Polyphenylene sulfide- expanded graphite nanocomposites

Journal of Thermoplastic Composite Materials, 2016
Polyphenylene sulfide (PPS)-expanded graphite (ExGr) conducting nanocomposites have been prepared by powder mixing and in situ polymerization routes after sonicating ExGr particles in acetone. Synthesized PPS has been used to make powder mixed composites.

Enhancement of the Fuel Regression Rate in Hybrid Propulsion by Expandable Graphite Additive

, 2020
Hybrid rockets can be an alternative to solid and liquid propellant systems, having improved safety, controllability, and high energetic performance. One of the features characterizing hybrid propulsion is a relatively low thrust due to low regression ...

Absorption Process of Expanded Graphite

2010 4th International Conference on Bioinformatics and Biomedical Engineering, 2010
Different expansion volume of expanded graphite was used for oil absorption experiments. The structure of expanded graphite was studied by scanning electron microscope (SEM) and optical microscope before oil-absorption and after oil-absorption. It was found that viscosity, expansion volume and particle size are the three key factors for the higher ...

Graining of thermo-expanded graphite

Materials Today: Proceedings, 2018
Abstract The results of investigation of the process of graining thermo-expanded graphite in the epicyclic granulator have been presented. Procedure of graining and the sequence of grains’ formation have been described. It has been obtained the experimental dependencies of the grains’ fractional distribution and their strength against epicyclic ωρ ...

Synthesis of few-layer N-doped graphene from expandable graphite with melamine and its application in supercapacitors

, 2020
In this paper, we introduced a novel method to prepare the few-layer nitrogen-doped graphene (FNG) from expandable graphite with melamine. The super-capacitive properties of FNG were thoroughly characterized by a three-electrode system, and the results ...

On lower-nitrogen expandable graphite

Materials Research Bulletin, 2000
Abstract The intercalation reaction of a mixture of HNO 3 and acetic anhydride to form expandable graphite was investigated. Expandable graphites were prepared from the intercalation compounds (GICs) by rapid heating up to 900°C. The effects of reaction conditions on the quality of the expandable graphites were studied and the optimum conditions for

Expanded graphite offers new opportunities

Plastics, Additives and Compounding, 2008
Graphite has been overlooked in the past as additive for polymers. C. Ciallella, T.M. Gruenberger, E. Grivei and N. Probst of Timcal explain why a reconsideration is required.

Suppression of aluminum dust explosions by expandable graphite

, 2020
The suppression effect of expandable graphites (EGs) on 5 μm aluminum dust explosions was systematically studied in an open-space dust apparatus. Flame propagation behaviors showed that flame structures became more discrete and more irregular after the ...

Flame retardant, mechanical and thermal insulating properties of rigid polyurethane foam modified by nano zirconium amino-tris-(methylenephosphonate) and expandable graphite

, 2019
A novel phosphorus-nitrogen flame retardant, nano zirconium amino-tris-(methylenephosphonate) (Zr-AMP), successfully synthesized by allowing amino trimethylene phosphonic acid (AMP) to react with ZrOCl·8H2O, was incorporated into rigid polyurethane (RPU)

Preparation of highly dispersed expandable graphite/polystyrene composite foam via suspension polymerization with enhanced fire retardation

Carbon, 2019
Expandable graphite (EG) is a common carbon-based fire retardant material. However, its low compatibility and tendency of agglomeration in polymeric material limit its application and potential efficiency.
