Core/shell silicon/polyaniline particles via in-flight plasma-induced polymerization

Advances and challenges in the field of plasma polymer nanoparticles

“…The second strategy relies on spatial separation of the formation of metal NPs and their embedding into polymer or plasma polymer shells, similar to what has been realized in [ 72 – 73 ]. This strategy allows the decoupling of the processes of magnetron sputtering and plasma polymerization and may prove advantageous, especially if more reactive metals are considered.…”

Critical barriers to the large scale commercialization of silicon-containing batteries

“…with silicon particles grown in a first low-temperature plasma from silane and then aerodynamically injected into a second low-temperature plasma where the surface modification takes place. Yasar-Inceoglu et al 120 have demonstrated this for the case of polyaniline, which can be grafted conformally and in-flight onto silicon particles via the plasma-induced polymerization of aniline. Coleman et al 131 applied the same concept using methane as precursor in place of aniline, resulting in an amorphous carbon shell although care has to be taken to avoid carbonization and formation of silicon carbide crystals in the second plasma.…”

“…Plasmas have also been extensively used to supply silicon particles to groups actively researching silicon-based anodes. 58,59,[117][118][119][120] The term plasma refers to an ionized gas and covers a very broad range of systems. In general, plasmas can be categorized as thermal (i.e.…”

Phase composition and growth mechanisms of half-metal Heusler alloy produced by Pulsed Laser Deposition: From core-shell nanoparticles to amorphous randomic clusters

“…shell ratio 7:2 -this specific nanoparticle has a total diameter of 32 nm (corresponding to 17,150 nm 3 ), while the core has a diameter of 21 nm (corresponding to 4,850 nm 3 ). The thickness of the amorphous shell, close to 5.5 nm, exceeds the typical thickness for a native oxide layer growth at room temperature (∼ 1 nm) [24]. High magnification images were acquired, as presented on Fig.5(a).…”
