Surface Modification of Polyimide Films by an Ethylenediamine Treatment for a Flexible Copper Clad Laminate
E-mail:,
The surfaces of the polyimide films Kapton-E and Upilex-S are modified by ethylenediamine treatment to improve its adhesion to a subsequently deposited copper layer. The changes in the chemical composition, morphology, and adhesion properties of the modified polyimide surface are characterized by X-ray photoelectron spectroscopy, atomic force microscopy, and the 90℃ peel test. An ethylenediamine polyimide treatment induces amino group formation from the broken imide group. The peel strength of Kapton-E and Upilex-S with a copper layer increases from 0.3 to 0.65 kgf/cm and 0.25 to 0.46 kgf/cm, respectively. The results show that ethylenediamine treatment is a good modification method to greatly increase the adhesion performance of polyimide films to a copper layer.
