Synthesis of poly(methyl methacrylate)-b-poly(N-isopropylacrylamide) (PMMA-b-PNIPAM) amphiphilic diblock copolymer brushes on halloysite substrate via reverse ATRP

Halloysite for Controllable Loading and Release

“…Researchers have ascribed this to the highest molecular mass of the iso-butyl cyanoacrylate shell, as confirmed by gel permeation chromatography analysis [with M being approximately equal to 720,000 for poly(iso-butyl cyanoacrylate) vs 550,000 for poly-n-butyl and 570,000 for poly-octyl coatings]. Wang et al (2008) synthesised poly(methylmethacrylate)-poly (N-isopropylacrylamide) brushes on halloysite nanotubes using reverse ATRP. Urea-formaldehyde (UF) films were synthesised on halloysite surfaces by in situ polycondensation of urea and formaldehyde.…”

Development and characterization of co-loaded curcumin/triazole-halloysite systems and evaluation of their potential anticancer activity

“…Therefore, the different inner and outer-compositions of these materials allow to accomplish different chemical reactions on either surface (Massaro et al, 2014a,b;Li et al, 2008;Du et al, 2010;Wang et al, 2008;Vergaro et al, 2010;Lvov et al, 2002;Matsuno et al, 2003Matsuno et al, , 2006Ma et al, 2011Ma et al, , 2012Terayama et al, 2010;Horiuchi et al, 2009).…”

Grafting of pH-sensitive poly (N,N-dimethylaminoethyl methacrylate-co-2-hydroxyethyl methacrylate) onto HNTS via surface-initiated atom transfer radical polymerization for controllable drug release

“…Scott et al reported the grafting of random cationic copolymer brushes of DMAEMA and Nisopropylacrylamide (NIPAAm) with different monomer feed ratios on gold substrate using ATRP [31]. Up to now, various polymers are grafted onto halloysite nanotubes via "grafting from" ATRP polymerization [15,[36][37][38][39][40].…”
