摘要

从废油脂和山毛榉木杂酚油中提取的芳基和非芳基脂肪酰胺类似物被用作可持续的环氧固化剂,用于生产具有可调机械、热学和抗菌性能的生物基热固性共聚物。这些共聚物的热挠曲温度和刚度随其芳化比的增加而增加;然而,它们的抗拉强度和抗菌效力在中档达到最大。引人注目的是,不管它们的芳基化比例如何,所有这些脂肪基共聚物都能承受高达300°C的温度,并能均匀地与天然织物(如棉花)结合,使其防水。这些理想的特性和可调的特性为再生脂肪、油和油脂(FOGs)在增值产品生产中的利用开辟了各种可能性,包括但不限于耐污或自清洁个人防护设备和表面涂层、不粘抗菌伤口敷料或绷带、电气防水填料或密封剂,以及许多类型的复合材料。

Waste Grease to Tunable Biobased Copolymers: Brown Grease Fatty Amide Analogs as Antibacterial Epoxy Curing Agents

Arylated and non-arylated fatty amide analogs derived from waste grease and beechwood creosote are utilized as sustainable epoxy curing agents to produce biobased thermosetting copolymers with tunable mechanical, thermal, and antibacterial properties. The heat deflection temperature and stiffness of these copolymers increase with their arylation ratio; however, their tensile strength and antibacterial potency maximize at the mid-range. Strikingly, regardless of their arylation ratio, all these fat-based copolymers endure temperatures as high as 300 °C and uniformly bind to natural fabrics, e.g., cotton, making them waterproof. These desirable features and tunable properties open various possibilities for the utilization of recycled fats, oils, and greases (FOGs) in the production of value-added products, including but not limited to stain-resistant or self-cleaning personal protective equipment and surface coatings, nonstick antimicrobial wound dressings or bandages, fillers or sealants for electrical waterproofing, and numerous types of composites.
