The invention discloses a polyethylene-copper nanoparticle composite material as well as a preparation method and application thereof, and relates to the technical field of anti-pollution materials. Comprising a polyethylene matrix and copper nanoparticles dispersed in the polyethylene matrix, and the copper nanoparticles are Tween modified copper nanoparticles. The copper nanoparticles are added into the polyethylene material, so that on one hand, the copper nanoparticles have a relatively good inhibition effect on bacteria, and on the other hand, the growth of aquatic organisms can be inhibited; on the other hand, the copper nanoparticles can improve the mechanical property and thermal stability of the polyethylene material, and the effect of prolonging the service life of the polyethylene material from double angles is achieved. The polysorbate modified copper nanoparticles can be slowly released, the good anti-pollution performance of the polysorbate modified copper nanoparticles can be exerted, meanwhile, the copper nanoparticles can be evenly dispersed, and the overall antibacterial, anti-corrosion and anti-pollution performance of the polyethylene-copper nanoparticle composite material is improved.
本发明公开了一种聚乙烯‑铜纳米颗粒复合材料及其制备方法和应用,涉及抗污染材料技术领域。包括聚乙烯基体和分散于聚乙烯基体内的铜纳米颗粒,铜纳米颗粒为吐温改性的铜纳米颗粒。通过在聚乙烯材料中加入铜纳米颗粒,一方面对细菌有较好的抑制作用,同时可以抑制水生生物的生长;另一方面,铜纳米颗粒能够改善聚乙烯材料的机械性能和热稳定性,达到双重角度提高其使用寿命的效果。采用吐温改性后的铜纳米颗粒能够使得铜纳米颗粒缓慢释放,发挥其良好的抗污染性能,同时能将铜纳米颗粒分散均匀,提高了聚乙烯‑铜纳米颗粒复合材料整体的抗菌、防腐和抗污染性能。
