Figure 4. (A) The relative resistance change R/R0 of the PDA@HNT/rGO/PDMS aerogel composites vs. strain, (B) ΔR/R0 and GF values under applied strain, (C) sensing performance of gauge factor at different HNT/GO ratios, (D) maximum percentage of sensing range and range of linearity at different ratios (PDA@HNT to GO) of samples.
