“…The peaks at around 1,650 and 1,065 cm -1 can be attributed to O-H bending of absorbed water (Lu and Hsieh 2010) and C-O-C stretching of pyranose and glucose ring skeletal vibration (Cherian et al 2008), respectively. Compared with CNCs, a new peak at 436 cm -1 , assigned to Zn-O stretching vibration, was distinctly observed, confirming the nanocrystalline character of the resulting ZnO nanoparticles in the nanohybrids (Azizi et al 2013;Zhang et al 2013). With increasing concentration of Zn 2?…”

“…However, the CNC/ZnO nanohybrids showed a new characteristic absorption peak at 356-367 nm, which could be ascribed to the basic bandgap absorption of ZnO because of electron transitions from the valence to conduction band (O 2p ? Zn 3d) (Zak et al 2011;Zhang et al 2013). This confirms the formation of ZnO nanoparticles on the surface of the CNCs.…”

“…The antibacterial activity of the nanohybrids against S. aureus and E. coli was studied using the qualitative agar disc diffusion method and quantitative mean colony-forming units method as reported in previous literature (Azizi et al 2013;Yu et al 2014;Zhang et al 2013). In the agar disc diffusion method, the antibacterial activity of the CNC/ZnO nanohybrids and CNCs was measured on solid-agar Petri dishes with CNCs used as control.…”

“…Zinc oxide (ZnO) nanoparticles are multifunctional inorganic metal oxides that have recently attracted considerable interest due to their extensive applications as photocatalysts and antibacterial materials, as well as in sensors and dye-sensitized solar cells (Fallah et al 2011;Roberson et al 2014;Velmurugan and Swaminathan 2011;Zhang et al 2013;Zheng et al 2014). However, ZnO nanoparticles tend to aggregate due to their large surface area and high surface energy (Azizi et al 2013;Li et al 2013).…”

Cellulose nanocrystal/zinc oxide (CNC/ ZnO) nanohybrids were prepared through citric hydrochloric acid hydrolysis of commercial microcrystalline cellulose (MCC), and simple precipitation with zinc nitrate aqueous solution [Zn(NO 3 ) 2 Á6H 2 O] via one-pot green synthesis, in which preparation and modification of CNCs were performed simultaneously and the obtained CNCs with carboxyl groups could act as a stabilizing and supporting agent to anchor ZnO nanoparticles. The influence of the Zn 2? ion concentration on the morphology, microstructure, and properties of the CNC/ZnO nanohybrids was investigated by using Fourier-transform infrared and ultravioletvisible (UV-Vis) spectroscopy, X-ray diffraction (XRD) analysis, field-emission scanning electron microscopy, and thermogravimetric analysis. According to the UV-Vis and XRD results, well-dispersed ZnO nanoparticles with hexagonal wurtzite structure and smallest average diameter of 42.6 nm were successfully anchored onto the surface of the CNCs. The CNC/ ZnO nanohybrid CNC/ZnO-0.5 showed improved thermal stability, high antibacterial activity, and photocatalytic activity for methylene blue (MB) due to strong interaction between the CNCs and ZnO nanoparticles. Compared to CNCs, the thermal degradation onset temperature (T 0 ) of the nanohybrids was increased by 23.9°C, while antibacterial ratios of 100.0 and 100.0 % against viable Escherichia coli and Staphylococcus aureus were achieved. Moreover, 93 % of MB dye was decomposed after UV light irradiation for 100 min.

Transparent nanocellulose hybrid films functionalized with ZnO nanostructures for UV-blocking

et al. 2015

Transparent, nanocellulose-ZnO (NC-ZnO) hybrid films were fabricated via a pressure controlled extrusion process using NC fibrils and sheet-like ZnO (s-ZnO) or belt-like ZnO (b-ZnO) nanostructures. The s-ZnO and b-ZnO conjoined with the NC fibrils to form a heterogeneous, fibrous network structure. The NC-ZnO hybrid films with different amounts of ZnO nanostructures showed a synergic feature of high optical transparency and excellent UV-blocking. The results indicated that NC assembled with s-ZnO hybrid film possessed excellent UV-blocking ability in a wide range from 200 to 375 nm, in contrast to NC-b-ZnO.Moreover, the prominent thermal and photo stability of transparent NC-ZnO hybrid films enhanced extensibility and ease of use for diverse biological applications, which require tolerance of temperature changes.
