  环保问题越来越严峻,因此可降解塑料等环保材料遭到更多的关注。那么,可降解颗粒有哪些?

  Environmental protection is becoming more and more serious, so more and more attention has been paid to degradable plastics and other environmental protection materials. So, what are the degradable particles?
  PLA:聚乳酸。是一种新型的生物基及可生物降解材料,运用可再生的植物资源(如玉米)所提出的淀粉原料制成。淀粉原料经由糖化得到葡萄糖,再由葡萄糖及一定的菌种发酵制成高纯度的乳酸,再经过化学合成办法合成一定分子量的聚乳酸。其具有良好的生物可降解性,运用后能被自然界中微生物在特定条件下完整降解,更终生成二氧化碳和水,不污染环境,这对维护环境十分有利,是公认的环境友好材料。
  PLA: polylactic acid. It is a new type of bio based and biodegradable material, which is made of starch material proposed by renewable plant resources (such as corn). Glucose was obtained from starch by saccharification, then high-purity lactic acid was produced by fermentation of glucose and certain strains, and then polylactic acid with certain molecular weight was synthesized by chemical synthesis. It has good biodegradability and can be completely degraded by microorganisms in the nature under specific conditions after use, and finally generate carbon dioxide and water without polluting the environment, which is very beneficial to the maintenance of the environment and is recognized as environmentally friendly materials.

  PBS:聚丁二酸丁二醇酯。白色颗粒,由丁二酸和丁二醇经缩合聚合合成而得,树脂呈乳白色,无臭无味,易被自然界的多种微生物或动植物体内的酶合成、代谢,更终合成为二氧化碳和水,是典型的可完整生物降解聚合物材料。具有良好的生物相容性和生物可吸收性,耐热性能好,热变形温度和制品运用温度能够超越100℃。其合成原料来源既能够是石油资源,也能够经过生物资源发酵得到,PBS是生物降解塑料材料中的佼佼者。
  PBS: polybutylene succinate. White particles are synthesized by condensation polymerization of succinic acid and butanediol. The resin is milky white, odorless and tasteless. It is easy to be synthesized and metabolized by various microorganisms or animals and plants in nature, and finally synthesized into carbon dioxide and water. It is a typical complete biodegradable polymer material. It has good biocompatibility, bioabsorbability, good heat resistance, and the heat deformation temperature and product application temperature can exceed 100 ℃. Its synthetic raw materials can be obtained not only from petroleum resources, but also from fermentation of biological resources. PBS is one of the best biodegradable plastic materials.
  PCL:聚己内酯。具有良好的生物降解性、生物相容性和无毒性,而被普遍用作医用生物降解材料及药物控制释放体系,可运用于组织工程曾经作为药物缓释系统。
  PCL: polycaprolactone. It has good biodegradation, biocompatibility and nontoxicity, and is widely used as medical biodegradable materials and drug controlled release system. It can be used in tissue engineering as drug release system.
  PHA:聚羟基脂肪酸酯。是由很多细菌合成的一种胞内聚酯,在生物体内主要是作为碳源和能源的贮藏性物质而存在,它具有相似于合成塑料的物化特性及合成塑料所不具备的生物可降解性、生物相容性、光学活性、压电性、气体相隔性等许多优秀性能。聚羟基脂肪酸酯在可生物降解的包装材料、组织工程材料、缓释材料、电学材料以及医疗材料方面有宽广的应用前景,但只要降低PHA 的消费本钱后才可能大范围应用。
  PHA: polyhydroxyfatty acid ester. It is a kind of intracellular polyester synthesized by many bacteria. It exists mainly as a storage material of carbon source and energy in organism. It has many excellent properties, such as the physical and chemical characteristics similar to synthetic plastics and biodegradability, biocompatibility, optical activity, piezoelectricity, gas separation and so on, which are not possessed by synthetic plastics. Polyhydroxyfatty acid esters have broad application prospects in biodegradable packaging materials, tissue engineering materials, slow-release materials, electrical materials and medical materials, but they can be widely used only after reducing the consumption cost of PHA.
  PBAT:聚己二酸/对苯二甲酸丁二酯。PBAT属于热塑性生物降解塑料,是己二酸丁二醇酯和对苯二甲酸丁二醇酯的共聚物,兼具PBA和PBT的特性,既有较好的延展性和断裂伸长率,也有较好的耐热性和冲击性能;此外,还具有优秀的生物降解性,是目前生物降解塑料研讨中十分活泼和市场应用更好降解材料之一。
  PBAT: poly (adipic acid) / butylene terephthalate. PBAT is a thermoplastic biodegradable plastic, which is a copolymer of butylene adipate and butylene terephthalate. It has the characteristics of PBA and PBT. It has good ductility and elongation at break, as well as good heat resistance and impact performance. In addition, it also has excellent biodegradability. It is the most active and the best degradation material in the market in the current research of biodegradable plastics. One of.
