Initiator integrated 3D printing, namely i3DP, was developed by incorporating a vinyl-terminated initiator into UV curable resin to make functional structural materials that enable genetic post-printing surface-initiated modification. Taking advantage of printing and ATRP, the feasible i3DP makes printed complex architectures possible for nearly any desired surface modification various applications, example, even pouring water sieve readily achieved.
In this article, we describe a writable particle-free ink for fast fabrication of highly conductive stretchable circuits. The composite mainly consists soluble silver salt and adhesive rubber. Low toxic ketone was employed as the main solvent. Attributed to ultrahigh solubility in short-chain salt-assisted dissolution rubber, can be prepared into transparent solution. As-prepared has good chemical stability directly filled ballpoint pens use write on different substrates form well salt-based...
Aluminum foil is the predominant cathodic current collector in lithium-based batteries due to high electronic conductivity, stable chemical/electrochemical properties, low density, and cost. However, with development of next-generation lithium batteries, Al collectors face new challenges, such as requirement increased chemical stability at voltage, long-cycle-life different electrolyte systems, well improved conductivity adhesion for electrode materials. In this study, we demonstrate a novel...
