生物质活性炭改性聚氨酯基复合材料的制备及性能研究
Preparation and Properties Study of Biomass Activated Carbon Modified Polyurethane Matrix Composites
摘要
Abstract
Discarded biomass constitutes an economical and renewable resource,and the activated carbon derived from the biomass boasts several advantageous properties,including a high specific surface area,elevated thermal conductivity,and significant electrical conductivity.These characteristics confer upon it exceptional potential for application within the electrochemical domain.Hazelnut shell activated carbon was successfully prepared by chemical activation of potassium hydroxide(KOH)chemical activation and nitrogen doping.The activated carbon was then integrated into a thermosetting polyurethane(PU)matrix,and its electrochemical behavior,thermodynamic attributes,and microstructural characteristics were analyzed by electrochemical workstation,differential scanning calorimetry,scanning electron microscopy,Raman spectroscopy,X-ray diffraction,and BET.The results showed that nitrogen-doped hazelnut shell activated carbon(HSAC)has a three-dimensional porous structure with an average pore size of less than 6 nm,and it has good dispersibility in PU matrix.The HSAC/PU composites has good thermal stability and exhibits superior electrochemical performance in a 6 mol/L KOH electrolytic environment.At a current density of 0.5 A/g,the HSAC/PU-0.5 has a specific capacitance of 187.6 F/g with excellent rate capability(157.6 F/g at 20 A/g)and a capacitance retention of 83.9%.关键词
