采用与聚乙烯（PE）相容性好的聚乙烯蜡（PEW）和具备抗静电能力的丙烯酸钠（AAS）通过溶液接枝方法制备抗静电效果显著、效果持久的抗静电剂（PEW-g-AAS）。将抗静电剂与线性低密度聚乙烯/低密度聚乙烯（LLDPE/LDPE）共混后流延制备抗静电聚乙烯（PE）薄膜，研究PEW-g-AAS对PE薄膜性能的影响。结果表明：随着PEW-g-AAS质量分数的增加，PE薄膜的水接触角降低，表面能增加，力学性能稍有下降；当PEW-g-AAS质量分数为20%时，PE薄膜表面电阻下降至5.20×10⁹ Ω，PE薄膜在1~30 d内表面电阻稳定。

Polyethylene wax (PEW) compatible with polyethylene (PE), and sodium acrylate (AAS) with antistatic ability were used to prepare an antistatic agent (PEW-g-AAS) with significant antistatic effect and long-lasting effect by solution grafting method. Antistatic polyethylene films were prepared by casting by blending antistatic agents with linear low-density polyethylene/low-density polyethylene (LLDPE/LDPE), and the effects of PEW-g-AAS on the properties of PE films were studied. The results show that with the increase of PEW-g-AAS mass fraction, the water contact angle of the PE film decreases, the surface energy increases, and the mechanical properties decrease slightly. When the PEW-g-AAS mass fraction is 20%, the surface resistance of the PE film decreases to 5.20×10⁹ Ω, and the surface resistance of the PE film is stable within 1~30 days.
