Abstract
A device for processing microstructure arrays of polystyrene-graphene nanocomposites, including a laser generator, a vacuum chamber, an object stage, an ultraviolet filter and a gas flow control unit. The object stage is detachably fixed to a bottom of the vacuum chamber with a passage that can be opened or closed. The ultraviolet filter is provided in the vacuum chamber. A laser light emitted by the laser generator arrives at the object stage through the ultraviolet filter. The object stage is configured to place a sample to be processed. The gas flow control unit is communicated with the vacuum chamber and is configured to control the flow of the gas entering the vacuum chamber. The vacuum chamber is fixed on a three-axis precision positioning platform via a vacuum chamber clamp. The device disclosed herein aims to solve the existing difficulty in processing microstructure arrays of polystyrene-graphene nanocomposites.
