The Preparation of Nanocellulose Films and the Impact of Their Surface Nano/micro-scale Structuring on Performance
摘要
Abstract
Composite films of cellulose nanofibrils(CNF)and cellulose nanocrystals(CNC)were prepared using the doctor blade method.By introducing different types of templates,nano-and micro-scale structures were successfully constructed on the surface of the composite films.The resulting films were systematically characterized using field emission scanning electron microscopy(FE-SEM),atomic force microscopy(AFM),Fourier transform infrared spectroscopy(FT-IR),X-ray diffraction(XRD),ultraviolet analysis,a universal tensile testing machine,and a contact angle analyzer.The results indicated that the selected templates did not significantly affect the crystalline structure of cellulose or its characteristic infrared peaks,but they effectively constructed nano-or micro-scale structures on the surface of the composite films.Additionally,the structural treatment significantly enhanced the plasticity of the composite films(with a maximum increase in elongation of 15%)and tensile strength(with a maximum improvement of 10 MPa).Further studies also revealed that structures of different sizes had a differentiated impact on the hydrophilicity and hydrophobicity of the composite films.This research provides new insights into the surface structuring of cellulose-based composite films and their application in high-performance materials.关键词
