酰亚胺和聚酰胺前体通过热衍生而来的热重排（TR）过程和热环脱水（TC）过程。将三茂萜单元掺入聚（羟基酰亚胺）前体结构中导致分数自由体积的显着增加，并在转化的基于PBO的TR聚合物中产生了超细微孔，从而实现了高气体渗透性和高选择性。尽管与TR方法相比，聚（羟酰胺）前体的TC方法导致所得的含三茂茂的PBO聚合物的分离性能有所改善，但PBO膜通过TC工艺显示出优异的机械性能，优于先前在文献中报道的许多其他TR聚合物以及本研究中的含三茂铁的TR聚合物。尤其是，在450°C下热重排的PBO膜的H 2纯气体渗透率是810 barrer，CO 2渗透率是270 barrer，CO 2 / CH 4和H 2 / CH 4的选择性分别为67和200。
