An electrogenerated poly(pyrrole-benzophenone) film for the photografting of proteins

Chemical Communications, 2003
A photoreactive organic polymer was prepared by oxidative electrochemical polymerization of a pyrrole-benzophenone derivative on conductive surfaces; the resulting polypyrrolic film allowed, upon irradiation, the reagentless covalent grafting of proteins.

Biomimetic apatite formation on polyethylene photografted with vinyltrimethoxysilane and hydrolyzed

Biomaterials, 2001
A photografting technique to produce functional groups of silanol able to induce apatite nucleation was attempted on polyethylene substrate for biomimetic formation of bone-mineral-like apatite layer on its surface. The polyethylene surface was subjected to vapor-phase photografting of vinyltrimethoxysilane and subsequently to hydrolysis.

Photografting of p-anisidine-glycidyl methacrylate onto polymeric substrate for developing free-radical scavenging films

, 2020
In this study, we present a facile approach for the development of a non-migratory antioxidant film via photografting of a conducing polymer (p-anisidine (PA)) onto polypropylene (PP).

Synthesis and characterisation of some new photografted polycarbonates

Polymer Photochemistry, 1984
Abstract Several copolycarbonates of bisphenol-A (I) and 1,1,1-trichloro-2,2-bis(4-hydroxyphenyl ethane) (II) containing different percentages of II have been prepared. Acrylonitrile monomer has been successfully grafted on these copolymers via the chlorinated group (−CCl 3 ) by photochemical reaction using Mn 2 (CO) 10 as a catalyst in the presence

Surface modification and lamination of polymers by photografting

International Journal of Adhesion and Adhesives, 1999
This paper describes experimental processes for UV initiated “surface photografting” of polymers: the batch process with vapor-phase transfer of initiator and monomer and the continuous process with liquid-phase transfer of initiator and monomer in a thin layer of solution on the surface of the substrate.

Modification of adhesive properties of a polyethylene film by photografting

Journal of Applied Polymer Science, 2004
AbstractGraft polymerization of acrylic acid from monomer solutions in water or in bulk onto low‐density polyethylene film substrate was carried out by the method of continuous process under UV radiation. Effects of the nature of photoinitiator on acrylic acid grafting was first studied. One PI2 and two PI1 photoinitiators were used.

Photografting Graphene Oxide to Inert Membrane Materials to Impart Antibacterial Activity

Environmental Science and Technology Letters, 2019
Surface modification with bactericides is a promising approach to imparting membrane materials with biofouling resistance. However, chemical modification of membranes made from inert materials, such as polyvinylidene fluoride (PVDF) and polysulfone, is ...

Thermally Regenerable Ion-Exchange Resins by Photografting

Journal of Macromolecular Science: Part A - Chemistry, 1977
Abstract Crosslinked polymer beads containing regions of acidic and basic groups are the preferred structures for the efficient operation of a thermally regenerable ion-exchange process. Such systems can be prepared by various methods. Here the approach of using polymers and copolymers containing photo-labile groups as grafting sites is described.
