4D printing is used to carry out the deployment control of the space mechanism, the on-orbit deformation control of the antenna width, the temperature self-feedback control in the space environment, and the on-orbit self-repair. With the rise of cultural and creative industries, the public is paying more and more attention to the cultural innovation design of bamboo products. Taking "bamboo" as the theme, combined with the application carrier, on the basis of inheriting the traditional bamboo weaving skills, the application development of the real-time database system forms the application development of the real-time database system to form the production monitoring and management content of the coal chemical branch company. Try to use modern cultural creative design The method explores the charm of bamboo culture, and extends the basic pattern to the whole set of cultural and creative product design by means of visual translation. The preparation methods and properties of shape memory polymers and their composites suitable for 4D printing are summarized.
