Plastics are the guarantee of our high quality of life.

In most people's perceptions, plastic is an inexpensive material. When it comes to plastics, the first thing that comes to mind is plastic bags. Then people naturally extend to "white pollution," and then they associate some simple plastics. Products, such as plastic bottles, plastic buckets, plastic toys, etc. But we have to admit that plastic has been greatly wronged. In fact, we generally have misunderstandings about it. In most people's minds, plastic recycling is okay once or twice, but as the number of recycling increases, the quality of plastics will also decrease. So how many times is the number of plastic recycling times? Scientists say that plastics can be recycled indefinitely.

Nowadays, plastic waste is sweeping over, and the reason may be related to the recycling of plastics. In general, we generally believe that the number of plastics recycled is limited, and can be recycled up to three or four times. The reason for the limited number of plastics to recycle is because the properties of the plastic will decrease with each melt remodeling. For example, it loses plastic fluidity, becomes brittle, becomes turbid, opaque, and even discolored (eg, yellowing). Once the mechanical or optical properties of the plastic change, it is no longer suitable for the initial purpose of use. However, a high molecular polymer allows plastics to have good plasticity and achieve unlimited recycling.

It is reported that the newly developed infinitely circulating plastic has a cross-linked chemical domain that gives it a rigid character that can be hydrolyzed only at very low pH (eg, pH = 0). By calculating the chemical conditions and simulating the curing conditions and monomers required for the best performance materials, the scientists analyzed the best synthetic methods to make the thermoset plastics soft and flexible. In addition to the commonly used uses, plastic can do a lot of unexpected things because it can change its properties by adding other chemical components. Conductive plastics (such as OLED), antibacterial plastics (such as disposable medical devices), or lightweight high-strength plastics (such as Boeing 787 tail composites) have brought many surprises to our human life. Plastics not only save fuel, reduce carbon dioxide emissions, but also help prevent disease.

It is understood that plastic materials that can be recycled indefinitely can be applied to paints and coatings, and this final confirmation begins with an unexpected discovery. The reason why plastic materials can be used for self-healing coatings is because scientists have combined their self-healing chemical motifs with the coating's hybrid structure, which ultimately allows the paint to adapt to its environment and is resistant to cracking and scratching. Traces and other properties. All of these indicate that plastic is the guarantee for the high quality of our human life. We must change our previous perception of plastics and let plastics create higher interests for us.
