| Summary: | 碩士 === 國立屏東科技大學 === 材料工程所 === 100 === The Pt electrodes are widely found in the ionic polymer-metal composite (IPMC) actuators in the academic and industry field. This option results in an increase in the cost of unit area of commercial IPMC actuator. Besides, two steps of oxidation-reduction reaction process in the plating of Pt powder on the surfaces of PEM film means that preparation time for the IPMC actuator will be belonged. The development of a novel manufacture process with Ag electrodes to reduce the cost and time for preparation of IMPC actuator while maintains the necessary electro-mechanical mechanism with stimulation is the aim of present work.
The base structure of present fabricated IPMC actuator is the Nafion-117 film. After finished the fabrication process of IMPC actuator with sandblast coarsening method in the open literature, the surface topology observation and displacement measurement on both sides of bending levels revealed that some defects existed o the products. This is due to the non-uniform distributions of Pt electrode layers on both sides of IPMC strip. A novel pre-treatment process with the low power laser beam to coarse the outer surfaces of PEM film before electroless plating a thin layer of Pt or Ag layer was developed and tested. A reasonable modification in the planarization in shape and balance in the displacement of IMPC strip on both sides was obtained. A simple manufacture process with one step of oxidation-reduction process for plating of Ag layer as the electrodes was also evaluated. The electro-mechanical properties of present IMPC actuator with Ag electrodes was tested with self-assembled equipments.
In order to evaluated the optimal combinations of parameters on the fabrication of Ag-based IPMC actuator, the design of experiments method as Taguchi orthogonal array was conducted. After finished the ANOVA analysis, the optimal combination for maximum displacement of IPMC actuator is A2 (power of laser beam of 4W)、B1(ammoniacal silver concentration of 0.025M)、C2(glucose concentration of 0.05M)、D1(reduction temperature of 20oC.
