Nanostructuring of polymers by controlling of ionizing radiation-induced free radical polymerization, copolymerization, grafting and crosslinking by RAFT mechanism

Recent Advances and Future Trends in the Detection of Contaminants by Molecularly Imprinted Polymers in Food Samples

“…The sol-gel method is one of the most common methods for the preparation of molecularly imprinted polymers due to its intrinsic conversion efficiency and material homogeneity at the molecular level, high solvent, and thermal stability, and one-step preparation process (Beqqali et al, 2017;Guoning et al, 2020). The most common sol-gel method uses methyl orthosilicate (TMOS) or ethyl orthosilicate (TEOS) as a precursor to introduce the imprinted template into the inorganic network structure, which is homogeneously mixed in the solution state and subjected to hydrolysis and condensation chemistry to form highly stable chemically-reacted crosslinked polymers (Dai et al, 2014;Figueiredo et al, 2016;Barsbay and Güven, 2018). The three most notable features of the sol-gel method include (1) Mild operating conditions and simple preparation methods (Liu and Wulff, 2008).…”

“…It was demonstrated that The MIPs synthesized by the RAFT method presented an increase of over 100% in binding capacity at low atrazine feed concentrations compared to those prepared by conventional free-radical polymerization method where no RAFT agent was employed. Also besides, Barsbay and Güven (2018) reported the synthesis of atrazine MIPs polymers RAFT precipitation polymerization methods. The imprinting transfer efficiency of atrazine MIPs was significantly improved compared with the MIPs prepared by conventional precipitation polymerization RAFT-MIPs with spherical spatial structure and a large number of micropores on the surface.…”

Radiation-Assisted Synthesis of Polymer-Based Nanomaterials

“…This technique allows the synthesis of polymers with precise, predetermined molecular weights with very narrow dispersity. In a recent paper, nanostructuring of polymers by controlling ionizing radiation-induced free radical polymerization, copolymerization, grafting and crosslinking by the RAFT mechanism has been discussed [68]. In this section, the unique advantage of controlling of radiationinduced grafting in nanoscale is discussed considering functionalization of track-etched membranes, modification of fuel cell membranes and synthesis of polymer brushes for cell sheet harvesting.…”

Synthesis, spectral characterization and DFT calculations of novel macro MADIX agent: mechanism of addition-fragmentation reaction of xanthate compound

“…Controlled/living radical polymerization (CRP) are known as living polymerization techniques [12][13][14]. The CRP mechanisms consist of different polymerization mechanisms which are used to obtain polymers with controlled molecular weight growth and a narrow molecular weight distribution [15][16][17][18][19]. The most commonly used CRP techniques are nitroxide mediated radical polymerization (NMP) [20][21][22], atom transfer radical polymerization (ATRP) [6,23,24], reversible addition-fragmentation chain transfer (RAFT), and macromolecular design via interchange of Electronic supplementary material The online version of this article (https ://doi.org/10.1007/s4245 2-020-03495 -3) contains supplementary material, which is available to authorized users.…”
