Experimental study on the thermal and mechanical properties of MWCNT/polymer and Cu/polymer composites

From morphology of attrited copper/MWCNT hybrid fillers to thermal and mechanical characteristics of their respective polymer‐matrix composites: An analytical and experimental study

“…As expected, increase of the milling load will result in the length reduction of the nanotubes (see Figure and Ref. ). In other words, cutting the MWCNTs to a shorter length enhances the distribution of the particles through the polymer‐matrix which could significantly influence the thermal and mechanical properties of the composite.…”

“…As for the mechanical analysis, dogbone (ASTM D638) and simple cuboid‐shape (35 × 10 × 2 mm 3 ) specimens were prepared for the measurement of tensile strength and temperature‐related viscoelastic characteristics, respectively. After 20 min of compression, the specimens were removed from the hot press and gradually cooled to the room temperature to minimize the formation of the amorphous phase in the polymer structure …”

The relevance of material and processing parameters on the thermal conductivity of thermoplastic composites

“…Nikhil et al showed that composites with gold nanofibers can display a TC of 5 W m −1 K −1 , even at filler amounts as low as 3 m%. Park et al indicated that by changing the shape of copper from sphere‐like to flake‐like an increase in TC can be noticed as well.…”

“…Equipments such as a ball mill can improve contact between filler and polymer. Despite this inherent poor dispersion, creative use of these techniques can provide quite good results by changing the shape of the filler, which as explained above allows to alter the TC . Too long mixing times result, however, in too small particles and a lower TC .…”

Research into kinetic patterns of chemical metallization of powder­like polyvinylchloride

“…Polymeric materials with conductive fillers comprise a separate group of highly technological composites, research into which has recently attracted much attention [3][4][5][6][7]. A combination of the polymer and such fillers sets the aim to receive new materials, which are characterized by a set of unique properties and have considerable potential for practical application.…”
