“…For example, butyl groups are more effective in reducing interfacial thermal resistance compared to carboxyl and hydroxyl according to molecular dynamic simulation 266 . However, the covalent modification of the carbon surface induces the hybridisation from sp 2 to sp 3 reducing conjugated bonds and lowering its electrical properties 267 Depending on the stiffness of the polymer backbone, the aromatic conjugated polymer chains may create a helical wrap around the lateral side of the carbon nanotubes throughinteractions. The wrapping mechanism occurs when the number of polymer units interacting with the nanotube surface at the expense of some torsional energy necessary to distort are sufficient.…”

The recent development of nanoscale fillers, such as carbon nanotube, graphene, and nanocellulose, allows the functionality of polymer nanocomposites to be controlled and enhanced. However, conventional synthesis methods of polymer nanocomposites cannot maximise the reinforcement of these nanofillers at high filler content. Approaches to the synthesis of high content filler polymer nanocomposites are suggested to facilitate future applications. The fabrication methods address design of the polymer nanocomposite architecture, which encompass one, two, and three dimensional morphology. Factors that hamper the reinforcement of nanostructures, such as alignment, dispersion of filler as well as interfacial bonding between filler and polymer are outlined. Using suitable approaches, maximum potential reinforcement of nanoscale filler can be anticipated without limitations in orientation, dispersion, and the integrity of the filler particle-matrix interface. High filler content polymer composites containing emerging materials such as 2D transition metal carbides, nitrides, and carbonitrides (MXenes) are expected in the future.Graphical abstract: Approaches to the synthesis of high filler content polymer composites

“…In particular, nanocomposites not only have remarkable properties that can be tailored for broad application in many fields, but their processability is also simple. Nanocomposites could help the development of light-weight structural materials and functional materials (Park and Seo, 2012;Mittal et al, 2015;Chen et al, 2018;Mohan et al, 2018). One interesting possibility offered by functional nanocomposites is to exploit their piezoelectric response for structural health monitoring (SHM) (Pegoretti, 2019).…”

Fused Filament Fabrication of Piezoresistive Carbon Nanotubes Nanocomposites for Strain Monitoring

2020

Conductive carbon nanotubes (CNT)/acrylonitrile butadiene styrene (ABS) nanocomposites parts were easily and successfully manufactured by fused filament fabrication (FFF) starting from composite filaments properly extruded at a laboratory scale. Specific specimens for strain monitoring application were properly evaluated in both short term and long term mechanical testing. In particular, samples of ABS filled with 6 wt.% of CNT were additively manufactured in two different infill patterns: HC (0 • /0 • ) and H45 (−45 • /+45 • ). The piezoresistivity behavior was investigated under various loading conditions such as ramp tensile tests at different rate and extension, and also creep and cyclic loading at room temperature. Experimental work revealed that the resistance changes in the conductive samples were properly detectable during stress or strain modification, as consequence of damage and/or reassembling of the percolation network. The measurement of the gauge factor in various testing conditions evidenced an initial higher sensitivity of the 3D-built parts within H45 pattern in comparison to the correspondent HC counterparts. The CNT conductive network path in the investigated samples seems to be reformed during creep and cycling experiments, showing a progressive reduction of gauge factor that seems to stabilize at about 2.5 for both HC and H45 samples after long term testing. These findings suggest that conductive CNT/ABS nanocomposites at 6 wt.% of loading can be successfully processed by FFF to produce stable strain sensors in the range −25 • and +60 • C, as confirmed by the constancy of resistivity in these temperatures.

“…[39][40][41][42] However, the carbon nanotube-polymer interface is oen weak and the long-range structure of the polymer segment is hard to control. 43 For example, a prior study demonstrated that one polymer could displace another on a SWNT surface. 44 The competitive binding between SWNTs and different polymers, along with the potential for the interpenetration of polymer layers, complicate the implementation of this strategy to construct ordered nanostructures comprised of multiple, self-sorted components.…”
