“…In recent years, there has been a flourishing interest in utilizing direct ink writing (DIW) to manufacture ceramics. As the name implies, ceramic DIW technology mixes the ceramic powder with the binder, dispersant, and other additives into a shear-thinning ink material (regardless of droplets or paste) extruded through a certain diameter printing nozzle [128]. Therefore, it is generally regarded as a kind of extrusion-free-forming (EFF) technology [129].…”

Three-dimensional (3D) printing technology is becoming a promising method for fabricating highly complex ceramics owing to the arbitrary design and the infinite combination of materials. Insufficient density is one of the main problems with 3D printed ceramics, but concentrated descriptions of making dense ceramics are scarce. This review specifically introduces the principles of the four 3D printing technologies and focuses on the parameters of each technology that affect the densification of 3D printed ceramics, such as the performance of raw materials and the interaction between energy and materials. The technical challenges and suggestions about how to achieve higher ceramic density are presented subsequently. The goal of the presented work is to comprehend the roles of critical parameters in the subsequent 3D printing process to prepare dense ceramics that can meet the practical applications.

Recently, the wearable electronic devices have attracted extensive attention while the low stretchability and freezing-induced performance deterioration largely limit the applications in many fields. In this work, the poly(acrylamide-co-maleic acid) hydrogels are immersed in the triethylene glycol/sodium chloride/water solution to establish the dual-crosslinked organohydrogels, which present the extraordinary stretchability (1322 ± 75%) ascribed to the energy dissipation of physical interactions and stability of chemical crosslinked networks. Triethylene glycol forms strong hydrogen bonds with water, which interfere with the formation of intermolecular hydrogen bonds among water molecules at low temperatures and inhibit the formation of ice crystals in the organohydrogel networks.Sodium chloride imparts excellent electrical conductivity to the organohydrogel. As a result, a stretchable electronic sensor based on the organohydrogel is fabricated, which is strain-sensitive with a wide strain sensing window (0%-440%) and excellent stability. More importantly, the sensor based on the as-prepared organohydrogel could precisely detect various activities of the human model at À30 C leading to the widely application prospects.

“…However, the crosslinking of photo-polymer led to a rigid and brittle structure. [5][6][7] Crosslinking the molecular chains between layers was one of the effective ways to improve the nal properties of AM materials. 8 While recycling approaches was urgently required for AM materials in view of increasing processing wastes during printing.…”

“…When the distance between two coumarin groups was less than 4.2 m and they were arranged in parallel, the photo-degradation could be carried out. [20][21][22][23][24] Dynamic covalent networks of intrinsic bond exchange reactions such as disulde crosslinks 7 and Diels-Alder (DA) systems also applied. 25,26 However, recyclable so-matter did not meet the actual requirements, especially mechanical properties.…”
