Appropriate amount of polyethyleneimine （PEI） dispersants allow the preparation of TiO2 inks with a high solid content of 42 vol.%, which enables them to flow through the nozzles easily.

文摘Three groups of three-dimensional （3D） TiO2 woodpile electromagnetic gap materials with tailed rheological properties were developed for direct-written fabrication.
