Problems solved by technology

However, when ultrasonic technology is used to prepare nano-metal polymer composites, because ultrasonic waves can promote the polymerization of monomers, it will also break the long chain of the polymer, which is not conducive to the formation of long-chain polymers with a higher degree of polymerization. Although metal polymers are also microspheres with a core-shell structure, the particle size of the microspheres is not uniform and cannot be controlled, which affects the application performance of composite materials

Abstract

The invention relates to the field of nano-copper-polymer composite materials and in particular relates to a method for preparing the nano-copper / PAMPS (pathogen associated molecular patterns) composite material by initiating solution polymerization with ultrasound. The method comprises the following specific operation steps: (1) carrying out polymerization reduction with ultrasound; (2) carrying out thermal relaxation; and (3) washing and drying. By utilizing the method, thermal relaxation is generated by adjusting the temperature, the vacuum degree and the time, polymers are polymerized further to obtain a polymer matrix with high degree of polymerization, and with the existence of copper nanoparticles, interaction force between the nano-copper and the polymer matrix is used as ordering driving force of microstructure to induce polymers to orderly arrange so as to synthetize nano-copper / PAMPS composite particles having core-shell structures and uniform and controllable grain sizes.
