Abstract

The demand for sustainable packaging materials is rapidly increasing due to growing environmental concerns over the impact of plastic waste. In this study, biodegradable, porous, lightweight, and high-surface-area microcrystalline cellulose-starch (MCC-S) hybrid aerogels were synthesized via supercritical carbon dioxide (SC-CO) drying. The samples were generated using five different MCC-S weight ratios and characterized for their morphology, crystallinity, and structural and thermal properties. When MCC and S were used together, aerogels with superior properties were obtained compared to those made from each component individually. Specifically, the 1:2 MCC-S aerogel exhibited the highest porosity (97%), the lowest density (0.058 g/cm), and the lowest thermal conductivity (0.012 W/(m·K)) along with a high specific surface area (258 m/g). Therefore, MCC-S aerogels are promising insulators for advanced packaging applications, potentially serving as a sustainable alternative to Styrofoam.

摘要

由于对塑料垃圾影响的环境问题日益关注，对可持续包装材料的需求正在迅速增加。在本研究中，通过超临界二氧化碳（SC-CO）干燥合成了可生物降解、多孔、轻质且高比表面积的微晶纤维素-淀粉（MCC-S）混合气凝胶。使用五种不同的MCC-S重量比制备样品，并对其形态、结晶度以及结构和热性能进行表征。当MCC和S一起使用时，与单独由每种组分制成的气凝胶相比，获得了具有优异性能的气凝胶。具体而言，1:2的MCC-S气凝胶表现出最高的孔隙率（97%）、最低的密度（0.058 g/cm）和最低的热导率（0.012 W/(m·K)）以及高比表面积（258 m/g）。因此，MCC-S气凝胶是用于先进包装应用的有前途的绝缘体，有可能作为聚苯乙烯泡沫塑料的可持续替代品。
