Extended Data Fig. 8: Control devices made of porous PTFE, PDMS and PP.
From: A droplet-based electricity generator with high instantaneous power density
Comparison of the maximum stable surface charge, Qmax, on control devices made of porous PTFE, PDMS and polypropylene (PP) after continuous droplet impact under a relative humidity of 65.0%; all of these charges are much smaller than that of our DEG surface.
