以二氧化硫(SO2)为工艺气体，对无机粘土(膨润土)进行低温等离子体处理，将含硫和含氧的官能团(磺酸基团)接枝到惰性粘土表面。通过测量硫含量随等离子体功率、气体流量和处理时间的变化，优化了SO2等离子体改性的条件。结果表明，硫含量随着等离子体功率的增大和处理时间的延长而增加。为了控制等离子体物相并表征不同放电条件下SO2等离子体中原子物种的不同激发过程，提出了一种光学发射光谱。通过X射线衍射谱、X射线光电子能谱、傅立叶变换红外光谱和热分析等测试手段对接枝后的膨润土粉进行了表征。
Low temperature plasma treatment of the inorganic clay (Laponite) using sulfur dioxide (SO2) as a process gas was carried out in order to graft the functional groups containing sulfur and oxygen (sulfonic acid groups) onto the inert clay surface. Conditions for SO2 plasma modification were optimized by the measurement of the sulfur content as a function of the plasma power, gas flow rate and treatment time. It was found that the sulfur content increased with the increasing of the plasma power as well as the treatment time. Optical emission spectroscopy was presented in order to control the plasma phase and to characterize the different excitation processes of atomic species in SO2 plasma under different discharge conditions. X-ray diffraction spectrometry, X-ray photoelectron spectroscopy, FTIR and thermal analysis measurements of grafted Laponite powder completed the characterization.
