PH and thermo dual-sensitive copolymers with fluorescent properties grafted mesoporous silica SBA-15 via metal-free ATRP

Polymer-modified regenerated cellulose membranes: following the atom transfer radical polymerization concepts consistent with the principles of green chemistry

“…Low catalyst loading methods offer more environmentally benign and industrially scalable reaction conditions compared to "classical" ATRP but also provide an option to prepare polymers with designed dispersity, defined by the catalyst content (Discekici et al 2018(Discekici et al , 2016(Discekici et al , 2017Lu et al 2019;Matyjaszewski 2012a;Parkatzidis et al 2020;Treat et al 2014). The new low ppm ATRP methods regenerate the activator by the use of a chemical reducing agent as a radical initiator in initiators for continuous activator regeneration (ICAR) ATRP (Konkolewicz et al 2012;Luan et al 2022), chemical compounds (Luo et al 2022;Matyjaszewski et al 2007;Min et al 2007) and silver (Williams et al 2015) in activators regenerated by electron transfer (ARGET) ATRP-used a few times for membrane modification (Bhut et al 2012;Worthley et al 2011), zerovalent metals in supplemental activator and reducing agent (SARA) ATRP (Chmielarz et al 2015a;Konkolewicz et al 2014Konkolewicz et al , 2013, external stimuli as an electrical current in electrochemically mediated ATRP (eATRP) (Chmielarz 2017;Chmielarz et al 2015b;De Bon et al 2022;Han et al 2022;Park et al 2015;Zhao et al 2022), light in metal-free (Soly et al 2022;Su et al 2022;Treat et al 2014) or photochemically mediated ATRP (photo-ATRP) (Fu et al 2021;Huang et al 2017;Tasdelen et al 2011), mechanical forces in mechanically induced ATRP (mechano-ATRP) (Liu et al 2022a;Mohapatra et al 2018;Wang et al 2019), ultrasound in ultrasonication-induced atom tran...…”
