Influence of electron beam pre-irradiation on the thermal behaviors of polyacrylonitrile

Influence of processing parameters on the properties of carbon fibres – an overview

“…Those methods were recently reviewed in . All alternative stabilisation approaches focus on reducing the residence times and the energy consumption or reaching higher stabilisations degrees followed by higher carbon yields . With e‐beam induced cyclisation, stabilisation degrees as high as 99 % could be reached .…”

A simple PAN-based fabrication method for microstructured carbon electrodes for organic field-effect transistors

“…After the atmospheric exposure, the remaining free radicals in the cyclic network structure readily react with oxygen in the air; thus, the formation of oxidized cyclic network structures is similar to that of the PAN treated by conventional thermal oxidative stabilization. The resulting oxidized cyclic network structures in the PAN were converted to graphitic carbon ones during carbonization [41,42]. The current-voltage (I-V) curves, electrical conductivity, and work function of the GCMs prepared by the carbonization of PAN microstructures at various temperatures are shown in Fig.…”

Comparison of microwave and conventional heating methods in carbonization of polyacrylonitrile-based stabilized fibers at different temperature measured by an in-situ process temperature control ring

“…For example, oxidative stabilization via consecutive irradiation treatments is regarded as an efficient and fast method to reduce the stabilization time and obtain a high yield of high-quality CFs. The effects of irradiations on the microstructures of PAN fibers via electron beam [2,3] and g-ray [4e6] have been investigated to evaluate the potential application of irradiation technology in producing CFs. Moreover, alternative method for the carbonization process such as microwave heating has also been considered as a more rapid and energy saving method compared with conventional heating [7,8].…”
