TL;DR: Several reaction mechanisms have been proposed for the formation of plasma polymers, such as monomer fragmentation followed by poly-recombination into randomly structured and crosslinked films; fragmentation, accompanied by formation of acetylene or other film-forming intermediates and deposition of polystyrene-like material; plasma-initiation of a radical chain-growth polymerization; and ion-molecule reactions, as well as ionic chain growth polymerization as discussed by the authors.

TL;DR: In this article, a pulsed plasma was used to initiate chemical copolymerization of allyl alcohol and styrene, and the concentration of OH groups at the surface of the copolymers layer could be adjusted from 0 (styrene homopolymerization) to 31 OH groups/100 C atoms.

TL;DR: In this paper, a modified polymer surface with a high density and homogeneity of hydroxyl groups was chemically reduced by diborane and LiAlH4 with yields of 10 to 11 OH groups per 100 carbon atoms in the 3 to 5 nm near-surface layer.

TL;DR: Plasma-chemical bromination has been shown to be wellsuited for highly selective and efficient C-Br-functionalization of polyolefin surfaces and has now been applied to graphitic materials, including highly oriented pyrolytic graphite (HOPG), natural graphite, carbon nanotubes, and graphitized carbon fibres as discussed by the authors.
