Influence the Fillers Orientation: A Short Review

“…The same pattern of electrical conductivity enhancement was reported using synthetic graphite (SG) fillers in liquid crystal polymer (LCP) compared to CF and CB fillers due to the fact that the fillers with high aspect ratio tended to orientate accordingly within the polymer matrix to provide a good electrical pathway [19]. The latest research reported that the fillers with high aspect ratio were used as the secondary fillers as their ability to fill the empty space of the primary fillers within the polymer matrix while developing an electrical network simultaneously [9].These showed that the high aspect ratio fillers have the Preprints (www.preprints.org) | NOT PEER-REVIEWED | Posted: 9 August 2018 doi:10.20944/preprints201808.0193.v1…”

“…However, these materials have a major drawback which deteriorates the performance of bipolar plate as a result of imbalance between the electrical conductivity and mechanical properties [3]. Thus, current research trends tend to use conductive polymer composite (CPC) as an alternative material due to its ability to enhance electrical conductivity while maintaining the mechanical properties of the material [9][10][11][12]. CPC materials are obtained by mixing the insulating material such as thermoplastic or thermoset material with conductive fillers such as carbon black, carbon nano-tubes (CNTs) and carbon fibre [3,13].…”

An optimization model of the input current for a variable input voltage in CMOS AC/DC converter

“…The circuit topology contains of two stages; boost converter in the input stage and a forward converter at the output stage. Both stages share the same switch, S1 [16].…”

“…The modeling of CMOS converter is designed using cadence circuit simulation tools. The results of simulation and post-layout are presented in paper [16]. The steady-state equation of the input current converter is derived in section III.…”
