摘　　要：以不锈钢筛网为模板,通过热压印技术制备线型低密度聚乙烯(LLDPE)疏水膜,研究了热压印温度和压力对LLDPE疏水膜结构和性能的影响。结果表明:利用热压印技术能在LLDPE膜表面构筑结构完善的微米级棱状结构,赋予LLDPE膜良好的疏水性能;综合考虑热压印温度和压力的影响,确定LLDPE疏水膜的最佳热压印温度和压力分别为115℃和4.68 MPa,此时膜表面的水接触角达142.5°,滚动角为7.0°,LLDPE疏水膜在实际应用中表现出优异的疏水性能。Using the stainless steel meshes as the template,the linear low density polyethylene(LLDPE)hydrophobic film was prepared by hot embossing technology.The influence of hot embossing temperature and pressure on the structure and hydrophobicity performance of LLDPE hydrophobic film was explored.The results show that the well-defined micron-scale columnar structure can be constructed on the surface of LLDPE film by hot embossing technology,which gives it excellent hydrophobic performance.Considering the influence of hot embossing temperature and pressure,the optimal processing parameters of LLDPE hydrophobic film is fixed at 115℃and 4.68 MPa.The water contact angle of LLDPE hydrophobic film is up to 142.5°,and the rolling angle is 7.0°.LLDPE hydrophobic film showes excellent hydrophobic performance in practical application.
