摘要:

通过对大气压等离子体液相沉积工艺过程作用机制的研究,围绕如何提高液相沉积效率问题,构建织物表面微观薄膜沉积过程动力学模型。探讨放电功率、超声频率、处理时间、单体流速、氦气流速对薄膜沉积速率及膜层性能的影响,数值模拟涂层表面形态的变化,得出不同工艺参数下织物表面的沉积率变化规律,揭示薄膜沉积过程中聚合粒子的生长、涂层密度和质量的产生规律。这些结果对于预测成膜结构和优化具体等离子体液相沉积的工艺参数,提高沉积率和沉积薄膜的均匀度及对实际生产中如何提高材料的利用率和节约成本等方面具有一定的指导作用。

Abstract:

Through the research of action mechanism of atmospheric pressure plasma liquid deposition process, centering around how to improve the deposition efficiency, a micro-film deposition kinetics model on fabric surface was constructed. Exploring the discharge power, frequency, treatment time, monomer flow rate, He flow rate on the deposition rate and film properties, numerically simulating changes in coating surface morphology, obtaining the deposition rate variation under different process parameters, disclosing the generation law of polymeric particles growth, coating density and mass in film deposition process. These results have directive significance for predicting film structure and optimizing specific plasma liquid deposition process parameters to improve deposition rate and the deposited film uniformity and how to improve material utilization and save cost in the actual production.
