“…10−15 The electronic paste must have the ability to easily pass through the network and excellent printability such as good flatness and large aspect ratio. 16,17 Electronic paste is mainly composed of functional phase, binding phase (glass phase), and organic medium. As one of the most important components of electronic pastes, 18,19 organic medium is a polymer solution dissolved in an organic solvent, which mainly wets the functional and binder phase solid powder to make it a paste with fluid properties.…”

Electronic paste features high quality, high efficiency, advanced technology, and wide application range, attracting tremendous attention in the field of information and electronics. However, few studies have been carried out to focus on the organic medium, a key material for electronic paste. Herein, a general method for controlling the wettability and rheological properties of organic medium is presented by introducing a contact angle meter and rheometer. When DGME/TE = 1:1, the contact angle between the solvent and the diverse bases is the smallest, indicating that the solvent has the best wettability. This method provides an idea for choosing the solvent. Meanwhile, by comparing the recovery rates of the three binders with different contents, acrylic resin always shows a better recovery rate. Subsequently, when HCO/PW = 1:1, organic medium exhibits excellent thixotropy. The three-interval thixotropy shear test through the rheometer allows for finding general guidelines for the selection of binders and thixotropic agents. This work provides a valuable guidance for designing organic medium for electronic paste in the future research.

“…Yan et al fabricated a strain sensor via printing conductor and elastomer simultaneously using a coaxial nozzle where two outlets are coplanar [ 26 ]. Coaxial flow printing is a simple way that cannot only print multi-materials at the same time, but also control the inner flow by flow focusing [ 27 , 28 ]. Yuk et al tried to break the limitation of existing Direct Ink Writing (DIW) 3D printing by harnessing deformation, instability and fracture of viscoelastic inks [ 29 ].…”

Recently, high-resolution patterning techniques of stretchable electronics advanced extensively. An important trend is to fabricate complex circuits with varied sizes in a small area, which is a technical challenge to current conductive ink printing technologies. Here, we introduce a new strategy for multi-resolution liquid alloy printing, which can tune the resolution of printed liquid alloy trace in real time with the squeezing effect of compound viscoelastic flow. A newly developed coaxial nozzle with the inner nozzle extension (CNINE) is used to wrap and squeeze liquid alloy steadily and effectively. By controlling the working parameters and compound flow properties, liquid alloy patterns with different widths are obtained continuously. This work offers a new way to rapidly manufacture complex stretchable electronics patterning in multi-resolution.
