3D Printable Silicone Rubber for Long-Lasting and Weather-Resistant Wearable Devices

Flexible wearable devices based on gels are attracting widespread attentions. However, the stability and fatigue resistance of gels always conflict with their stretchability and conductivity, which severely limit their practical applications. Herein, we propose a flexible gel wearable device based on two networks of thiol–ene and acrylate, exhibiting marvelous flexibility, sensitivity, weather resistance, as well as stability. We use silicone rubber as a cross-linking monomer, and the addition of PC solution containing lithium trifluoride domains the conductivity of the cross-linked polymer. The unique – Si–O– chain of silicone rubber plays a key role in the excellent stability and weather resistance of the silicone rubber, who still maintains good conductivity after exposing outdoors for one month. In addition, our rubber works well within a very large temperature range (−50 °C - 120 °C), which greatly extends the potential applications of gel-based wearable devices. Most significantly, our silicone rubber is 3D printable, which drastically shorten the fabrication time for high-precision complex 3D structures to further enhance the sensitivity of wearable devices. The present study provides the feasibility of making durable and weather-resistant wearable devices working in harsh environment

Mechanochromic Wide-Spectrum Luminescence Based on a Monoboron Complex

A reversible mechanochromic luminescent material based on a simple tetrahedral monoboron complex (B-1) is described. Interestingly, in addition to amorphous powders (P), the compound could exist in three unique crystal states (A, B, and C), showing efficient green-to-red luminescent colors, which is a result of wane and wax of dual emissions of the compound. Surprisingly, one of the emissions increases significantly with increasing temperature, fully offsetting the quenching effect of temperature-assisted internal conversion process. The four states are fully interconvertible through grinding and heating, allowing color writing/painting with a single ink
