Developing robust and biodegradable biopolymer films based on macroalgae is a challenging task because of its inadequate mechanical strength and poor moisture barrier attribute to its hydrophilic nature. A promising and sustainable approach to overcome this challenge is to reinforce the biopolymer film with polysaccharide microfibre (microcrystalline cellulose) derived from bamboo (GL-MCC). macroalgae were used for the development of biopolymer films without further extraction and purification, which was considered economical and easy. The mechanical, water contact angle (WCA), water absorption capacity (WSC), and thermal behaviour of macroalgae-based biopolymer films revealed that the inclusions of GL-MCC significantly enhanced the durability, moisture barrier, and thermal stability of the biopolymer films. The enhancement is ascribed to the interaction between macroalgae and GL-MCC due to high compatibility. Moreover, the incorporation of GL-MCC successfully increased the rigidity of the macroalgae-based biopolymer films against microorganism and moisture attack, but remain biodegradable and environmental-friendly. The developed biodegradable macroalgae/GL-MCC biopolymer films can potentially be used as packaging materials.
基于大型海藻开发坚固且可生物降解的生物聚合物薄膜是一项具有挑战性的任务，因为其机械强度不足且由于亲水性导致防潮性能较差。克服这一挑战的一种有前景且可持续的方法是用源自竹子的多糖微纤维（微晶纤维素，GL-MCC）增强生物聚合物薄膜。大型海藻未经进一步提取和纯化就用于生物聚合物薄膜的开发，这被认为既经济又简便。基于大型海藻的生物聚合物薄膜的机械性能、水接触角（WCA）、吸水能力（WSC）和热行为表明，GL-MCC的加入显著提高了生物聚合物薄膜的耐久性、防潮性和热稳定性。这种增强归因于大型海藻与GL-MCC之间由于高度相容性而产生的相互作用。此外，GL-MCC的加入成功提高了基于大型海藻的生物聚合物薄膜抵抗微生物和水分侵蚀的刚性，但仍可生物降解且环保。所开发的可生物降解的大型海藻/GL-MCC生物聚合物薄膜有潜力用作包装材料。
