“…From Figures 3(b), it can be seen that generally ∆G (100 rad/s, 1 kV/mm) increases linearly with temperature, consistent with Equation 1, and attains maximum values of 3.12 × 10 5 , 2.48 × 10 5 , and 1.87 × 10 5 Pa for the NORDEL IP 4570, 4640, and 4520, respectively, at a temperature of 380 K. Kunanuruksapong et al [20] reported that (∆G) and (∆G/ 0 G ) of acrylic elastomers increased with increasing temperature at a frequency of 1 rad/s. ∆G and ∆G/ 0 G of styrene copolymer increased initially and then decreased at temperatures above T g [20], because at temperatures above T g , the materials change from a rubbery -like state to a plastic-like state [20].…”

“…∆G and ∆G/ 0 G of styrene copolymer increased initially and then decreased at temperatures above T g [20], because at temperatures above T g , the materials change from a rubbery -like state to a plastic-like state [20]. Sato et al [21] studied the rheological properties of a styrene copolymer (SIS triblock copolymer) in n-tetradecane as a function of frequency and temperature without an electric field.…”

“…The PMMA/CNFs nanocomposite fibers also show enhanced thermal stability, significantly reduced shrinkage and enhanced modulus retention with temperature, as well as improved compressive strength [50]. The electrical properties and electromechanical responses of acrylic materials such as acrylic elastomers and styrene copolymers can be improved toward electroactive applications such as artificial muscle and/or micro-electromechanical systems (MEMS) devices [51].…”

Acrylic-based polymers have many currently important biomedical applications such as contact lenses, corneal prosthesis, bone cements, tissue engineering, etc. due to their excellent biocompatibility and suitable performance in mechanical properties, among many other applications. Many of these biomaterials have been approved by the US Food and Drug Administration (FDA) for various applications. However, the potential uses of these polymeric materials in the biomedical industry could be increased exponentially if some of their acrylic properties (mechanical strength, electrical and/or thermal properties, water sorption and diffusion, biological interactions, antibacterial activity, porosity, etc.) are enhanced. Thus, acrylics have been fabricated as multicomponent polymeric systems in the form of interpenetrated polymer networks or combined with other advanced materials such as fibers, nanofibers, graphene and its derivatives and/or many other kinds of nanoparticles to form composite or nanocomposite materials, which are expected to exhibit superior properties. Besides, in regenerative medicine, acrylic scaffolds need to be designed with the required extent and morphology of pores by sophisticated techniques. Even though the great advances have been achieved so far, much research has to be carried out still in order to find new strategies to improve the above-mentioned properties.

“…An electric fieldstimulated polymer-based actuators are referred to as electroactive polymers (EAPs) [2,3,7,9,10]. EAPs have the advantages, such as light weight, flexible, tolerance against fracture, and easy to fabricate, and they can convert electrical energy to mechanical energy and thus impart a force and produce large strain [2,3,[6][7][8][9][10][11][12][13].…”

We fabricated an actuator that was made from polyurethane (PU) with carbon nanotubes (CNTs) as the filler. To improve the dispersion of the CNTs, a mild hydrothermal treatment was carried out. Carboxyl and hydroxyl groups were introduced to the surface of the CNTs, and they were found to be highly dispersed in polar solvents such as dimethylformamide. To evaluate these films, we mainly focused on electrical properties, such as dielectric spectroscopy, space charge measurements, and actuator behavior. We found that the PU/CNTs film bents toward the cathode when an electric field was applied, and it reverted to its original position when the electric field was removed. Upon the inclusion of the CNTs as the filler for the polymer, the electrical properties of the films improved significantly. The highly polarized films had a high relative permittivity, and this produced a higher Maxwell pressure, which assisted the actuation. A high accumulated charge density was observed from space charge measurements in some of the films, and this explains the bending direction and the actuation mechanism.
