Polymer of intrinsic microporosity (PIM-1) is characterized by a developed microporous structure. Needle-free Nanospider™ electrospinning of the PIM-1 solution with subsequent pyrolysis either under vacuum or in argon-hydrogen medium (7 vol% H₂) at 900–1200 °C results in PIM-1 based carbon nanofibers (CNF) self-supporting mats. The samples were thoroughly characterized by N₂ and CO₂ adsorption using the BET, BJH, Dubinin-Radushkevich (DR), NLDFT and GCMC methods, CO₂ uptake, and by Raman spectroscopy, elemental analysis, electrical conductivity, SEM. Since the N₂ adsorption is found to be inapplicable, the presence of microporosity in the CNF is confirmed by CO₂ adsorption (273 K) by the DR, NLDFT and GCMC methods. The CNF reach micropore specific surface area of 919 m² g⁻¹, micropore volume of 0.257 cm³ g⁻¹ and CO₂ uptake of 4.01 mmol g⁻¹, which is higher than for initial PIM-1. Pt/PIM-1 CNF self-supporting mat, was successfully tested as anode for HT-PEM fuel cell.

固有微孔聚合物 (PIM-1) 的特征在于发达的微孔结构。PIM-1 溶液的无针 Nanospider™ 静电纺丝，随后在真空下或在氩-氢介质（7 vol% H ₂）中在 900–1200 °C 下热解，产生基于 PIM-1 的碳纳米纤维 (CNF) 自支撑垫。使用 BET、BJH、Dubinin-Radushkevich (DR)、NLDFT 和 GCMC 方法通过 N ₂和 CO _{2吸附、CO 2}吸收以及通过拉曼光谱、元素分析、电导率、SEM 彻底表征样品。由于发现 N ₂吸附不适用，因此通过 CO _{2证实了 CNF 中微孔的存在}通过 DR、NLDFT 和 GCMC 方法吸附 (273 K)。CNF 达到 919 m ²  g ^-1的微孔比表面积、0.257 cm ³  g ^{-1的微孔体积和 4.01 mmol g -1}的CO ₂吸收量，这高于初始 PIM-1。Pt/PIM-1 CNF 自支撑垫作为 HT-PEM 燃料电池的阳极成功测试。
