A polymeric material can be functionalized by the addition of small moieties, oligomers, and even other polymers (grafting copolymers) onto the surface or interface. Grafting, in the context of polymer chemistry, refers to the addition of polymer chains onto a surface. In the so-called 'grafting onto' mechanism, a polymer c… WebJan 9, 2024 · Covalent organic framework (COF) as a kind of crystalline porous material possesses intriguing advantages, including low density, large surface area, permanent porosity, and excellent chemical stability.

The grafting through, also known as the macromonomer method, is one of the simpler ways of synthesizing a graft polymer with well defined side chains. Typically a monomer of a lower molecular weight is copolymerized with free radicals with an acrylate functionalized macromonomer. See more In polymer chemistry, graft polymers are segmented copolymers with a linear backbone of one composite and randomly distributed branches of another composite. The picture labeled "graft polymer" shows how grafted chains … See more There are many different approaches to synthesizing graft copolymers. Usually they employ familiar polymerization techniques that are commonly used such as atom transfer radical polymerization (ATRP), ring-opening metathesis polymerization See more Graft copolymers are a branched copolymer where the components of the side chain are structurally different than that of the main … See more Graft copolymers became widely studied due to their increased number of applications like in drug delivery vehicles, surfactants, water filtration, rheology modifiers, etc. It is … See more WebAug 31, 2024 · Definition Grafting is an advanced technique that botanists, farmers, gardeners, and hobbyists use to add living tissue from one plant to another.
