Figure 5. Theoretical analysis: Cyclic performance of PDA@HNT composites for (A) pure PDMS, (B) 9 vol% of PDA@HNT at 1:4, (C) 15 vol% of PDA@HNT at 1:4, (D) 20 vol% of PDA@HNT at 1:4; and cyclic performance of (E and F) pure PDMS and (G and H) 20 vol% of PDA@HNT1:4 with improved stability and stretchability under applied stress.
