Problems solved by technology

Generally speaking, antibacterial agents can be divided into two types: one is inorganic antibacterial agents, which slowly release antibacterial ions through the carrier to achieve the purpose of antibacterial. Such carriers and metal ions have low toxicity, good durability and safety, but some Some metal ions, such as silver ions, are easy to generate oxides or be reduced to simple metals after photocatalysis, so they are often accompanied by discoloration; the second is organic or natural organic antibacterial agents, which have quick-acting and excellent anti-mold effects, etc. characteristics, but at the same time, it has the disadvantages of high toxicity, poor heat resistance, short duration of drug effect, etc.
In addition, due to the characteristics of the surface energy of ordinary nanometer-sized antibacterial agents, it is easy to agglomerate in polymer materials, and cannot effectively achieve the technical effect of antibacterial
