MXene@聚多巴胺的制备、性能和应用
Preparation,Properties and Application of MXene@Polydopamine
摘要
Abstract
Polydopamine-coated MXene(MXene@PDA),a photothermal conversion material,was introduced into collagen aerogel to improve its photothermal conversion ability and expand its application in the field of low temperature protection.MXene was prepared by chemical etching and in situ lithium-ion intercalation,and then the oxidative self-polymerization reaction of dopamine(DA)on the surface of MXene was utilized to obtain MXene@PDA.Moreover,the effect of DA dosage on the properties of MXene@PDA was explored.The structure and properties of MXene@PDA were tested and characterized using transmission electron microscopy,scanning electron microscopy,X-ray diffraction and ultraviolet-visible-near infrared spectroscopy.Results showed that PDA was successfully coated on the surfaces of MXene flakes,which improved the environmental stability of MXene.The best light absorption performance of the fabricated MXene@PDA was achieved when the mass ratio of MXene to DA was 100:6.Under the irradiation of 100 mW/cm2 xenon lamp,the temperature of MXene@PDA modified collagen aerogel was as high as 54.8 ℃,which was enhanced by 17.9 ℃ compared with pure collagen aerogel,and the maximum temperature was around 54.8 ℃ in several photothermal cycling experiments,showing the excellent photothermal conversion performance and cycling stability.关键词
