a Results of elementary analysis of aqPAM-CFs after the carbonisation of PCFs containing PA at various temperatures, and mPAN-CFs after the carbonisation of PCFs at 1000–1400 °C. The PCFs were prepared by the pre-carbonisation of stabilised fibres at 800 °C. b XPS P 2p spectra of aqPAM fibre, aqPMA-SF, and aqPAM-CFs. Black line indicates P 2p signals of aqPAM (a–5, AM/AN (75/25 mol%) containing 2.9 wt% PA) fibre, red line indicates P 2p signals of aqPAM-SF obtained after stabilisation of a–5 fibre at 350 °C for 10 min, yellow line indicates P 2p signals of aqPAM-CF obtained after the carbonisation at 1000–1400 °C of PCFs derived from the aqPAM-SF, blue line indicates the P 2p signals of aqPAM-CF obtained after the carbonisation at 1100–1500 °C of PCFs derived from the aqPAM-SF.
