研究了在大气压下使用甲基丙烯酸缩水甘油酯（GMA，甲基丙烯酸-[2，3-环氧-丙酯]）作为原型前体的基于介质阻挡放电（DBD）的等离子体沉积，以评估介质阻挡放电获得具有起始前体的高度结构保留的等离子体聚合物的适用性。使用放电的脉冲激发，高达约90%的GMA的环氧基团可以保留在以3- 5 nm/s的量级的沉积速率获得的等离子体聚合物中。对脉冲等离子体条件下成膜机理的初步研究表明，脉冲过程中产生的完整单体分子与表面自由基的反应起着重要作用。
Dielectric barrier discharge (DBD)-based plasma deposition at atmospheric pressure, using glycidyl methacrylate (GMA, methacrylic acid-[2,3-epoxy-propyl ester]) as a prototype precursor was investigated in order to evaluate the applicability of dielectric barrier discharges to obtain plasma polymers with a high degree of structural retention of the starting precursor. Using pulsed excitation of the discharge, up to about 90% of the epoxy groups of GMA can be retained in plasma polymers obtainableat deposition rates in the order of 3–5nm/s. Preliminary investigations of the mechanism of film formation under pulsed plasma conditions indicate that the reaction of intact monomer molecules withsurface radicals generated during the pulses play a prominent role.
