“…If the material substrate allows for radical generation, any combination of substrate and vinyl monomers would be adequate, regardless of their miscibility. In fact, radiation-induced graft polymerization accepts a wide range of materials as a modifiable substrate, including polyethylene (PE), − polypropylene, , polytetrafluoroethylene, poly(ethylene- co -tetrafluoroethylene), poly(vinylidene fluoride), poly(ether ether ketone), , and even cellulose, − to mention a few. Moreover, cellulose was reported to be an appropriate matrix for the graft polymerization of vinyl monomers such as glycidyl methacrylate, yielding cellulose-based functional fabrics .…”

Compounds derived from two major biomass components, cellulose and lignin, were artificially recombined via the radiation-induced graft polymerization of vinyl monomers, which could be potentially sourced from lignin, onto cellulose fabric. This process yielded organic hybrids featuring a cellulose substrate and surface aldehyde groups from lignin-obtained vanillin. Then, the surface Kabachnik− Fields three-component reaction (KF-3CR) of poly-(methacrylated vanillin) (PMV)-sourced aldehydes was carried out with amines and phosphites. Overall, the surface KF-3CR on the cellulose fabric grafted with PMV represents a facile preparation of multifunctional molecules on cellulose surfaces along with α-amino phosphonate ester integrations.

“…The NCG- g -PGMA nanocomposite exhibited two decomposition peaks at approximately 305 °C and 415 °C, which can be attributed to the thermal decomposition of the NCG and PGMA components of the NCG- g -PGMA nanocomposite. 56 After functionalization with C 7 F 15 COCl, the decomposition peaks of NCG and PGMA of hydrophobic NCG- g -PGMA nanocomposite slightly decreased to 276 °C and 411 °C. Since the hydrophobic NCG- g -PGMA nanocomposites did not melt or decompose up to 250 °C, they can be used at much higher temperatures than the neat polymers.…”

Here, we present the preparation of hydrophobic nanoporous cellulose gel-g-poly(glycidyl methacrylate) (NCG-g-PGMA) nanocomposites by surface-initiated atom transfer radical polymerization (SI-ATRP) of glycidyl methacrylate (GMA) monomers and hydrophobic modification with pentadecafluorooctanoyl chloride (C 7 F 15 COCl) on the cellulose nanofibrils of the NCG. The successful grafting of PGMA and hydrophobic modification of C 7 F 15 CO-groups on the NCG was evaluated by Fourier transform infrared (FTIR) spectroscopy. X-ray diffraction (XRD) and scanning electron microscopy (SEM) confirmed that the SI-ATRP and hydrophobic modification did not change the microscopic morphology and structure of the NCG-g-PGMA nanocomposites. Dynamic mechanical analysis (DMA) and thermogravimetric analysis (TGA) showed remarkable thermomechanical properties and moderate thermal stability. The method has tremendous promise to use NCG as a platform for SI-ATRP and produce new functional NCG-based nanomaterials.

“…As shown in Fig. 2(a), the three peak were represent as volatilization of physically adsorbed water, pyrolysis of the grafted GMA and MCC, and the grafted phosphorus-containing t-DOPO, respectively (Misra et al 2016). t-DOPOR exhibited higher char yields (22.77%) than MCC and MCC-g-GMA at 800 °C due to the introduction to phosphorus-containing groups of t-DOPO.…”

Effective radioactive wastewater disposal is of great significance to the wide use of nuclear energy. In this work, 4, 4ˊ-[1, 4-phenyl-bis (9, 10-dihydro-9-oxa-10-phosphaphenanthrene-10-yl) dimethyneimino)] diphenol (t-DOPO) was used to modify microcrystalline cellulose microsphere (t-DOPOR) to further enhance it affinity toward U(VI) through radiation method. The t-DOPOR were characterized for structural, morphological, and thermal properties by FTIR, SEM and TGA, which prove that t-DOPO is successfully modified on cellulose. Combination the advantage of cellulose and t-DOPO, t-DOPOR possessed abundant functional group (-OH, -NH and P=O), and exhibited extremely strong affinity toward U(VI) with a maximum adsorption capacity of 51.51 mg/g at pH 3. Particularly, A large distribution, KdU, up to 2.54×104 mL g−1 is found, implying extremely strong affinity toward U(VI) than Ln(III) (La(III), Eu(III), Dy(III), Yb(III)) at the binary system. Dynamic column experiment confirmed that t-DOPOR could separate selectively U(VI) in column experiment. In addition, even in the simulated groundwater trace amount of U(VI) was also eliminated efficiently by t-DOPOR. Lastly, the adsorption mechanism elaborated by XPS analysis was inner-sphere surface complexation between U(VI) and -OH, -NH and P=O groups of t-DOPOR. Overall, the synthesized t-DOPOR may be utilized as a promising adsorbent for separation and remediation of U(VI) from wastewater.
