Advanced Dispersion Strategies of Carbon Nanofillers and their use to enhance Mechanical and Electrical Properties of Polyacrylonitrile Fibers
… of polyacrylonitrile fibers containing carbon nanofillers, namely carbon nanotubes (CNTs) and carbon black (CB). Mechanically strong and electrically conducting poly(acrylonitrile) (PAN) fibers were obtained by incorporating up to (a) 15 wt% single wall carbon nanotubes (SWNTs) and (b) …

Thermal Degradation of PC and PA6 During Laser Transmission Welding (LTW)
… the laser-transparent part and is absorbed by carbon black (CB) in the laser-absorbent part. This causes a temperature rise at the interface between the parts which leads to melting, diffusion and ultimately joining of the two components. Weld temperatures increase with laser power at a given …

Structure-Property Evaluation of the Dielectric Properties of Radar Absorbing Materials in Free Space
… graphite powder (GP), iron powder (CIP), and carbon black (CB), at varying loading levels to understand the structure-property relationships that affect dielectric properties in Free Space and anechoic chamber measurements. We hypothesized that the implementation of shaping of the composite …

Development and characterization of electrically conductive thermoplastic based composite materials for fuel cell bipolar plates
… of fuel cell bipolar plates. Graphite, Carbon Fiber (CF), Multi-walled Carbon Nanotubes (MWCNT), Carbon Black (CB), and Expanded Graphite (EG) were used as conductive fillers. These fillers were added to three different polymer matrices: Polypropylene (PP), Nylon, and Thermoplastic …

Design and Performance of Intrinsic Self-sensing Cementitious Composites for Smart Structural Health Monitoring of Civil Infrastructure
… and many positive developments on fibrous carbon materials filled self-sensing cementitious composites, the development and application of self-sensing cementitious composites filled with carbon black are still limited either by the low sensing effectiveness or the inferior mechanical …

Soft nanocomposites with enhanced electromechanical response for dielectric elastomer actuators
… that the use of nanofiller conductive particles (carbon black (CB)) can lead to a strong increase of relative permittivity through percolation, however, with detrimental side effects. These are due to localized enhancement of the electric field within the composite, which leads to sharp reductions …

Redox-responsive polymers for the reversible extraction of butanol from water
… by the application of electric potential. Carbon black (CB) and carbon fiber mats, called carbon paper (CP) were used as the substrates. RPEs were prepared using five different techniques-three techniques were based on strategies reported in literature and involved the chemical modification …

Ultrasonically Aided Extrusion of Rubber Nanocomposites and Rubber Blends
… butadiene rubber (SBR) compounds filled with carbon black (CB), carbon nanotube (CNT) and carbon nanofiber (CNF) and NR/SBR blends. The ultrasonic treatment was found to provide a better processibility leading to a significant reduction of the die pressure during extrusion. For SBR …

Avalanches, percolation, and stochastic damage evolution in disordered media
… adding marginal amounts of nanofillers such as carbon nanotubes (CNTs), graphene nanoplatelets (GNPs), and carbon black (CB). This phenomenon is induced by the formation of a percolating network of nanofillers interconnected electrically by the quantum tunneling effect. A continuum percolation …
