Thermoplastic semi-crystalline polyimides R-BAPB in the powder form were synthesized on the basis of dianhydride R (1,3-bis-(3,3′,4,4′-dicarboxyphenoxy)benzene) and diamine BAPB (4,4′-bis(4″-aminophenoxy) biphenyl) with carbon nanoparticles. The fibers based on R-BAPB modified with carbon nanoparticles were processed by melt technology. The effect of carbon nanoparticles on the crystallization process of the polyimide fibers was studied. Using scanning electron microscopy and differential scanning calometry, an influence of carbon nanoparticles on the structure and crystallization rate of polyimide fibers was investigated. The mechanical properties of R-BAPB fibers modified by carbon nanoparticles in both amorphous and crystallized states were determined. [ABSTRACT FROM AUTHOR] |
