Abstract

Petroleum-derived plastics are harmful to ecosystems because they are not decomposed in the natural environment. Therefore, the replacement of petroleum-derived plastics with biodegradable plastics has attracted considerable attention. UV-barrier films in the agricultural and packaging fields are mainly composed of petroleum-derived plastics, which have a negative impact on the ecosystem when they leak into the environment. Thermoplastic starch (TPS) is an inexpensive and sustainable biodegradable plastic that has recently attracted considerable attention. In this study, the addition of UV barrier properties and remolding ability to TPS for replacing petroleum-derived UV barrier films are investigated. Also, a biodegradable polyester coating is studied to improve the water resistance of the prepared UV-barrier TPS (U-TPS). To prepare U-TPS, a conjugated enamine structure is formed by reacting starch acetoacetate with diamine monomers during melt kneading. U-TPS exhibits high UV barrier properties across the UV regions (200–400 nm) owing to the presence of acetoacetyl groups and enamines. These results indicate the possibility of increasing the utilization of TPS in agriculture and as a packaging material.

轻松制备具有重塑能力和增强防水性的淀粉基紫外线阻隔薄膜

石油衍生塑料在自然环境中无法分解，因此对生态系统有害。因此，用生物降解塑料替代石油衍生塑料已引起广泛关注。农业和包装领域的紫外线阻隔膜主要由石油衍生塑料组成，这些塑料一旦泄漏到环境中，就会对生态系统产生负面影响。热塑性淀粉（TPS）是一种价格低廉且可持续的生物降解塑料，最近引起了广泛关注。在这项研究中，研究了如何在热塑性淀粉中添加紫外线阻隔性能和重塑能力，以取代源自石油的紫外线阻隔膜。此外，还研究了一种可生物降解的聚酯涂层，以提高所制备的紫外线阻隔 TPS（U-TPS）的耐水性。在制备 U-TPS 时，淀粉乙酰乙酸酯与二胺单体在熔融捏合过程中发生反应，形成共轭烯胺结构。由于乙酰乙酰基团和烯胺的存在，U-TPS 在紫外线区域（200-400 纳米）具有很高的紫外线阻隔性能。这些结果表明，有可能提高 TPS 在农业和包装材料中的利用率。
