Abstract

A home-made plasma source with a Langmuir electrical probe was built for this work in order to create a plasma beam that could be utilized successfully in a range of uses. By modifying the operational parameters, including the discharging voltage, cathode-anode spacing, as well as argon (Ar) pressure, a steady discharging media was achieved. Additionally, a locally design electrical probe is introduced into the discharging plasma to monitor the current-voltage (I-V) characteristics curve in order to assign plasma properties. The probe is moved to any intended destination in the plasma volume and has the following dimensions: 1 mm in length, 0.5 mm in diameter. The gas pressure as well as probe-cathode separation are modified to record the plasma characteristics including electron density and electron temperature. As the pressure rises from 0.15 up to 0.3 Torr, it was found that the electron temperature Te varies 4.66*104 to 2.91*104 eV. By subjecting PET polymeric film to Ar plasma beams, its surface wettability is altered. By increasing the plasma period from 0 to 8 minutes, the overall surfaces free energy is raised from 32.2 to 67.7 mJ/m2. Additionally, the developed plasma source is highly efficient and tailored to satisfy the needs of applications like polymeric-surface modifications.

改性氩辉光等离子体源对PET聚合物表面性能的影响

为了这项工作，我们制作了一个带有朗缪尔电探针的自制等离子体源，以产生一种可以在各种用途中成功利用的等离子体束。通过修改操作参数，包括放电电压、阴极-阳极间距以及氩气（Ar）压力，实现了稳定的放电介质。此外，在放电等离子体中引入了局部设计的电探针，以监测电流-电压（I-V）特性曲线，从而分配等离子体特性。探针被移动到等离子体体积中的任何预期目的地，并具有以下尺寸：1 长度为mm，0.5 直径为mm。对气体压力和探针阴极分离进行了修改，以记录等离子体特性，包括电子密度和电子温度。当压力从0.15托升至0.3托时，发现电子温度Te变化为4.66*104至2.91*104 通过使PET聚合物膜经受Ar等离子体束，其表面润湿性发生改变。通过将等离子体周期从0分钟增加到8分钟，整个表面自由能从32.2分钟提高到67.7分钟 mJ/m2。此外，所开发的等离子体源是高效的，并可满足聚合物表面改性等应用的需求。
