▎ 摘 要
Graphene foam (GF) infiltrated with polymer attracts researchers toward practical pressure sensing applications, especially tactile sensors. However, interface between polymer and graphene plays a vital role under a specific type and amount of pressure. Herein, we have investigated the impact of static and dynamic pressure upon GF-polymer. A recovery time of similar to 0.1 s is detected during static pressure sensing. Unlike static pressure, GF-polymer samples are highly sensitive to dynamic load, and a quick recovery time similar to 0.06 s is detected. The sensitivity of the dynamic pressure sensor similar to 1.17 +/- 0.1 Pa-1 is almost double compares to the sensitivity of the static pressure sensor similar to 2.1 +/- 0.3 Pa-1. Technologically, tactile sensors exert pressure in different forms and GF-polymer is an excellent choice for forming a pressure sensor. The present study will help develop efficient tactile sensors.
