Electrical Actuation And Vision-Based Control Of Shape Memory Polymer Carbon Nanocomposites

Abstract

Shape memory polymers (SMPs) are one of the most popular smart materials due to their fantastic properties and greatly potential application in recent years. This paper presents a study on the synergistic effect of carbon nanofiber (CNF) and carbon nanofiber paper (CNFP) on shape memory polymer (SMP) nanocomposites actuation by applying electric current. Shape memory effect has been greatly improved due to the significant increase of electrical conductivity by combining CNF and CNFP into SMP composites. CNFP is used to facilitate the actuation by electrical resistance heating. In order to accelerate the electro-active response, the bulk thermal and electrical conductivity of SMP nanocomposite is increased by mixing CNFs with SMP. A vision based 3D coordinate prediction system is designed to sense and controls the deformation of the SMP composites with current and voltage applied. Compared with baseline material, the recovery speed of SMP nanocomposites is increased up to 1,000%. In order to investigate the themomechanical property of SMP composite, Dynamic Mechanical Analysis (DMA) test has been carried out as well. Furthermore, the control tests of SMP nanocomposites show that they had a reasonably fast response of ∼90 seconds. In the conducted 100 experiments and the desired deflection angle can be achieved within a 5% error bound.
