Problems solved by technology

If the electrode is only deposited by ion exchange-reduction in the traditional preparation method, the quality of the coating prepared in this way is poor and the resistivity is high, so it is not suitable for direct use.
Further use of electroless plating to improve the electrode is not only time-consuming, but also requires a variety of auxiliary reagents, and has certain requirements for the reaction temperature
These shortcomings limit the promotion and use of IPMC materials to a certain extent

Embodiment 1

[0022] Embodiment 1 The making of wide isolation line multi-electrode IPMC driver

[0023] Taking the size of 15cm×0.5cm and designing two 3mm-wide isolation lines to divide the material into two sections of multi-electrode IPMC drivers along the length direction as an example, the preparation method based on selective plating includes the following steps:

[0024] 1) Pretreatment of materials

[0025] Use Nafion membrane (or Flemion ion membrane) as the base material of the material, use sandpaper to roughen (sandpaper above 600, lightly polish both surfaces of Nafion membrane), try to make the surface evenly stressed when polishing, pay attention to observe the roughness uniformity , Observing the surface under the light becomes cloudy without obvious bright spots, it can be considered that the polishing has achieved a uniform effect. After the roughened Nafion membrane is heated to 60°C, it is ultrasonically cleaned for 20 minutes to remove its surface particles; then it i...

Embodiment 2

[0032] Embodiment 2 The manufacture of thin isolation line multi-electrode IPMC material driver

[0033] Taking a multi-electrode Ag electrode IPMC driver with a size of 6cm×0.5cm and a barrier line width of 0.5mm as an example, the preparation method based on selective plating includes the following steps:

[0034] 1) The pretreatment process of the material is the same as that of Example 1;

[0035]2) Put the material in 200ml of AgNO with a concentration of 0.03mo / L 3 Soak in the solution for 1 hour, cover the pre-plating area with acid and alkali resistant electroplating tape, expose the non-plating area, and then place it in 0.1mol / L HCl solution for half an hour, and the non-plating area will form a non-conductive width of about 0.5mm AgCl isolated wire ( figure 2 ), peel off the electroplating tape evenly and forcefully, and then soak in deionization for about 10 minutes, and then proceed to the next step of soaking reduction plating.

[0036] 3) Place it again in 0...

Embodiment 3

[0041] The making of embodiment 3 composite plating IPMC driver

[0042] Take the palladium and platinum composite electrode type IPMC that is 6cm * 3cm as an example in making the size, the method for composite plating comprises the following steps:

[0043] 1) The pretreatment steps of the material are the same as in Example 1. When making the composite electrode, the activity of the metal needs to be considered, so as to determine the order of plating. First, choose to coat the Nafion film with a metal layer with weak reducibility. Here, choose Platinum-plated electrodes are applied first.

[0044] 2) Place the pretreated material in 0.01mol / L [Pt(NH 3 ) 4 ]Cl 2 Soak in salt for 1-2 hours, soak in deionized water for about 10 minutes, and then place it in NaBH with a concentration of 1mmol / L 4 Soak and reduce in the solution at room temperature, you can see bubbles on the wall of the reaction vessel, when no obvious bubbles appear, it can be considered that the reaction...

Abstract

The invention discloses a selective plating process for an IPMC (Ionic Polymer Metal Composite) drive. The selective plating process is characterized by comprising the following steps: firstly, pretreating a substrate material; secondly, producing a non-plating region on the pretreated ion exchange membrane pretreated in the first step according to the use requirement of the drive to be isolated from a plating region; enabling an electrode not to be plated in the non-plating region in the subsequent work procedure by a mask method; when the line width is greater, directly covering by using a high-temperature-resistant electroplating adhesive tape to enable the blocked part not to be plated, and when the line width is smaller, producing a reverse covering layer by using the electroplating adhesive tape to expose a blocking line and isolating different electrode regions by generating silver chloride precipitation; and thirdly, depositing an electrode layer on the plating region by adopting soaking and reduction plating and producing a platinum, palladium, silver or copper metal electrode or a platinum-palladium composite electrode and a silver-copper composite electrode.

Description

technical field [0001] The invention relates to a selective plating method for an IPMC (ion polymer-metal composite material) driver, using electroplating tape or silver chloride generated by immersion as a mask for the non-plating area. The plating method is simple and efficient, and can Actuators are manufactured with complex shapes to satisfy complex actuation functions. Background technique [0002] Ionic polymer-metal composites (IPMC) have light weight, good flexibility, rapid response, and bidirectional reversible functions of sensing and actuation, and can be used to make electromechanical transducers such as drivers that generate large deformations to replace traditional piezoelectric Ceramics are new intelligent materials that have emerged in the past two decades and have great application potential. [0003] At present, when making segmented, multi-directional, combined deformation and other multi-functional IPMC material drivers, usually according to the needs o...
