Generally, the primer used on the material surface to increase the adhesion of adhesive before using adhesive, and then we apply adhesive to make the midsole and outsole bonding effectively. The primer is mostly solvent-based, excellent for the polymer material Surface cleaning, corrosion, increased wetting and other functions, but will cause harm to the environment and human. 　　We used the cold atmospheric pressure plasma to modify the surface of midsole(EVA) and outsole(NBR). The plasma is clean and will not cause damage to the environment and human, which is more convenient at atmospheric pressure. The use of plasma can clean the surface and increase the surface functional groups, so it can be effectively bonded with the adhesive to reach the effect of not using the primer. This study was carried out by different N2 flow rates, different times and different height conditions to research its effect on the peel strength. The surface energy analysis, SEM surface type analysis, EDS surface element analysis, ATR surface functional analysis and T-peel test were carried out. From the results of the study, it was found that the residual area (a) of the original sample was 8% and the peel strength was 1.079 kgf / cm. After the atmospheric plasma was modified, the residual area (a) increased to 99% and the peel strength also increased to 2.222 kgf / cm.
