Grafting of poly(methyl vinyl ketone) onto aluminum surface

Grafting of Poly(acrylic acid) onto an Aluminum Surface

“…C, Al, and O were detected in all samples, and Si was detected in those which were modified with allyltrimethoxysilane (Tables and ). Carbon contamination was detected in pristine aluminum (p-Al) and in activated aluminum (Al−OH) substrates, as previously reported . Therefore, the carbon signal coming from that contamination is probably superposed in “silanized” and polymer-covered surfaces to the carbon peaks arising from chemically bound molecules.…”

“…Aluminum discs with a diameter of 32 mm and a thickness of 2 mm were polished in a Struers polisher to yield mirror-like surfaces. Comparative nonpolished disks were also used to produce rough surfaces.…”

“…To improve the durability of the polymer on the metallic surface, traditional methods for covalently anchoring polymers to oxide surfaces of the metals were developed. Such methods include the “grafted from” with initiators − or monomers , initially anchored to the surface or the “grafted onto”, where a preformed polymer is covalently linked to the surface. , A great variety of polymers have been successfully anchored to inorganic surfaces by such methods. In particular, poly(acrylic acid) (PAA) has been grafted via reversible addition−fragmentation chain-transfer (RAFT) living polymerization onto TiO 2 nanoparticles, by electrochemical polymerization onto titanium substrates, with gradual variation of chain grafting densities on flat silica, and as hyperbranched PAA onto both gold surfaces and gold-coated porous alumina supports .…”

Poly(Vinyl Ketones): New Directions in Photodegradable Polymers

“…[ 71 ] Veith and coworkers grafted PMVK onto aluminum surfaces to modify the chemical and physical properties of the interface. [ 72 ] Furthermore, active ATRP initiating sites on solid particles such as crosslinked PS/PMVK microspheres can be generated by regioselective peroxybromination of PMVK by using hydrogen peroxide (H 2 O 2 ) on sodium bromide (NaBr) in acidic media. [ 74 ]…”

Biodegradable polymer brush as nanocoupled interface for improving the durability of polymer coating on metal surface

“…The activated surface of the pretreated Co-Cr might lead to an effective interaction between the trimethoxysilyl group of BTPAm (initiator) and the hydroxyl groups on the surface. Trimethoxysilyl group is known as a strong binder of various metal surfaces such as silicon [28], stainless steel [29], titanium alloy [30], and aluminum [31]. The PHEMA brushes were designed for high density of hydroxyl groups that are useful for post-modification step including ROP of l-lactide (l-form) in order to synthesize stereoisomeric PLLA-graft onto Co-Cr surface.…”
