生物降解颗粒作为良好的材料与基体树脂密切相关！

随着人们对材料性能要求的不断提高，可降解颗粒材料的潜在市场和主要需求增长动力。其中，生物降解的物理力学性能得到了很好的改善。为什么会说生物降解颗粒作为良好的材料与基体树脂密切相关？

With the continuous improvement of people's requirements for material properties, the potential market and main demand growth power of degradable granular materials. Among them, the physical and mechanical properties of biodegradation have been well improved. Why is it said that biodegradable particles are closely related to matrix resin as a good material?

可生物降解的无机颗粒粒径足够小，颗粒之间的界面结合良好，无机颗粒像刚性链一样在聚合物中起到增强作用，这种分散状态有很好的效果。胶体二氧化硅和炭黑对橡胶有补强作用的重要原因之一是它们在橡胶中形成了这种二聚结构。

The particle size of biodegradable inorganic particles is small enough, and the interface between particles is well combined. Inorganic particles play a reinforcing role in polymers like rigid chains. This dispersion state has a good effect. One of the important reasons why colloidal silica and carbon black have reinforcing effect on rubber is that they form this dimer structure in rubber.

无机颗粒以随机分散状态存在，有的聚集成簇，有的以单独的分散形式存在。这种分散状态既不会增强也不会变韧。因为粉体中颗粒之间的相互作用很弱，会成为填充材料中较弱的环节。无机颗粒均匀且单独地分散在基体树脂中。

Inorganic particles exist in a random dispersion state, some are clustered, and some exist in a separate dispersion form. This dispersion will neither strengthen nor toughen. Because the interaction between particles in the powder is very weak, it will become a weak link in the filling material. The inorganic particles are uniformly and separately dispersed in the matrix resin.

在这种情况下，无论颗粒与基体树脂之间是否存在良好的界面结合，都会产生一定的补强增韧效果。生物降解促进了工程塑化的进程，使其发挥着越来越重要的作用。可生物降解颗粒是具有改进的阻燃性、强度、抗冲击性、韧性等性能的塑料制品。

In this case, whether there is a good interface between particles and matrix resin or not, it will produce a certain reinforcement and toughening effect. Biodegradation promotes the process of Engineering plasticization, making it play a more and more important role. Biodegradable particles are plastic products with improved flame retardancy, strength, impact resistance and toughness.

早期，可降解成分或光敏剂（如淀粉）被添加到传统塑料中，而不会影响其功能。在自然条件下，可生物降解的成分被降解，从而破坏了整个产品结构，这不仅有利于减少塑料袋的“飞扬”，也有利于加速耐火成分的降解。

In the early stage, degradable components or photosensitizers (such as starch) were added to traditional plastics without affecting their function. Under natural conditions, biodegradable components are degraded first, thus damaging the whole product structure, which is not only conducive to reducing the "flying" of plastic bags, but also conducive to accelerating the degradation of refractory components.

日常生活中遇到的可生物降解颗粒材料：淀粉基塑料。淀粉基塑料是我们生活中比较常见的可生物降解颗粒材料，比如一些一次性餐具。如果你有合适的工具，它的主要成分淀粉也可以在厨房里用淀粉制成。

Biodegradable materials encountered in daily life: starch based plastics. Starch based plastic is a common biodegradable granular material in our life, such as some disposable tableware. If you have the right tool, its main component starch can also be made of starch in the kitchen.

聚乳酸（PLA）。聚乳酸是乳酸中的羟基和羧基脱水形成的聚合物。聚乳酸在整个生产过程中无污染，其性能与许多工程塑料相似，与有机物有良好的相容性。

Polylactic acid (PLA). Polylactic acid is a polymer formed by dehydration of hydroxyl and carboxyl groups in lactic acid. Polylactic acid is pollution-free in the whole production process. Its properties are similar to many engineering plastics and have good compatibility with organics.

聚羟基链烷酸酯(PHA)。PHA可以通过控制细菌种类和发酵过程来改变其组成。PHA可硬如工程塑料，也可软如橡胶，成为近年来降解材料研究的热点。

Polyhydroxyalkanoates (PHA). PHA can change its composition by controlling bacterial species and fermentation process. PHA can be as hard as engineering plastics or as soft as rubber, which has become a research hotspot of degradable materials in recent years.
