[Data] Research Institute of Chemical Reaction Mechanisms, Delamination Mechanism of Heterogeneous Material Interfaces 1

We will introduce a case that elucidates the differences in linear thermal expansion coefficients of PET and PEN films with similar main backbone structures and the mechanisms that produce these differences.

Although they are different materials, if they have similar molecular structures, there is potential for the development and expansion of composite products due to their compatibility and similar properties. However, while they are similar, there are also pitfalls. For example, differences in linear thermal expansion coefficients can lead to stress and displacement at their interface, and cases of delamination are not uncommon. This document presents a case study that elucidates the differences in linear thermal expansion coefficients of PET and PEN films, which have similar main chain structures, and the mechanisms that produce these differences.
