  Abstract

Within the realm of sustainable agriculture, there is a growing focus on the development of biodegradable plastic coverings in response to the adverse environmental impact stemming from contamination by fossil-based plastic film. Herein, a function-integrated cellulose-based composite film was innovatively designed for agricultural insulation applications. Lignocellulosic nanofibers (LCNF) and hollow SiO2 microspheres are blended to construct LCNF/SiO2 composite films with multistage nanocavity structures. Meanwhile, the hexadecyltrimethoxysilane modification further promotes the integration of hydrophobic function and the encapsulated function of hollow SiO2 microspheres in the composite film to form the hydrophobic LCNF/SiO2 (H-LCNF/SiO2) composite film. Owing to the small size effect of SiO2 microspheres and the nanocavity structure, the resulting film exhibits a low thermal conductivity (0.07 ± 0.002 W/(m·K)) and excellent optical properties of the UV–Vis transmission with transparency of over 77% (above 600 nm). Furthermore, H-LCNF/SiO2 composite film displays acceptable mechanical properties with tensile strength of 56.03 MPa and elongation at a break of 6.10%, respectively. Notably, the composite film acquires excellent flexibility, water-proofing, water vapor permeability, and biodegradable performances, improving agricultural applications. Therefore, this work provides a lignocellulose-based film with functional integration that differs from traditional agricultural films by constructing a hollow structure to achieve thermal protection, with the advantage of being more energy efficient and environmentally friendly, promising potential applications in agriculture.
