摘要

由于不可生物降解废物的积累，塑料食品包装引起了严重的环境问题。淀粉基生物可降解薄膜由于其丰富性、可生物降解性和可改性性提供了一种可持续的替代方案；然而，它们的实际应用受到其低机械强度和耐水性的限制。将从木质纤维素纤维中提取的纳米纤维素纳入淀粉基质有效地克服了这些限制。纳米纤维素具有高结晶度、优异的机械强度和独特的纤维形态，增强了淀粉基薄膜的结构、屏障和热性能。本文综述了淀粉-纳米纤维素生物复合材料的制备方法、结构和功能特点，以及在食品包装、生物医学器械、环境修复等新兴领域的应用前景。它还指出了当前的研究差距，展示了纳米纤维素增强物如何相对于传统塑料提高性能，并强调了开发可持续、高性能和生态友好型生物复合材料的未来方向。

Revolutionizing thermoplastic starch: advances in nanocellulose reinforced biocomposites: a review

Plastic-based food packaging has raised significant environmental concerns due to the accumulation of non-biodegradable waste. Starch-based biodegradable films offer a sustainable alternative due to their abundance, biodegradability, and modifiability; however, their practical applications are limited by their low mechanical strength and water resistance. Incorporating nanocellulose, derived from lignocellulosic fibers, into starch matrices effectively overcomes these limitations. Nanocellulose provides high crystallinity, exceptional mechanical strength, and a unique fibrillar morphology, enhancing the structural, barrier, and thermal properties of starch-based films. This review presents a comprehensive overview of starch–nanocellulose biocomposites, including preparation methods, structural and functional characteristics, and potential applications in food packaging, biomedical devices, environmental remediation, and other emerging areas. It also identifies current research gaps, demonstrates how nanocellulose reinforcement improves performance relative to conventional plastics, and highlights future directions for developing sustainable, high-performance, and eco-friendly biocomposites.

期刊介绍： Biomass & Bioenergy is an international journal publishing original research papers and short communications, review articles and case studies on biological resources, chemical and biological processes, and biomass products for new renewable sources of energy and materials. The scope of the journal extends to the environmental, management and economic aspects of biomass and bioenergy. Key areas covered by the journal: • Biomass: sources, energy crop production processes, genetic improvements, composition. Please note that research on these biomass subjects must be linked directly to bioenergy generation. • Biological Residues: residues/rests from agricultural production, forestry and plantations (palm, sugar etc), processing industries, and municipal sources (MSW). Papers on the use of biomass residues through innovative processes/technological novelty and/or consideration of feedstock/system sustainability (or unsustainability) are welcomed. However waste treatment processes and pollution control or mitigation which are only tangentially related to bioenergy are not in the scope of the journal, as they are more suited to publications in the environmental arena. Papers that describe conventional waste streams (ie well described in existing literature) that do not empirically address ''new'' added value from the process are not suitable for submission to the journal. • Bioenergy Processes: fermentations, thermochemical conversions, liquid and gaseous fuels, and petrochemical substitutes • Bioenergy Utilization: direct combustion, gasification, electricity production, chemical processes, and by-product remediation • Biomass and the Environment: carbon cycle, the net energy efficiency of bioenergy systems, assessment of sustainability, and biodiversity issues.
