Analysis of the Applicability of Electroactive Polymers in the Construction of Dispensing Valves

Abstract

Technology of electroactive polymers which react by changing their geometric form under the influence of electrical voltage, has been developed for several decades. The main objective of the research carried out so far, was to develop a technology enabling the usage of such materials as an microscale valves activators. The developed solutions were dedicated mainly to the medical industry, in order to create very small applications, i.e. precisely dosing drugs. This article concerns the analysis carried out in the field of existing electroactive polymers. The conducted research focuses on the verification of their properties, in the context of the possibility to transfer and apply to the valves used in the household appliances. The detailed analysis will be conducted for confirmation, that current technology of electroactive polymers combined with a dedicated mechanical system of the prototype valve, will create favorable conditions for constructing a solution comparable with products present on the market. It will be crucial to confirm that the combination of material and mechanical aspects will ensure stable parameters of linear displacement, force, repeatability in the activation-deactivation cycle and number of cycles possible to reach. Chosen activator material must be examined to ensure smooth movement between the state of activation and precise return to the base shape. In addition, the analysis should indicate what is the environmental influence to the application, and how it will affect on the achievable parameters. The results of the research will allow to find an economically justified alternative to the currently used technology.
