Scalable, solvent-less de-bundling of single-wall carbon nanotube into elastomers for high conductive functionality

Features and Application of Carbon Nanotube and Rubber Composites

“…Of the above, use of a solvent to disperse the CNT as in (1) and (2) achieves good defibration [5]. In particular, technique (1) necessitates dispersal of hydrophobic CNT in the aqueous emulsion polymerisate and the use of surfactant is therefore essential.…”

Dispersion stability of chemically reduced graphene oxide nanoribbons in organic solvents

“…Nanostructured sp 2 carbon allotropes, such as fullerene, carbon nanotubes (CNTs), and graphene, have attracted considerable attention in numerous scientic elds over the last few decades. These allotropes have applications in electronics, [1][2][3][4] optics, [5][6][7] energy storage/conversion, [8][9][10][11][12] catalysis, [13][14][15] polymer composites, [16][17][18][19][20][21] actuators, 22,23 and sensing 24,25 because of their unusual properties and nanometre-scale effects. Graphene nanoribbons, one type of nanostructured sp 2 carbon allotrope, are ultra-thin strips of graphene containing numerous edge/defect sites with outstanding electronic and spin transport properties.…”

Conductive, sensing stable and mechanical robust silicone rubber composites for large‐strain sensors

“…Single-wall CNTs (SWCNTs) are highly suitable for preparation of high performance CPCs due to their thermal and chemical stability and less surface defects besides high electrical conductivity. [16] When CPCs with CNTs suffer the strain, their conductive networks will be reconstructed, which leads to a partial disruption of contacts or increase in the distances between neighbored nanotubes above the tunneling or hopping distances and macroscopically an electrical resistance increase (i.e., sensing response). [17][18][19][20][21][22] But CNTs are always difficult to disperse in the polymer matrix although some advanced processing technologies have been performed, such as solution casting method.…”

“…[17][18][19][20][21][22] But CNTs are always difficult to disperse in the polymer matrix although some advanced processing technologies have been performed, such as solution casting method. [16] In contrast with multi-wall CNTs, SWCNTs suffer more serious dispersability problems in most rubbers due to stronger van der Waals force besides their more expensive costs, which results in few experimental reports about SWCNT/rubber composites. [8] Especially, the dispersion of SWCNTs would become worst on condition that high conductivity of CPCs was practically needed.…”
