초록

In this study, the carbonized polybenzoxazole (C-PBO) nano-webs were made from PBO nano-web via the electro-spun polyhydroxyamide (PHA) nano-web by heating temperatures of 800-1200 ℃ for 1h under N2 atmosphere, respectively. XPS, EA, FT-IR, TGA, Raman spectra, electrical conductivity, and HR-TEM were used to observe the carbonization behavior in C-PBO nano-webs. XPS, EA, and FT-IR results displayed that PBO nano-web directly converted to C-PBO nano-webs above 800 ℃ without the stabilization process. TGA results showed that the C-PBO nano-webs have excellent thermal stability at high temperatures (~750 ℃) and can undergo the carbonization process to yield turbostratic graphite structure. Raman spectra observed the ID/IG of C-PBO nano-webs was improved on increasing the carbonization temperature.
