“…In addition to inorganic materials such as silicon, metal, and carbon allotrope, organic polymer particles, films, and fibers can be now modified by surface-initiated living radical polymerization with a copper catalyst toward creation of novel surface-functionalized materials. The substrates are extended to wide variety of polymeric compounds, as shown in the following examples: (1) organic polymer particles polydivinylbenzene, divinylbenzene cross-linked polystyrene latex, polystyrene latex, Wang resin, Merrifield resin, and chitosan; (2) films nylon, poly(ethylene terephthalate), polyimide, polytetrafluoroethylene, poly(vinylidene fluoride), poly(vinyl chloride), and isotactic polypropylene; (3) fibers cellulose of filter paper. , Conveniently, the poly(vinylidene fluoride) and poly(vinyl chloride) films can directly initiate copper-catalyzed living radical polymerization without any extra introduction of initiating moieties. Thanks to the versatility of applicable monomers and solid surface substrates, metal-catalyzed system tremendously contributes new vistas to synthesis of surface-modified materials with unique functions.…”

“…In this current work, PVC- co -CPVC fiber is used as a backbone to graft AN and t BA via ATRP copolymerization for the preparation of uranium adsorbent fibers. Previous works on ATRP from a similar backbone polymer (PVC) included the grafting of various monomers (e.g., AN), , hydroethyl acrylate, butyl acrylate, , 2-ethylhexylacrylate, , methyl methacrylate, , tert -butyl methacrylate, glycidyl methacrylate, poly(oxyethylene methacrylate), − acrylamide, N -vinylpyrrolidone, 4-vinylpyridine, styrene, and styrene sulfonic acid . All the PVC, partially dehydrochlorinated PVC, or poly(vinyl chloride- co -vinyl acetate) polymers used in the aforementioned study were in the form of powders, beads, films, sheets, or suspensions, but not fibers.…”

The need to secure future supplies of energy attracts researchers in several countries to a vast resource of nuclear energy fuel: uranium in seawater (estimated at 4.5 billion tons in seawater). In this study, we developed effective adsorbent fibers for the recovery of uranium from seawater via atom-transfer radical polymerization (ATRP) from a poly(vinyl chloride)-co-chlorinated poly(vinyl chloride) (PVC-co-CPVC) fiber. ATRP was employed in the surface graft polymerization of acrylonitrile (AN) and tert-butyl acrylate (tBA), precursors for uranium-interacting functional groups, from PVC-co-CPVC fiber. The [tBA]/[AN] was systematically varied to identify the optimal ratio between hydrophilic groups (from tBA) and uranyl-binding ligands (from AN). The best performing adsorbent fiber, the one with the optimal [tBA]/[AN] ratio and a high degree of grafting (1390%), demonstrated uranium adsorption capacities that are significantly greater than those of the Japan Atomic Energy Agency (JAEA) reference fiber in natural seawater tests (2.42–3.24 g/kg in 42 days of seawater exposure and 5.22 g/kg in 49 days of seawater exposure, versus 1.66 g/kg in 42 days of seawater exposure and 1.71 g/kg in 49 days of seawater exposure for JAEA). Adsorption of other metal ions from seawater and their corresponding kinetics were also studied. The grafting of alternative monomers for the recovery of uranium from seawater is now under development by this versatile technique of ATRP.

The research presented details chemical modifications of poly(vinyl chloride) (PVC) and its derivative, dehydrochlorinated PVC (DH-PVC) through the use of two grafting techniques, namely a normal fullerenation, using AIBN (2,2 0 -Azoisobutyronitrile), and the atom transfer radical addition (ATRA). The products were characterized and the presence of new FTIR peaks at 528 and 577 cm 21 along with new 1 H-NMR signal at 3.9 ppm, suggested that fullerenes has been grafted to the polymer molecules. Percentage of C 60 in the fullerene grated products determined by UV/Visible spectroscopy initially increased with the amount of fullerene used to a maximum value (5.66 % wt) before decreasing again. It was also determined that the C 60 content of the fullerene grafted PVC product prepared by using ATRA, was notably greater than that obtained using the normal fullerenation approach, regardless of the amount of C 60 used. When the dehydrochlorinated PVC was used as the starting polymer for fullerenation, the fullerene grafted DH-PVC using ATRA, was markedly insoluble in many common solvents (THF and dichlorobenzene). This was not the cases for the fullerene grafted DHPVC prepared via an AIBN based fullerenation. Furthermore, the electrical conductivity values of the modified PVC products determined by using a four-point probe method were found to increase linearly with the amount of C 60 present. Overall our data suggest that the suitable and efficient techniques for grafting C 60 onto PVC and DHPVC chains are ATRA and AIBN-based fullerenation, respectively.
