The development of a conductive carbon nanotube (CNT) network in CNT/polypropylene composite films during biaxial stretching

Surface Modification of Carbon Nanotubes for High-Performance Polymer Composites

“…2.11, Young's modulus and tensile strength considerably increase in the presence of nanotubes. Various results were observed by other researchers for PP/CNT composites [52,[63][64][65].…”

“…With the surfactant (C 12 EO 8 ) as the processing aid, the addition of only 1 wt% CNTs in the composite increases the glass transition temperature (T g ) from 63 C to 88 C, as shown in Table 2.1. Miyagawa and Drzal [17] reported on the thermophysical properties and impact strength of diglycidyl ether of bisphenol F epoxy nanocomposites reinforced with fluorinated SWCNTs (FSWCNTs).…”

Micromechanics Modeling of Bi-Axial Stretching Effects on the Electrical Conductivity of CNT-Polymer Composites

“…Nevertheless, bi-axial stretching is another typical stretching mode for CNT-polymer composites [Shen et al, 2012;Mayoral et al, 2013], which enables the CNTs to re-orientate along the two stretching directions in the polymer matrix. Such a stretching mode is expected to reduce the anisotropy of the electrical properties of the composites in the stretching plane compared to the uni-axial stretching case in which the CNTs are prone to get parallel along the uni-axial stretching direction.…”

Effect of high temperature, biaxial stretching on the thermal and mechanical properties of HDPE/MWCNT sheet

“…The effect of uniaxial stretching on the structure and properties of polymer/CNT composites has been extensively investigated [9,10,11]. However, few investigations on the effect of biaxial stretching on polymer/CNT composites have been carried out [1,12]. In this present study, the high temperature, biaxial stretching of a high density polyethylene (HDPE) based MWCNT nanocomposite is conducted.…”

“…[1,2]. The processing route to produce a product can have an important influence on the structure [3,4] and final properties [5,6] and, changes in material thermal and rheological properties due to the addition of nanoparticles can also significantly alter processability [7,8].…”
