通过酸碱处理与机械处理相结合的方法从木粉中提取出高长径比纳米纤维素,再利用真空过滤的方法制备高强度透明纳米纤维素膜。纳米纤维素的直径主要分布在30~100nm之间,纳米纤维素膜的拉伸强度高达101.79MPa,弹性模量高达5741MPa,透过率高达86.9%。
A method used mechanochemical treatment to obtain cellulose from poplar. The high strength transparent nano cellulose film was further processed by vacuum filter. The cellulose was mainly range between 30-100 nm, tensile strength was reached up to 101.79 MPa, and elastic modulus was reached up to 5 741 MPa and the transparency reached up to 86.9%.
