浸渍法改性纤维素薄膜制备及其pH响应中的应用
Preparation of Cellulose Film Modified by Impregnation Method and its Application in Environmental Response
摘要
Abstract
Cellulose,as a widely existing biomass material in nature,has advantages such as abundant resources,renewability,and biodegradability.However,its insulation properties limit its application in the field of electronic devices.This article uses filter paper(cellulose film)with different porosity as the substrate,and doped conductive polymer poly(sodium 4-styrene sulfonate)into the filter paper through impregnation method to prepare conductive composite films.The mechanical properties,crystalline structure,thermal stability,and electrical conductivity of the thin film were tested and they were applied in pH responsive materials.The influence of different pore sizes and varying amounts of modifying agents on the electrical properties of cellulose conductive films was also explored.The following conclusion were drawn that the impregnation of PSS improved the mechanical properties and thermal stability of the composite film.The PSS/FP film prepared by impregnating FP into 7%PSS solution exhibits excellent conductivity,with a minimum impedance of 8.6×104 Ω,and can quickly and sensitively monitor changes in pH value.The research provides reference and guidance for the further development and application of cellulose modified conductive films.关键词
