Thermoresponsive poly(poly(ethylene glycol) methylacrylate)s grafted cellulose nanocrystals through SI-ATRP polymerization

Thermally Switchable Liquid Crystals Based on Cellulose Nanocrystals with Patchy Polymer Grafts

“…Furthermore, the temperature range for the response can be adjusted based on the monomer(s) chosen in the polymerization. For example, the liquid crystal switch could be tailored within 25–90 °C by using this reaction scheme to graft poly(ethylene glycol) methacrylates with varying ethylene glycol side chain lengths . Effects of the grafted polymer molecular weight and concentration of particles on the temperature response of the liquid crystal are likely to be fruitful subjects for future studies.…”

“…A widely used approach to impart nanoparticles with temperature‐dependent properties is their surface functionalization with a thermoresponsive polymer . The grafting of several thermoresponsive polymers from CNC surfaces has been previously achieved via controlled radical polymerization routes after reacting surface hydroxyl groups with suitable initiators, which afforded uniformly decorated “brush”‐like modified CNCs . In aqueous suspensions, such “hairy” nanoparticles exhibited thermo‐reversible aggregation and gelation above the lower critical solution temperature (LCST) of the grafted polymer, resulting in a four‐ to sixfold increase of the hydrodynamic diameter and a corresponding increase of the dynamic storage modulus .…”

Thermoresponsive 2-hydroxy-3-isopropoxypropyl hydroxyethyl cellulose with tunable LCST for drug delivery

“…25,26 For example, the LCST values of cellulosebased thermoresponsive polymers, i.e., nanocrystals-g-poly(poly(ethylene glycol) methylacrylate)s, cellulose-g-poly(N,N-diethylacrylamide), and hydroxypropyl cellulose-g-PNIPAM are 34-66, 18-26, and 28-42 C, respectively. [27][28][29] These graed copolymers combine the virtues of the thermal responsiveness of synthetic polymers and the biocompatibility of cellulose and its derivatives. In recent years, increasing number of publications have demonstrated that self-assembly as a feasible and effective strategy to prepare cellulose-based thermoresponsive materials has been deeply studied.…”

Bamboo Flour/Petg Composites: Compatibilizing Effect of Poly(methyl Methacrylate) Grafted Onto Bamboo Flour

“…Based on that, the modification of cellulose or wood flour by graft copolymerization provides a significant route to increase dispersion of the particles, reduce water sorption, or improve composite properties. Over the past two decades, many techniques, such as free radical polymerization, [16][17][18][19][20] ring-opening polymerization, 21,22 single-electron-transfer living radical polymerization (SET-LRP), 23,24 nitroxide-mediated polymerization (NMP), 25,26 reversible addition-fragmentation chain transfer (RAFT) polymerization 27,28 and atom transfer radical polymerization (ATRP), [29][30][31][32][33][34] have been applied to cellulose grafting. Among these techniques, ATRP, proposed by Matyjaszewski 35 and Sawamoto, 36 is one of the most powerful and versatile techniques.…”
