Abstract Carbon nanofibers have the advantages of small fiber diameter and large specific surface area, making them an efficient gas adsorption material. However, carbon nanofibers with enhanced porous properties are often prepared via a complex carbonization and activation process, which is costly and time consuming. In this study, highly porous polyimide (PI) polymethyl methacrylate (PMMA) based flexible carbon nanofibers were directly prepared by one-step carbonization. The PI nanofibers were obtained through co-electrospinning polyamide acid (PAA) and PMMA followed by thermal imidization. The effects of carbonization conditions on the morphological characteristics, physicochemical properties and volatile organic chemicals (VOCs) adsorption performance of flexible PI/PMMA-based carbon nanofibers were systematically analyzed. The results showed that the PI/PMMA-based carbon nanofibers prepared at 1 000 ℃ had the largest specific surface area (1 047.5 m²·g^-1) and pore volume (0.61 cm³·g^-1). The adsorption/desorption kinetics showed that the increase of specific surface area and the number of micropores in PI/PMMA-based carbon nanofibers significantly accelerated the mass transfer rate of toluene during the adsorption/desorption process. The results of static adsorption experiments showed that the adsorption capacity of the prepared PI/PMMA-based carbon nanofibers for toluene was as high as 6.25 mmol·g^-1 at 25 ℃, and the adsorption isotherms were well fitted with Langmuir model. In addition, the PI/PMMA-based carbon nanofibers also had good adsorption performance for various other typical VOCs such as benzene, acetone, chloroform and methanol. The adsorption capacity for 1 137 mg·m^-3 toluene analyzed via dynamic adsorption was as high as 2.97 mmol·g^-1. After 5 cycles of adsorption and desorption, the adsorption capacity remained at 91%, indicating an excellent cycle stability. This flexible PI/PMMA-based carbon nanofibers with excellent VOCs adsorption performance are promising for the removal of low concentration VOCs.
