Grafting of porphyrins on cellulose nanometric films.
Ultrathin films of cellulose were functionalized with iron protoporphyrin IX (FePP). Spin-coating allows the production of silylated cellulose films in a controlled way. Cellulose regeneration is achieved through the hydrolyzation of the silane groups, exposing the film to acidic vapors. To enhance the reactivity of the cellulose surface to the protoporphyrin, carbonyldiimidazole (CDI) was used...
متن کاملAll-Cellulose Composite Fibers Obtained by Electrospinning Dispersions of Cellulose Acetate and Cellulose Nanocrystals
All-cellulose composite fibers were produced by electrospinning dispersions containing cellulose acetate (CA) and cellulose nanocrystals (CNCs). Precursor polymer matrices were obtained after dispersion of CA with different degrees of substitution in a binary mixture of organic solvents. The obtained fibers of CA loaded with CNCs had typical widths in the nanoand micro-scale and presented a gla...
متن کاملAntibacterial Modification of Microcrystalline Cellulose by Grafting Copolymerization
Microcrystalline cellulose (MCC) has the advantage of a high specific surface area as compared to that of conventional cellulose fibers. In this study the monomer methacrylamide (MAM) was used to treat MCC by grafting copolymerization. SEM, FTIR, and solid C NMR were used to characterize the morphology and composition of MAM-g-MCC. After the chlorination of MAM-g-MCC with 10% sodium hypochlorit...
متن کاملCellulose solvent-based biomass pretreatment breaks highly ordered hydrogen bonds in cellulose fibers of switchgrass.
The switchgrass (SG) samples pretreated by cellulose solvent- and organic solvent-based lignocellulose fractionation were characterized by enzymatic hydrolysis, substrate accessibility assay, scanning electron microscopy, X-ray diffraction (XRD), cross polarization/magic angle spinning (CP/MAS) (13)C nuclear magnetic resonance (NMR), and Fourier transform infrared spectroscopy (FTIR). Glucan di...
متن کاملAcrylates.
ACRYLATES HAVE been around since the 1930s, when Rohm and Haas began mass production of Plexiglas, a clear and resistant glass substitute made of polymerized methacrylate. It is used extensively for windowpanes, airplane canopies, car lights and windshields, streetlamps, and so on. Numerous other acrylates have been synthesized and have found applications in paints and adhesives, dental composi...
