“…This indicates that PP composites achieve a stabilization effect through the barrier effect of filler loading, which hinders volatilization of bulk samples into gas phase. 22 TGA curves reveal that composites are stable at up to 350 C, with weight reduction of around 0.5%. The TGA profile can be clearly depicted by the derivative weight % (DTG) curve in Figure 8.…”

We investigated the effects of various fillers such as carbon nanotube (CNT), synthetic diamond (SND), boron nitride (BN), and copper (Cu) on the properties of polypropylene (PP) composites. The thermal conductivity and stability of PP were enhanced upon the addition of thermally conductive fillers. Young's modulus increased with filler loading, while tensile strength increased at up to 2 vol.% then decreased with elongation in all filler types. The morphology of the composite samples showed agglomeration and void content in PP/Cu composites, leading to the deterioration of thermal and mechanical properties at high-volume loading. Findings indicate that PP/ CNT has better thermal and mechanical properties compared with the other types of fillers.

“…The maximum electrical conductivity of 2.1 S/cm was obtained when 15 wt% MWCNTs was added to an ABS base LTCC, while that of pure ABS was only ~10 −6 S/cm. The percolation threshold exists at the 2.5-5 wt% MWCNTs added region owing to the uniform dispersion of MWCNTs up to 10 wt%, which is a relatively higher loading rate than others [48] (Figure 15).…”

Recently, ceramic substrates have been of great interest for use in light emitting diode (LED) packaging materials because of their excellent heat transfer capability. The thermal conductivities of ceramic-based substrates are usually one or two orders of magnitude higher than those of conventional epoxy-based substrates. The demand for ceramic substrates with high mechanical strength and thermal conductivity is also growing due to their use in thin and high-power device packaging substrates. Examples are direct bonded copper or aluminum or direct plated copper substrates for insulated gate bipolar transistors; thin and robust ceramic packages for image sensor modules that are used in mobile smart phones; ceramic packages for miniaturized chip-type supercapacitors; and high-power LED packages. This chapter will cover the development and application of ceramics and ceramic composites with high thermal conductivity for the thermal management of integrated electronic packaging substrates such as high-power LED packaging, power device packaging, etc.

“…There have been many attempts during the last 20 years to take advantage of the excellent properties offered by individual carbon nanotubes (CNT) by incorporating them in composites [1]. With glass or ceramic matrices, improvements in properties such as wear resistance [2,3] and electrical and thermal conductivity [4,5] have been reported but most attention has been focused on mechanical properties. Most studies have investigated randomly orientated CNTs within matrix [6,7] but these composites have shown only modest improvements in stiffness and toughness [8,9].…”

Stiffness, strength and interwall sliding in aligned and continuous multi-walled carbon nanotube/glass composite microcantilevers

Individual perfect multi-wall carbon nanotubes (MWCNT) can exhibit exceptional properties, such as an elastic modulus of ~1 TPa. However, integration of carbon nanotubes (CNTs) in bulk ceramic composites has not yet resulted in the significant improvements in mechanical properties that such data suggest to be achievable. Composites with aligned and continuous CNTs and with high CNT volume fractions might be expected to maximise the improvements. We have produced aligned MWCNT preforms by chemical vapour deposition and fabricated dense, aligned and continuous 20% MWCNT/glass composites. This was achieved by infiltration of a ceramic precursor sol into the interstices of a MWCNT preform and consolidation by hot-pressing. The elastic modulus was measured using microcantilever tests and showed a 32% improvement over that of glass. The Young's modulus inferred for the MWCNTs in the composite was 200 ± 20 GPa. The load-displacement curves showed a nonlinear and hysteretic behaviour which was attributed to interwall sliding within the MWCNTs. Apparent bridging of the cracks by the MWCNTs and a load maximum preceding failure
