Melting of Polymer-Polymer Composites by Particulate Heating Promoters and Electromagnetic Radiation

Experimental and computational conductivity study of multilayer graphene in polypropylene nanocomposites

“…All the nanocomposites were produced with the same processing conditions. The fillers were incorporated via masterbatch produced in a previous process where MLG loading of 15% were produced under the following optimized conditions [16]: highly dispersive screw configuration, 600 rpm and temperature profile 260 o C / 220 o C / 220 o C /210 o C / 200 o C / 190 o C. Masterbatch dilutions were processed with the same temperature profile with a screw speed of 800 rpm and using a highly dispersive screw. Samples were obtained by compression molding in a hot press (COLLIN model P200E) at 200 o C/15 bars during 15 min.…”

“…Previous experiments with Multiwall carbon nanotubes (MWCNT) [4] and multilayer graphene (MLG) nanoparticles have been performed over a polypropylene matrix; microwave heating has been used to estimate the effects of the filler in the polymer matrix [16], taking advantage of the fact that the polymer matrix exhibits a low dielectric loss in the GHz region [17]. Carbon nanotubes are more susceptible to microwave radiation than graphene multilayers, proving that graphene multilayers could be a better filler than the carbon nanotubes [18].…”

Single-polymer composites (SPCs): Status and future trends

“…Incorporation of suitable (nano)particles in the matrix or matrix-giving component acting as hot spots (heat sources) by external triggering (electromagnetic field, microwave etc.) seems to be a sound strategy [161,162]. To solve the quality assurance in line during production is also imperative.…”

Susceptor-assisted induction curing behaviour of a two component epoxy paste adhesive for aerospace applications

“…The susceptor particles are Iron particles, produced by Acros Organics, with an average size of 200 µm. These particles have been chosen because of their superior heat-generating properties compared to other susceptor materials, such as Nickel or Magnetite, as found in literature [10,16].…”

“…Research has shown that different susceptor particles show different heating characteristics [9]. Also susceptor-size and weight percentage have a significant impact [10,11]. In general, smaller sizes and higher particle content increase heat generation.…”
