Abstract

The invention provides a preparation method of a sodium alginate-carboxymethyl cellulose gel actuating membrane. The preparation method comprises the following steps: step 1, preparing a sodium alginate solution; step 2, preparing a sodium alginate-carboxymethyl cellulose solution; step 3, carrying out defoaming pretreatment on the sodium alginate-carboxymethyl cellulose solution; step 4, carrying out freeze drying treatment; and step 5, cutting and storing: cutting the obtained sodium alginate-carboxymethyl cellulose gel actuating film into 40 * 40 mm sample pieces, sealing the sample pieces by using a preservative film, and storing the sample pieces in a constant-temperature box. The preparation process is simple, the film forming rate is high, large-scale preparation can be achieved, a traditional sodium alginate type driving film can be replaced, and application value is achieved in the aspect of practical application of biological gel type artificial muscles.

Description

technical field [0001] The invention relates to a preparation method of a bionic artificial muscle actuation membrane, in particular to a preparation method of a sodium alginate-carboxymethyl cellulose gel actuation membrane. Background technique [0002] With the continuous development of robot technology and the birth of intelligent materials, artificial muscles, as the key part of the drive system, have become the focus of research in the field of bionic robots in recent years. How to make the driving method of electro-mechanical devices simpler, have higher energy conversion efficiency, and improve working life are the main problems for bionic robots to move from the laboratory to engineering practice. Among them, bionic artificial muscles are a research field integrating new driving methods, intelligent materials, and bionics. By applying electric fields, magnetic fields, light, thermal fields and other driving methods to artificial muscles, they can produce movements a...
