Influence of matching solubility parameter of polymer matrix and CNT on electrical conductivity of CNT/rubber composite

Abstract: We report a general approach to fabricate elastomeric composites possessing high electrical conductivity for applications ranging from wireless charging interfaces to stretchable electronics. By using arbitrary nine kinds of rubbers as matrices, we experimentally demonstrate that the matching the solubility parameter of CNTs and the rubber matrix is important to achieve higher electrical conductivity in CNT/rubber composite, resulting in continuous conductive pathways leading to electrical conductivities as hi… Show more

“…1. Integrity of hexagonal structure of the MWCNT was confirmed by the presence of peak at 1533 cm −1 which evidences the existence of carbon double bond (C C) [21]. The spectrum showed absorption bands at 3437 cm −1 assigned to OH stretching.…”

“…The solubility parameters indicate the degree of interaction between materials. As mentioned in the Introduction, matching the solubility parameter of a carbon nanomaterial with the neighboring materials is the prerequisite to favor separation of the nanomaterial into individual particles [54] and to achieve ultimate dispersion in a polymer Unauthenticated Download Date | 5/12/18 9:50 AM matrix [57]. In this work, the dispersion of HSAG-PyC adduct in a solvent was inspected upon sonication and, in case of homogeneous dispersion (HSAG-PyC did not settle down or float on the solvent), was monitored also after 1 week storage at rest.…”

“…It has been shown [54] that a solvent able to minimize the Gibbs free energy of mixing with graphene and carbon nanotubes is able to promote the debundling of the tubes and the exfoliation of graphene aggregates. Moreover, matching the solubility parameters of polymer matrix and CNT leads to easier percolation of the nanofiller and Unauthenticated Download Date | 5/12/18 9:50 AM to larger electrical conductivity [57]. In the present work, the qualitative results of the dispersion tests were used to calculate the Hansen sphere for the HSAG adduct with the PyC based on dodecylamine, performing a first estimate of the Hansen solubility parameters (HSP) [58] of the adduct.…”

“…dispersive interactions (δ D ), polar interactions (δ P ) and hydrogen bonding interactions (δ H ) [33]. The dispersive Hansen parameter, δ D has an inverse relationship with the diameter of CNTs, since the former gets decided by the extent of van der Waals forces [33]. Therefore, it seems rational to mention that δ D becomes increasingly higher from pristine MWNTs to DWNTs, and further to SWNTs.…”

“…The Hansen solubility parameter (HSP), being important material property to illustrate the physicochemical compatibility of CNTs gets defined through the addition of three different contributing factors, viz. dispersive interactions (δ D ), polar interactions (δ P ) and hydrogen bonding interactions (δ H ) [33]. The dispersive Hansen parameter, δ D has an inverse relationship with the diameter of CNTs, since the former gets decided by the extent of van der Waals forces [33].…”
