Identifying a Unique Communication Mechanism of Thermochromic Liquid Crystal Printing Ink

Preparation of Reversible Thermochromic Ink for Flexography Printing on Paper and Study its Colorimetric Properties

Thermochromic printing inks could be security inks which respond to the color change when are being exposed to different temperatures. These inks with unusual chemical and physical specific characteristics are mostly produced for flexographic, screen and rotogravure printing systems under the supervision of skilled technical experts and with precise security controls. Since flexographic thermoc...

Errors in thermochromic liquid crystal thermometry

This article experimentally investigates and assesses the errors that may be incurred in the hue-based thermochromic liquid crystal thermochromic liquid crystal (TLC) method, and their causes. The errors include response time, hysteresis, aging, surrounding illumination disturbance, direct illumination and viewing angle, amount of light into the camera, TLC thickness, digital resolution of the ...

Columnar liquid crystal as a unique ferroelectric liquid crystal

Personal electronics printing via tapping mode composite liquid metal ink delivery and adhesion mechanism

Printed electronics is becoming increasingly important in a variety of newly emerging areas. However, restricted to the rather limited conductive inks and available printing strategies, the current electronics manufacture is usually confined to industry level. Here, we show a highly cost-effective and entirely automatic printing way towards personal electronics making, through introducing a tap...
