Magnetic double-network composite capable of large recoverable deformation

Deformation Characteristics of Composite Structures

The composites provide design flexibility because many of them can be moulded into complex shapes. The carbon fibre-reinforced epoxy composites exhibit excellent fatigue tolerance and high specific strength and stiffness which have led to numerous advanced applications ranging from the military and civil aircraft structures to the consumer products. However, the modelling of the beams undergoin...

Statistical Modeling Applied to Deformation-Relaxation Processes in a Composite Biopolymer Network Induced by Magnetic Field

This study investigated a methodology based on image processing and statistics to characterize and model the deformation upon controlled and uniform magnetic field and the relaxation under zero field of droplets observed in aqueous solutions of sodium alginate incorporating magnetic maghemite nanoparticles stabilized by adsorption of citrate ions. The changes of droplet geometry were statistica...

Monolithic fabrication of ionic polymer–metal composite actuators capable of complex deformation

Ionic polymer–metal composites (IPMCs) are soft actuation materials with promising applications in robotics and biomedical devices. However, traditional IPMC actuators can generate the bending motion only. In this paper, a lithography-based approach is presented for monolithic, batch-fabrication of IPMC actuators that are capable of complex deformation. Such an actuator consists of multiple, in...
