Poly(acrylonitrile) (PAN) electrospun nanofibres were stabilized at 285°C in surrounded conditions for 1 h and then carbonized at 900°C for 1 h in inert nitrogen (N) at 10 psi. The resulting carbonized PAN nanofibre films were fabricated into square pieces and exposed to several classification procedures. Raman spectroscopy analysis was used to stretch approximately 920 cm−1 of the designated construction of the G-band of the carbonized nanofibres. Energy-dispersive X-ray (EDX) spectroscopy was used to examine the chemical structures and elemental distribution of the carbonized PAN nanofibres. EDX spectroscopy revealed the PAN carbon core at roughly 61%. After annealing, the PAN carbon nanofibres were 89% carbon weight (atomic %), with N and minor quantities of Ni and O. The structure was confirmed by X-ray diffraction for bulk PAN and carbonized PAN nanofibres. Examination of the outcomes may be valuable for improving the use of various smart nanofibre materials in the industry and for water treatment sensor applications.

超疏水电纺聚（丙烯腈）电离纳米纤维智能材料特性的原位退火和表征

聚（丙烯腈）（PAN）电纺纳米纤维在 285°C 下在包围条件下稳定 1 小时，然后在 900°C 下在 10 psi 的惰性氮气（N）中碳化 1 小时。将所得碳化 PAN 纳米纤维薄膜制成方形片并进行多种分类程序。拉曼光谱分析用于拉伸碳化纳米纤维的 G 带指定结构的约 920 cm-1。能量色散 X 射线 (EDX) 光谱用于检查碳化 PAN 纳米纤维的化学结构和元素分布。EDX 光谱显示大约 61% 的 PAN 碳核。退火后，PAN 碳纳米纤维的碳重量为 89%（原子百分比），含有 N 和少量的 Ni 和 O。该结构通过块状 PAN 和碳化 PAN 纳米纤维的 X 射线衍射证实。对结果的检查对于改进工业中各种智能纳米纤维材料的使用和水处理传感器应用可能很有价值。
