Abstract—In this study, multi-functional tannic acid (TA) was incorporated with soft poly(propylene oxide) (PPO) chain to result in a TA-terminated JTA polymer, in which the TA terminals impart reversible aromatic p-p and hydrogen bond (H bond) interactions to JTA polymer. Moreover, the aromatic TA terminals of JTA can preferably bind to the surface carbon rings of multi-walled carbon nanotubes (MWCNTs) to result in JCTx composites containing large amounts (up to 96 wt%) of MWCNTs. The sorption isotherm study indicated a two-step sorption mechanism of the sorbed JTA on MWCNT. Dependent on the MWCNT content, JCTx composites can be healable elastomers with high fracture strain (up to 700%) or plastics with outstanding conductivity (up to 1.21×106 m-1). Experimental mechanical modulus and conductivity of JCTx also were approached by the theoretical Kolarik model and scaling law, respectively. The result was explained in term of morphological arrangement of the MWCNT, evaluated from scanning and transmission) electron microscopies in JTA matrix. This study provided theoretical evaluation of highly MWCNT-loaded composites.
Keywords—Tannic acid, MWCNT, carbon material dispersion, p-p stacking, hydrogen bonding, conductive composite, Kolarik model, scaling law.
