Effect of surfactant concentration on the evaporation-driven deposition of carbon nanotubes: from coffee-ring effect to strain sensing

Abstract: Our discovery reveals the existence of an optimum SDS/CNT concentration ratio to achieve the highest conductivity of ring deposition for strain sensing.

“…The weights of the CNTs and SDS were measured using an A&D HR-200 analytical balance with a precision of 0.1 mg. According to our recent work, 15 the optimum concentration ratio for SDS and CNTs to achieve the best deposition in terms of density and conductivity is 1 : 1. Considering the concentration of 0.4 wt% for both of them, the CNTs and SDS were dispersed in deionized water.…”

“…In the second case, the conductivity of the printed pattern is considerably dependent on the density of the deposited CNTs, and alignment is not as critical. 15 There is an inverse correlation between the density of the accumulated CNTs and their electrical resistance. 15…”
