Abstract
To satisfy the requirement of haptic sensibility in rubber such as in the proposed hybrid skin (H-Skin), the authors have demonstrated a new method for solidifying rubber using electrolytic polymerization together with configured magnetic clusters of magnetic compound fluid (MCF) incorporated into the rubber by the application of a magnetic field. However, the rubber and magnetic fluid (MF) involved in the MCF rubber were water-soluble. In addition, the authors have demonstrated the practicability of using electrolytic polymerization with an emulsifier, polyvinyl alcohol (PVA), in which natural rubber (NR) or chloroprene rubber (CR) and silicone rubber (Q) can be mixed as water-soluble and water-insoluble rubbers, respectively. In this study, to enhance production, the feasibility of solidifying rubber by electrolytic polymerization is verified using varied water-insoluble rubber, varied water-insoluble MF, and varied surfactants to aid emulsion polymerization, except in the case of other kinds of rubber and MF which have been demonstrated until recent by the authors. Based on these diverse constituents, the authors propose a consummate fabrication process for multi-layered MCF rubber, which involves porous stocking-like rubber that can be permeated by any liquid. The investigation of this application is presented in the sequential second report.
Highlights
Sensors require haptic sensibility in rubber under normal or shear motions, including sensibilities to temperature or photoreaction
The authors investigate the viability of: (1) electrolytic polymerization technique for the solidification of diverse rubbers with diverse combinations of various rubbers and magnetic fluid (MF) using various emulsifiers; (2) the fabrication process of the magnetic compound fluid (MCF) rubber sensor with their combinations and the MCF rubber permeated by liquids, which are the novelty of the current work
The present first report offers the key to an understanding of practicability of electrolytic polymerization for the solidification of rubber with various combinations of diverse kinds of rubber, MF and emulsifier
Summary
Sensors require haptic sensibility in rubber under normal or shear motions, including sensibilities to temperature or photoreaction. The resulting material is named magnetic compound fluid (MCF) rubber This novel solidification method differs from the conventional vulcanization technique, where sulfur is used on the field for the normal production of solid rubber [12]. Because the fabrication of the MCF rubber sensor by the combination of Q, NR, CR, PVA, and water-base MF alone has been proposed [14]. The authors investigate the viability of: (1) electrolytic polymerization technique for the solidification of diverse rubbers with diverse combinations of various rubbers and MFs using various emulsifiers; (2) the fabrication process of the MCF rubber sensor with their combinations and the MCF rubber permeated by liquids, which are the novelty of the current work. MCF rubber sensor to fields related to normal or shear forces and temperature, which is presented in the second report [24]
