Self-Oscillating Structural Polymer Gels
Self-oscillating polymer gel has become a distinguished class of smart soft materials. Here we fabricated and demonstrated a self-oscillating structural gel network with the incorporation of the Belousov-Zhabotinsky (BZ) reaction. The structural polymer gel oscillates at a macroscopic level with remarkably faster kinetics compared to a normal gel of similar chemical compositions. The structural...
متن کاملShape- and size-dependent patterns in self-oscillating polymer gels†‡
Polymeric hydrogels that exhibit autonomous, coupled chemical and mechanical oscillations are a unique example of synthetic, active soft matter. Here, we explore the effects of gel aspect ratio and absolute dimensions on pattern formation in hydrogels undergoing the Belousov-Zhabotinsky (BZ) reaction. We synthesize and analyze N-isopropylacrylamide gels containing covalently bound BZ catalyst a...
متن کاملFlow Structures Generated by Pressure-controlled Self-oscillating Reed Valves
The #ow structures generated by a pressure-controlled self-oscillating valve are investigated both experimentally and numerically. Schlieren #ow visualization experiments show that a stable vortex is developed downstream of the valve during the closing phase of the valve. During the opening phase of the valve, this vortex moves downstream and dissipates. An experimental study of the vortex inte...
متن کاملChemomechanics of Self-Oscillating Gels
Biological materials such as cardiac and skin tissue exhibit the unique capacity to transduce mechanical stimuli into propagating electrical and chemical signals throughout the body. Few synthetic materials have been engineered to produce communicative chemical signals in response to mechanical input, though such synthetic material analogues could enable devices that mimic biological tissues an...
متن کاملChemo-responsive, self-oscillating gels that undergo biomimetic communication.
Species ranging from single-cell organisms to social insects can undergo auto-chemotaxis, where the entities move towards a chemo-attractant that they themselves emit. Polymer gels undergoing the self-oscillating Belousov-Zhabotinsky (BZ) reaction exhibit autonomous, periodic pulsations, which produce chemical species collectively referred to as the activator. The diffusion of this activator in...
