1. Lin, Chen-Yun. Investigation of Microstructure and Mechanical Properties of Polyvinylidene Fluoride/Carbon Nanotubes Composite which is Effected by Electric Field Polarization: A Molecular Dynamics study.

Degree: Master, Mechanical and Electro-Mechanical Engineering, 2017, NSYSU

In this work, the molecular dynamics simulation (MD) simulation was proposed to investigate the microstructure and mechanical properties of pure Polyvinylidene fluoride (PVDF) and PVDF/Carbon Nanotube (CNT) composites(4.49 wt%, 9.34%, 13.23 wt% of CNTs) which are effected by electric field. For proving that the Dreiding force field can well describe the PVDF material, the density and solubility parameters of the pure PVDF system are predicted and compared with the experimental results. According to the results of annealing simulation, the formation of β phase have been increase about 25% during the annealing procedure both in pure PVDF and PVDF/CNTs composite case. The content of β phase in PVDF and PVDF/CNTs composite have been further enhance around 10% under the electric field. According the stress-strain profiles from the tensile simulation, the Youngâs modulus and ultimate tensile strength of pure PVDF can be improved by blending with CNTs and polarized by electric field. But the mechanical properties of PVDF/CNTs composite has reduce when the blending ratio of CNTs over 13.23 wt%. The analysis of local shear strain and porosity indicate that the strength of PVDFs which around CNTs have been enhanced but the structure became brittle when CNTs weight fraction increased and easy to be fractured. Moreover, the generation of pores can be effectively reduced and the ductility was also improved due to the applied electric field. The trans configuration ratio in PVDF and PVDF/CNTs composite have been increase during the tensile process, but such enhancement are reduced in electric field polarization system. By taking advantage of this molecular simulation procedure, The properties of PVDF/CNT composites could be fast predicted, and the simulation results can investigate the material in atomistic-level and also provide new pathway to reduce the cost and research time in experiments.
