Description

technical field [0001] The invention relates to a basement film roughening device and method, in particular to a microneedle-based automatic basement film roughening device and method. Background technique [0002] IPMC, English full name: ion-exchange polymer metal composite (ion-exchange polymer metal material), is an artificial muscle material, a new type of flexible intelligent material emerging in the 20th century, under the action of low voltage (1-10V) , will produce a large bending deformation, which belongs to a typical ionic electroactuated polymer. Its light weight, good flexibility, large deformation, and fast response are of great significance in the research fields of biomedicine, optical devices, flexible bionic machinery, micro-electromechanical systems, and aerospace. [0003] IPMC is composed of a polymer base film and upper and lower electrodes. The traditional IPMC preparation process mainly includes four steps: surface roughening of the base film, immer...

AI Technical Summary

Problems solved by technology

Wang, Jin Ning, Chang and others have done relevant research on parameters such as sandblasting time and sandblasting pressure, but generally speaking, there is still a lack of comprehensive understanding of the current sandblasting process parameters, and there is no unified reference range, and the spraying The instantaneous pressure during the sand grinding process can easily cause sand particles to be injected into the base film and be difficult to remove, which will have a great impact on the material properties

Kim, Choi, Saher, etc. conducted in-depth research on nano-level plasma etching technology. This technology has high repeatability, but it requires high equipment and environmental requirements and costs. The etching mechanism is complicated and the processing area is limited, which is not conducive to Industrial production

Noh, He Qingsong, etc. formed a multi-level texture structure of strip-shaped micro-nano grooves on the surface of the polymer base film by combining the etching mold (such as: Al foil, etc.) with the hot-pressing process, increasing the surface electrode thickness and electrode interface area to achieve the purpose of roughening the base film, but the research shows that this process requires high mold precision, complicated operation, corresponding pressure equipment is required, the cost is high, and the prepared material electrode is easy to fall off

[0006] At present, the roughening process of IPMC material base film has not yet formed a unified standard, which makes the stability of the existing process poor. Therefore, a low-cost, automatic base film roughening device is proposed to improve and standardize the roughening process and improve the process of The controllability, consistency and stability of IPMC materials have positive significance for the preparation, production and application of IPMC materials!
