| 目的 研究分析等离子辅助原子层沉积技术(ALD)技术在PET表面上沉积超薄Al2O3阻隔层的工艺优化。方法 采用单因素结合响应面设计试验法，对Al2O3/PET薄膜的沉积速率(GPC)进行优化，通过AFM分析得到薄膜的生长模式和表面粗糙度，最后用水蒸气透过率表征薄膜的阻隔性能。结果 最大GPC的沉积参数:TMA脉冲时间为0.17 s、吹扫时间为11 s、O2的脉冲时间为0.35 s、吹扫时间为10 s、沉积速率为0.215 nm/cycle;薄膜以层状生长模式生长，表面粗糙度均方根(RMS)为0.58 nm;沉积500个循环后薄膜的水透过率从7.456 g∙d/m2降低到0.319 g∙d/m2。结论 通过响应面法优化了ALD制备工艺参数，Al2O3在PET表面沉积100 nm左右时，水蒸气阻隔性提高了25倍。 |

| The work aims tostudy and analyze the process optimization of deposition of ultra-thin Al2O3 barrier layer on PET surface by plasma-assisted atomic layer deposition (ALD). The deposition rate (GPC) of Al2O3/PET film was optimized by single factor combined with response surface design method. The growth mode and surface roughness of the film were obtained by AFM analysis. Finally, the barrier property of the film was characterized by water vapor transmission rate. According to the experimental results, the deposition parameters of the largest GPC were:TMA pulse time 0.17 s, purge time 11 s, O2 pulse time 0.35 s, purge time 10 s, deposition rate 0.215 nm/cycle; the film grew in a layered growth mode with a rough surface. The root mean square (RMS) was 0.58 nm; the water permeability decreased from 7.456 g∙d/m2 of the original film to 0.319 g∙d/m2 after 500 cycles of deposition. The preparation parameters of ALD are optimized by response surface methodology, and the water vapor barrier was increased by 25 times when Al2O3 is deposited on PET surface at about 100 nm. |
