Photografting - Wikipedia
网页Photografting is a technique used in the study of polymers and more in specific polymeric biomaterials. Technically speaking it is the covalent incorporation of functional additives to a polymer matrix or polymer surface using a light-induced mechanism.
Developments and new applications of UV-induced surface graft ...
网页2009年2月1日 · This article first reviews the various techniques to perform surface photografting polymerization from the perspectives of initiating method (different photoinitiators), effective controlling on the grafting (controlled/living grafting), self-initiated grafting (without the addition of photoinitiator), grafting systems containing a charge ...

Oxygen-Tolerant Photografting for Surface Structuring from …
网页2023年7月20日 · Here, we report an oxygen-tolerant photografting technique to grow polymer brushes employing microliter volumes of monomer solution under ambient conditions. With the key advantages that include spatial control, initiator/catalyst-free nature, and high oxygen tolerance, a series of homo-, multiblock, and arbitrary patterned polymer brushes were ...
Surface photografting of polymer fibers, films and sheets
网页1999年5月2日 · Surface photografting is a method for photoinitiated modification of polymer surfaces using UV irradiation, hydrogen abstracting photoinitiators and reactive vinyl monomers [1], [2] The method has been developed as a batch process and a continuous process and applied to fibers and films of …
Photografting and Patterning of Poly(ethylene glycol) …
网页An efficient procedure for chemical initiator-free, in situ synthesis of a functional polyethylene glycol methacrylate (PEG MA) hydrogel on regular glass substrates is reported. It is demonstrated ...
Photo-induced living/controlled surface radical ... - ScienceDirect
网页2011年9月1日 · Photo-induced living/controlled radical surface grafting polymerization. The photoreduction of aromatic ketones leads to the formation of a radical derived from the hydrogen donor and a radical produced from the carbonyl compound (ketyl type radical) in the presence of hydrogen donors.
