14/8/2020· Carbon nanofibers and nanotubes are promising to revolutionise several fields in material science and are a major component of nanotechnology. Further market development will depend on material availability at reasonable prices. Nanotubes have a wide range of
The nonisothermal melt crystallization kinetic analysis suggested that GN served as a nucleating agent and could considerably promote the PLA’s crystallization through heterogeneous nucleation. Our findings suggested that at relatively low cooling rates ( ϕ ≤ 10 °C/min) even a small amount of GN promoted the nucleation and considerably increased the crystallization rate.
N,N′-Dicyclohexyl-1,5-diamino-2,6-naphthalenedicarboxamide (NA), a highly efficient and selective β-nucleating agent for isotactic polypropylene (iPP), was synthesized and chemically supported on the surface of multiwall carbon nanotubes (MWCNTs) via an
nucleating agent on the crystalline structure and mechanical properties of the PP were also explored. A multi-walled carbon nanotude (MWCNT) supported nucleating agent was introduced to modify the crystalline structure of PP and the impact strength of the
TiC nanoparticles are excellent conductors, resistant to wear and corrosion, and are chemically inert. TiC is used in the manufacturing of wear-resistant tools, in a variety of optics appliions, as a nucleating agent, and as an additive that enhances conductivity.
A propylene/ethylene polymeric matrix was reinforced by the simultaneous addition of a β-nucleating agent (calcium pimelate) and multi-walled carbon nanotubes (MWCNTs) in various concentrations. The present manuscript explores the competitive crystallization tendency …
Reaction-induced crystallization of oligomers was applied for the preparation of single-walled carbon nanotubes (SWNTs)/poly(p oxybenzoyl) (POB) crystals using SWNTs as a nucleating agent. The research, detailed in the publiions and prior technical reports, is larger than 2 .

Carbon nanotubes (CNTs) based polymer composites have variety of engineering appliions (electromagnetic shielding, antistatic coatings, high-strength low-density corrosion-resistant components, lightweight energy storage and many more); due to their excellent
X-ray diffraction showed that the alpha type crystallinity remains, irrespective of the nucleating agent. Finally, the intensity ratio between the (040) (at 16.7°) and the (110) (at 13.9°) reflections increased, which was taken as an indiion of an increasing nucleating efficiency.
Moreover, we find that various other compounds, including C-70 fullerene, single-walled carbon nanotubes, and sodium benzoate, as well as a nuer of commercial nucleating agents-commonly used to clarify isotactic polypropylene-permit to control
