Location-selective incorporation of multiwalled carbon nanotubes in polycarbonate microspheres

Effect of modified carbon nanotube on the properties of aromatic polyester nanocomposites

“…Currently, four processing techniques are in common use to fabricate CNT/polymer nanocomposites [34][35][36][37][38][39][40][41]: direct mixing, in situ polymerization, solution method, and melt compounding. Among these processing techniques, melt compounding has been accepted as the simplest and the most effective method from an industrial perspective, because this process makes it possible to fabricate high performance nanocomposites at low process cost, and facilitates commercial scale-up.…”

Dispersity and stability measurements of functionalized multiwalled carbon nanotubes in organic solvents

“…The weight loss of acid-treated MWCNTs was approximately 3.2 wt% from 150 to 400°C, indicating a 3.2 wt% content of carboxylic acid groups in these MWCNTs [16,17]. A weight decrease of 11.6 wt% from alkylated MWCNTs appeared from 280°C, decomposing the alkyl groups, to 470°C beginning to decompose the MWCNTs.…”

The processing of polycarbonate nanocomposites generated with various nanofillers

“…A network of MWNT agglomerates formed under shear leads to an increase of the electrical conductivity (Skipa et al, 2010;Alig et al, 2007), whereas the agglomeration reduces the shear modulus (G′ and G″) (Skipa et al, 2010). Jung et al (2008) developed a method to produce PC microspheres and incorporate multiwalled carbon nanotubes (MWCNTs) within them in the desired locations, called emulsion mixing. An oil-in-water (O/W) system consisting of two immiscible liquids, deionized water and methylene chloride, dissolves at room temperature poly (vinylpyrrolidone) (PVP) and PC, respectively.…”
