AB  - Protection of intrinsically brittle quartz chromatographic columns (CCs) from 
      breakage or property deterioration in gas chromatography (GC) analysis has become 
      an important research topic regarding high-temperature GC techniques. Polyimide 
      (PI) has proved to be the most suitable protective coating for quartz CCs. In the 
      current research, a series of novel high-temperature-resistant PI coatings for 
      quartz CCs operated over 320  degrees C have been successfully prepared. For this 
      purpose, the aromatic diamine with a rigid skeleton structure 
      2-(4-aminophenyl)-5-aminobenzimidazole (APBI) was copolymerized with two aromatic 
      dianhydrides-3,3',4,4'-benzophenotetracarboxylic acid dianhydride (BTDA) and 
      4,4'-oxydiphthalic anhydride (ODPA)-and an aromatic diamine with flexible ether 
      linkages-4,4'-oxydianiline (ODA)-by a two-step polymerization procedure via 
      soluble poly(amic acid) (PAA) precursors, followed by thermal imidization at 
      elevated temperatures. The developed PI coatings exhibited good comprehensive 
      properties, including glass transition temperatures (T(g)) as high as 346.9  degrees C, 
      measured by dynamic mechanical analysis (DMA), and coefficients of linear thermal 
      expansion (CTEs) as low as 24.6 x 10(-6)/K in the range of 50-300  degrees C. In 
      addition, the PI coatings exhibited good adhesion to the fused quartz capillary 
      columns. No cracking, delamination, warpage, or other failures occurred during 
      the 100-cycle thermal shock test in the range of 25-320  degrees C.
