Problems solved by technology

However, the use of temperature in this method is only applicable to the pre-preparation process of artificial muscles, but ignores the possible improvement of actuation performance brought about by further processing.
This is true of all current research on CAH artificial muscles. Due to the relatively innovative ideas of the heat treatment process, no relevant research has yet appeared.

Embodiment Construction

[0017] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0018] A heat treatment process flow chart for processing CAH artificial muscles, such as figure 1 As shown, the process is mainly that the artificial muscle goes through four stages of cross-linking, heating, heat preservation and cooling in solid state. These processes are connected with each other and complement each other. The CAH artificial muscle is composed of an electric actuator membrane and two electrode membranes. The two electrode membranes are respectively covered on both sides of the electrical actuator membrane, and are fitted together to form an electric actuator similar to a "sandwich" structure. In order to prevent deformation of the artificial muscle during heat treatment, its initial thickness should be uniform, its shape should be symmetrical, and a margin for heat treatment should be reserved to obtain the expec...

Abstract

The invention provides a heat treatment process method for processing CAH (Calcium Alginate Hydrogel) artificial muscles. The heat treatment process method adopts a vacuum and whole heating manner and comprises four phases of cross-linking, heating, keeping heat and cooling. The heat treatment process method comprises the main method steps: immersing the artificial muscles into a CaCl2 solution and carrying out an ion cross-linking reaction for 20min at a water bath temperature of 30 DEG C; then carrying out stress relieving annealing and putting the artificial muscles into a drying box for heating; setting corresponding parameters; taking out the artificial muscles and cooling with air at an indoor ventilation part; keeping for 30min and putting the artificial muscles into a vacuum drying box for 0.5h; adjusting the set parameters, and slowly cooling to 50 DEG C along a vacuum box and keeping the temperature constant for 1.5h until tempering treatment is finished; finally, standing in air for 3h, and gradually cooling to a room temperature to finish an ageing process; and cutting, packaging and storing. The heat treatment process method provided by the invention has a clear principle and a remarkable effect, and can be commonly applied; and comprehensive mechanical properties including a responding speed, a service life, output power and the like of the CAH artificial muscles can be effectively improved.

Description

technical field [0001] The invention relates to a heat treatment process, in particular to a heat treatment process for processing CAH artificial muscles. Background technique [0002] CAH (calcium alginate hydrogel, calcium alginate hydrogel) is an ionic electroactive polymer, and its actuation performance is very similar to that of biological muscles, so it is called "artificial muscle". CAH materials are soft, elastic, and biodescriptive, and can produce larger displacement deformations at lower driving voltages. Therefore, it has broad application prospects in the fields of bionic engineering, micromechanics and biological sciences. Response speed, lifespan and output force are important indicators to measure CAH artificial muscles. At present, scientists at home and abroad have conducted a lot of research on it, mainly focusing on preparation methods and doping processes to improve the actuation performance of these three aspects. Therefore, it is necessary to explore...
