Abstract Scope |
In most printed electronics applications, resistive inks and dielectric inks print resistors and insulators separately. However, handling two different inks is always challenging and may cause various issues. As a solution for this, we have developed a convertible ink by blending a silver (Ag) nanoparticle ink with a barium strontium titanate (BST) nanoparticle ink. The Ag-BST convertible ink shows the insulating phase after curing for 20 minutes at 80 ⁰C. During the selective laser sintering process, conductive nanoparticles will melt and reflow to form conductive paths. The laser sintering changes the 3D physical morphology of the Ag-BST film without changing the intrinsic properties of either Ag or BST nanoparticles. The conductivity of the laser-sintered areas depends on the wavelength of the laser, the laser power, the laser rastering speed, and the laser penetration depth. This innovative new material can be used in a wide range of printed electronics applications. |
