Analysis of parameters influencing delamination in thermo-mechanically loaded graphene/polymer layered nanocomposites

The aim of this work is to predict analytically and determine the factors, influencing the interface delamination in layered graphene-polymer nanocomposite structures, subjected to external static thermo-mechanical loading. A 2D analytical modeling (stress-function variational method) of interface shear stress in 3-layered nanocomposites, subjected to thermomechanical loading, is used. The criterion for the model interface delamination in the structure is defined and solved. The parametric analysis of the factors, influencing interface delamination, has been performed and investigated for 3 case studies of combine loaded graphene-polymer nanocomposites: graphene/SU-8/PMMA, graphene/SU-8/PET, and graphene/MoS

/PET. The considerable main factors are geometry characteristics of the nanocomposite structure and magnitude and type of external loading. The expected results will serve as a fast prognosis tool in the future experimental and model research on the graphene-polymer nanocomposite behaviour.
