Polybenzoxazine (PBZ) based-carbon xerogel derived from bisphenol A, propylamine, and paraformaldehyde has been prepared via a sol-gel technique, using N-Methyl-2-pyrrolidone (NMP) as a solvent and 30 wt% of benzoxazine monomer concentration. A simple exchange with acetone was employed to remove solvent and create pore structure without the need of using a high cost supercritical conditions. After the curing process, the organic xerogel is carbonized at various temperatures between 500-900°C then activated under CO2 atmosphere at 900°C to obtain the carbon xerogel. Various characterization techniques will be performed, namely FTIR, STA-FTIR, DSC, BET, XPS, CHN, and SEM to characterize the properties of polybenzoxazine such as porosity, surface area, surface functionalities and textural properties. It is anticipated that the amine-embedded carbon xerogel from propylamine-derived polybenzoxazine will perform as an excellent adsorbent for CO2 capture due to the enrich amine functionalities and large microporous surface area.
