一种纤维素基导电稳定柔性薄膜的制备及性能研究
Preparation and Properties of a Cellulose-based Flexible Film with Conductive Stability
摘要
Abstract
Dopamine molecules were introduced onto the surface of cellulose nanofibers(CNF)through amidation reaction,resulting in dopamine-modified cellulose nanofibers(DCF).High-transparency DCF/montmorillonite(MMT)film materials were prepared by combining DCF with MMT.Silver nanowires(AgNWs)and graphene oxide(GO)were further deposited on the film through vacuum filtration to prepare cellulose-based transparent conductive films.The test results showed that the grafting of dopamine molecules did not affect the morphology and crystalline structure of CNF.The prepared DCF/MMT film maintained a hightransmittance(82.4%)and exhibited a tensile strength of 49.5 MPa at a relative humidity of 100%,which was a 64%improvement compared to that of CNF/MMT film.The conductive films assembled with this material exhibited good transparency,conductivity,and electrical stability.The DCF/MMT/AgNWs/GO(DMAG)film demonstrated stable high conductivity after water immersion or exposure to high humidity(relative humidity of 90%),with the sheet resistances of 32 and38 Ω,respectively.The preparation of this conductive film provides a new approach for the assembly of transparent electronic devices.关键词
