چکیده

In this study unfunctionalized expanded graphite (EG) was incorporated into poly(ether ether ketone) (PEEK) using twin-screw extrusion and injection moulding to manufacture cost-effective PEEK/EG composites for mass production of high-performance antistatic materials. Direct current electrical conductivity, morphology, rheological thermal properties the were investigated. At an EG loading 5 vol%, conductivity exhibited abrupt increase 1.45 × 10?5 S m?1 which in required range The frequency dependence storage modulus melt containing 2 vol% decreased significantly at low frequencies. Viscosity did not much with addition comparison other nanofillers such as carbon nanotubes. crystallinity PEEK increased 41.11% from 35.87% upon 3 EG. improved stability by initiation temperature its decomposition steps. © 2021 Authors.

‏‎faciliting lexical access for the fluent production of speech‎‏

‏‎the hypothesis is that recent and frequent exposure to lexical items leads to a more fluent production of speech in terms of rate of speech. to test the hypothesis,a one-way anova experimental design was carried out. 24 sednior students of efl participated in a one-way interview test. data analyses revealed that those who were exposed frequently to the lexical items over a week prior to inter...

Dispersion of graphite nanoplates during melt mixing

Graphite nanoplates (GnPs) are exfoliated graphite particles in the form of thin flakes—with large surface areas and nanosized thicknesses— that tend to agglomerate because of van der Waals interactions. GnPs are commonly used to reinforce composite materials. It is expected that maximum composite performance levels should occur when GnP agglomerates are dispersed within the polymer matrix as p...

Poly(allyl glycidyl ether)-A versatile and functional polyether platform.

Allyl glycidyl ether, polymerized from potassium alkoxide/naphthalenide initiators under both neat and solution conditions was shown to be a highly-controlled process. In both cases, molar masses (10-100 kg/mol) were determined by the reaction stoichiometry, and low polydispersity indices (1.05-1.33) could be obtained with a full understanding of the dominant side reaction, isomerization of the...
