Disclosed are a preparation method for a graphene aerogel array sensor and use thereof. A miniature graphene aerogel array device is prepared by combining in-situ printing and solvent plasticization and foaming, which has excellent flexibility and stability, and is suitable for use in a variety of scenarios, such as sensors, and energy storage devices, etc. The array sensor provided in the present disclosure exhibites extremely high stability, high accuracy and reliability. Combining with deep machine learning, the array sensor can be endowed with the function of learning and recognition of machine intelligence, thus greatly promoting the development of the next generation of artificial intelligence.

Miniature graphene aerogel device and preparation method thereof

In the present invention, a multi-stage foam sound-absorbing black body material is provided for the first time. A graphene aerogel is introduced into a commercialized polymer foam skeleton by using a solvent plasticizing and foaming technology, so as to embed ultra-thin graphene drums in the foam skeleton. When sound waves enter the foam black body, a large number of graphene drums generate a severe resonance effect, thereby rapidly achieving attenuation of the sound waves, and combined with the friction loss of the porous structure of the polymer foam on the sound waves, excellent sound-absorbing performance is achieved in a wide frequency range. The present solution is provided on the basis of commercialized foam materials, has a simple method, low costs, and the potential of wide industrial application.

Multi-stage foam sound-absorbing black body material and preparation method thereof

The present invention provides a method for preparing an aerogel based on plasticizing and foaming with solvent, and the aerogel material is prepared through plasticization with solvent and generation of in-situ bubbles. The method solves the difficult problem that the non-polymer is difficult to realize thermoplastic foaming, and has wide applicability. In addition, a lot of foaming agents can be uses for this method, and this method is easy to implement, and does not require a special drying process, so that the industrialization development of the porous aerogel is greatly promote.
