Inspired by the superhydrophobic characteristics of duck feathers this research introduced an intelligent, responsive, and eco-friendly food packaging film constructed from carboxymethyl cellulose (CMC) and gelatin (Gel). The film successfully mimics the asymmetric, bionic, barbed structure of a duck feather, offering outstanding hydrophobicity and moisture vapor resistance characteristics. Moreover, the bionic film demonstrated good mechanical strength, film-forming ability and biodegradability. In addition, resveratrol (Res) was integrated into the CMC/Gel matrix, endowing the film with excellent antibacterial, antioxidant, pH-sensitive, fluorescent, and UV shielding properties. The film also exhibited UV-induced photochromic behavior and antifatigue food anti-counterfeiting capabilities. Furthermore, the film enables swift, sensitive, and real-time visual tracking of food spoilage under natural daylight conditions. In beef preservation applications, the developed film packaging can extend the shelf-life of beef to five days, two days longer than that of conventional polyethylene packaging. Therefore, the bionic intelligent active packaging engineered in this study offers promising guidelines for the design of eco-friendly and efficient consumable containment solutions.
受鸭毛超疏水特性的启发，本研究引入了一种由羧甲基纤维素（CMC）和明胶（Gel）构建的智能、响应性和环保型食品包装薄膜。该薄膜成功模拟了鸭毛的不对称、仿生、带刺结构，具有出色的疏水性和防潮气透过性。此外，仿生薄膜表现出良好的机械强度、成膜能力和生物降解性。此外，白藜芦醇（Res）被整合到CMC/Gel基质中，使薄膜具有优异的抗菌、抗氧化、pH敏感、荧光和紫外线屏蔽性能。该薄膜还表现出紫外线诱导的光致变色行为和抗疲劳食品防伪能力。此外，该薄膜能够在自然日光条件下对食品变质进行快速、灵敏和实时的视觉跟踪。在牛肉保鲜应用中，所开发的薄膜包装可将牛肉的保质期延长至五天，比传统聚乙烯包装长两天。因此，本研究中设计的仿生智能活性包装为环保和高效的可消耗包装解决方案的设计提供了有前景的指导方针。
