摘要

本研究探讨了通过加入甘油作为增塑剂,柠檬酸和氧化锌作为交联剂来增强可生物降解明胶薄膜。结果表明,在溶解度、溶胀性、厚度、pH值、生物降解性以及机械和热特性等方面都有显著改善。在280 ~ 480 nm范围内具有完全的水溶性和紫外-可见光吸光度。土壤掩埋试验表明,在15天内逐渐失重,导致完全降解。通过FTIR和TGA的结构和热分析证实了膜的完整性和稳定性。此外,该研究还强调了这些改性薄膜在酸性溶液中吸附铜(II)离子的有效性,展示了它们在重金属修复等环境应用方面的潜力。这些发现强调了定制添加剂组合的潜力,以生产具有增强性能和功能的可生物降解薄膜。

Tailoring Gelatin Films: Functionality, Stability, and Beyond Biodegradability

Tailoring Gelatin Films: Functionality, Stability, and Beyond Biodegradability

This study investigates the enhancement of biodegradable gelatin films through the incorporation of glycerol as a plasticizer, and citric acid and zinc oxide as cross-linkers. The results showed notable improvements in various properties, including solubility, swelling behavior, thickness, pH, biodegradability, and both mechanical and thermal characteristics. The films demonstrated complete water solubility and UV–visible light absorbance in the 280–480 nm range. Soil burial tests indicated gradual weight loss over 15 days, leading to complete degradation. Structural and thermal analyses via FTIR and TGA confirmed the films' integrity and stability. Additionally, the study highlighted the effectiveness of these modified films in adsorbing copper (II) ions from acidic solutions, showcasing their potential for environmental applications like heavy metal remediation. These findings emphasize the potential of tailored additive combinations to produce biodegradable films with enhanced properties and functionality.
