The current environmental issues caused by the massive consumption of oil-based materials are boosting the efforts to develop novel eco-friendly and biodegradable materials. In this context, this work presents the preparation of waterborne latexes composed of hybrid casein/acrylate nanoparticles containing tannic acid, a plant-derived phenolic compound, which is proposed as cross linker agent during film formation. In this way, self-crosslinkable formulations containing variable amounts of cross linker were prepared. This proposal allows extending the properties of hybrid casein/acrylate films by improving their water resistance, without degrading their mechanical strength, and providing them excellent UV-blocking properties. These results show that a latex with a high bio-content, as hybrid casein/acrylate one, in combination with a plant-derived phenolic compound as cross linker could pave the way for producing self-crosslinkable formulations with potential to be applied as more eco-friendly films with improved biodegradability.

当前由大量消耗油基材料引起的环境问题正在推动开发新型环保和可生物降解材料的努力。在此背景下，这项工作介绍了水性乳胶的制备，该乳胶由含有单宁酸的混合酪蛋白/丙烯酸酯纳米粒子组成，单宁酸是一种植物来源的酚类化合物，被提议作为成膜过程中的交联剂。以此方式，制备了含有可变量交联剂的可自交联制剂。该提议允许通过提高其耐水性而不降低其机械强度来扩展混合酪蛋白/丙烯酸酯薄膜的性能，并为它们提供出色的紫外线阻挡性能。这些结果表明，具有高生物含量的乳胶，如混合酪蛋白/丙烯酸酯，
