Introduction

Under the strategy of saving resources, protecting the environment and sustainable development proposed in the national 13th five year plan, Geopolymer Materials, as non sintering ceramic materials, which mostly prepared from industrial waste, has attracted people's attention. Due to its special three-dimensional  network structure of inorganic polycondensation, it has the advantages of low reaction temperature, corrosion resistance, low energy consumption and low carbon dioxide emission. It has broad application prospects in the fields of building ceramics, refractories, aquarium filters, silencing baffles and so on. However, its mechanical properties are slightly lower than those of high-temperature sintered ceramics, and there is still room for further improvement. This project proposes to use high-strength ceramic nanofibers as reinforcements, study the impact of nanofiber surface treatment and coating technology on the interface, explore the strengthening and toughening mechanism of geopolymer, and break through the bottleneck of mechanical properties of Geopolymer Composites, which will provide a solid foundation for expanding its application market.

Progress

Optimize the process and find suitable application scenarios at the same time

In terms of geopolymers, after a period of exploration of different ratios and processes, we have mastered the preparation processes of different geopolymers, and the experimental results show that the fibers and processes we choose have significantly improved the high-temperature performance of intestinal anastomosis.

In terms of ceramic 3D printing, we have successfully printed some works of art with difficult shape, some industrial workpieces that may be suitable for ceramic 3D printing process, and also made materials suitable for printing of other types of ceramics (such as zirconia and Geopolymer). At present, we are further optimizing the printing equipment, process and raw materials, and are looking for suitable application scenarios for this technology.
