低纯度植物油单体衍生的环保塑料及其可持续回收
Eco-plastics Derived from Low Purity Plant Oil Monomer and Their Sustainable Recycling
生物基环保塑料是一类新兴的可持续材料。合成性能优异的聚合物材料通常需要高纯度的生物质单体,然而高纯度单体的生产过程中并不"绿色"。另一方面,为了环境保护,人们迫切的希望塑料可以被回收再利用。在这里,我们提出了一种简单而有效的策略,从低纯度植物油单体设计和制备具有优异性能的聚酯酰胺(PEA),可以作为的生态塑料。选用植物油低纯度的C21 二酸(C21)为主要单体,采用一锅缩聚法合成高性能PEA.所得到的PEA可以像热塑性塑料一样进行重复加工。更重要…查看全部>>
Biobased eco-plastics are an emerging class of sustainable materials.However,the synthesis of mechanically strong polymer materials usually needs high purity monomers derived from biomass,which is not"green"during production.On the other hand,the recycling of plastics is highly desired for environmental protection.Here,we present a robust and facile strategy to design and prepare mechanically strong polyester amides(PEAs)from low-grade plant oils,that can be…查看全部>>
