Even a … WitrynaThe cross-linker agent controls the structure of the polymer matrix in molecularly imprinted polymers, in which such agents lead to aggregation and connection of functional monomers to each other and stand firmly in own place and polymerization and molecular template separation, and the functional monomers do not displace and …
WitrynaIn this video we introduce the concept of monomers and polymers using a few examples, as well as the important reactions of condensation and hydrolysis. WitrynaWe performed molecular dynamics simulations to characterize the role of enthalpic interaction in impacting the static and dynamic properties of solvent-free polymer brushes. The intrinsic enthalpic interaction in the simulation was introduced using different attraction strengths between distinct species. Two model systems were …
