Abstract: With the scale development of industries such as food, leather, and textiles, a large amount of biomass waste has been produced, resulting in serious resource waste and environmental pollution. Extracting gelatin from these biomass wastes to develop bionic, lightweight, and durable smart materials has become the key to solving this problem and promoting sustainable development. Gelatin is a kind of polymer composed of linear polypeptides. As a hydrophilic material, gelatin shows strong self-assembly ability in aqueous solution. Under certain conditions (tempe-rature, ionic strength, pH value, etc.), gelatin molecules have enough flexibility to present a variety of conformations. Structural flexibility and adjustability of gelatin create conditions for the development of gelatin-based smart materials. Due to the unique amino acid sequence and biocompatibility of gelatin, the research and development of multifunctional gelatin-based materials has become a hotspot through molecular structure design and performance optimization. Firstly, the composition of gelatin and its structural characteristics are introduced. Then, the development and application status of five kinds of gelatin-based smart materials, such as temperature sensitive material, pH responsive material, humidity sensitive material, salt sensitive material and photosensitive material, are analyzed. The development trend of five types of smart materials is discussed. Finally, the challenges faced and future research direction of gelatin-based smart materials are proposed.
