Abstract Straightforward and effective electrostatic charge detection would have significant importance for electronic assembly. Triboelectric charges arising from contact-separation between materials having different electron affinity causes damage of electronic components and devices valuable in billion dollars per year. In the present study we are demonstrating for the first time the visually perceptible vivid color to black transition in visible light absorbing nanowire colloids in viscous PDMS by nanowire directional alignment caused by electrostatic surface charges. The concept for triboelectric charge detection presented here does not require any power consumption or additional optical detection devices. The presented functional colloid is extremely simple, consisting from visible light absorbing nanowires in viscous polydimethylsiloxane (PDMS). There is no necessary to use photonic crystals, nanowires with monosize distributions of diameters and lengths or nanowires in well-ordered structures. Here the visually perceptible vivid color to black transition is observed in ZnO visible light absorbing nanowire colloids in viscous PDMS by nanowire directional alignment caused by electrostatic surface charges.
