Analysis of airgel detectors printing market
In the aerospace industry is the most widely used 3D printing engine parts, but recently, NASA Goddard Space Flight Center researchers say graphene Aerogels injection technology could be used to create 3D printed probe components. In addition, this technique can also be used in manufacturing spacecraft antenna and other hardware. It means all of the electronic components on the circuit board, if the 3D printing can be done directly, it will be a lot of convenience than the traditional process. Goddard Space Flight Center currently being studied whether graphene airgel jet technique has the potential for producing the detector assembly. The 3D printed often assembled using traditional manufacturing process is completed, and shorter manufacturing time, be able to complete a minimum of only 1-2 days, more importantly, they can be manufactured in any shape. As the instrument on the spacecraft very sophisticated, many of which are in units of micrometers in width, it can be used if the airgel injection technology, sophisticated manufacturing methods will redefine the circuit board assembly, and to further improve their performance and stability. A conventional method of manufacturing a graphene airgel is extruded using an inkjet printer with a polymer or mixture of graphene silica at a temperature above room temperature or, which is then removed by heating or chemical methods. However, this method of manufacturing a stacked type has obvious disadvantages, for example it is possible to disrupt the structure of graphene suspension difficult to manufacture complex structure, the finished airgel and poor physical properties, and the K-State this new technique this problem is solved by the \”freeze casting\” combined with 3D printing. It bears Antarctic understood that this method actually graphene oxide suspension was mixed with water, and then in an environment of -25 ℃ to print to a 3D surface. Its advantage is that water freezes, the finished print layer fixed, while supportive, so that the next layer of printing to continue smoothly. This method also has the advantage that the integrity of the airgel structure can be improved, because when the graphene oxide structure deposited onto the frozen, thawed not frozen portion of the surface would have frozen, so that the layers between freedom and re-mixed ice – which will form hydrogen bonds, and it can have an impact on the structure of the airgel. In addition, this method can create graphene airgel having a complicated structure. This is also because the water freezes, forming a support, in order to achieve the graphene oxide suspensionLaminate material. Finally, just remove the water, you get the first goal – graphene airgel. Currently, the project team have been manufactured in this way the density (0.5 to 10) mg / cubic centimeter of airgel. It is not only high quality, but also showed a good electrical conductivity and high compressibility. Future, researchers will further develop this approach, hoping to use a multi-nozzle print and multi-material can be realized.
