Abstract

Achieving simultaneous sustainability and property is a great challenge for current thermally managed composite films. The study proposes to prepare all-biomass derived nanocomposite films with excellent mechanical, thermal, and degradation properties by self-assembling carbon quantum dots (CQDs) and carbon nanosheets (CNSs) from cellulose nanofibers (CNFs). The results showed that the nanocomposite film with CQDs₁@CNSs₁/CF exhibited the best comprehensive properties with thermal conductivity of 0.817 W m^–1 K^–1, tensile strength of 39.60 MPa, elongation at break of 6.26%, tensile modulus of 5.34 GPa, degradation residual rate in water of 86.02%, degradation residual rate in PBS of 66.67%, and degradation residual rate in buried of 52%. The all-biomass derived nanocomposite films regarding the excellent thermal conductivity, biodegradability, and mechanical properties can be available with thermal management and excellent sustainability.

全生物质衍生的纳米复合薄膜

同时实现可持续性和性能是当前热管理复合薄膜的一个巨大挑战。本研究提出利用纤维素纳米纤维（CNFs）自组装碳量子点（CQDs）和碳纳米片（CNSs），制备具有优异力学、热学和降解性能的全生物质纳米复合薄膜。结果表明：CQDs1@CNSs1/CF纳米复合膜综合性能最佳，导热系数为0.817 W m-1 K-1，抗拉强度为39.60 MPa，断裂伸长率为6.26%，拉伸模量为5.34 GPa，水中降解残余率为86.02%，PBS中降解残余率为66.67%，埋地降解残余率为52%。全生物质纳米复合膜具有优异的导热性、生物降解性和力学性能，具有良好的热管理和可持续性。
