Ternary nano-biocomposite films based on poly(lactic acid) (PLA) with modified cellulose nanocrystals (s-CNC) and synthesized silver nanoparticles (Ag) have been prepared and characterized. The functionalization of the CNC surface with an acid phosphate ester of ethoxylated nonylphenol favoured its dispersion in the PLA matrix. The positive effects of the addition of cellulose and silver on the...

Biological systems such as proteins, viruses, and DNA have been most often reported to be used as templates for the synthesis of functional nanomaterials, but the properties of widely available biopolymers, such as cellulose, have been much less exploited for this purpose. Here, we report for the first time that cellulose nanocrystals (CNC) have the capacity to assist in the synthesis of metall...

Ultrathin films of aligned cellulose nanocrystals (CNCs) were assembled on mica supports by using electric field-assisted shear. The relationship between polarization gradients and strain mechanics of the obtained films was examined by monitoring their deflection with an atomic force microscope operated in contact mode. The piezoelectric response of the films was ascribed to the collective cont...

We study composites of cellulose nanocrystals (CNCs) in an ionomer matrix poly(ethylene-stat-sodium acrylate) and find that direct cellulose/cellulose interactions the composite are not a requirement for achieving reinforcement. While isotropic only show slightly enhanced stiffness compared to neat ionomer, more substantial increase Young’s modulus by factor up 5 is achieved uniaxial alignment ...

We report physical adsorption of highly anisotropic copolymer worms with either anionic or cationic charge onto planar silica, cellulose nanocrystal nanofibril surfaces using a quartz crystal microbalance dissipation monitoring.

The transition to low-carbon emitting technologies provokes an increasing demand in energy conversion and storage systems such as fuel cells, batteries, supercapacitors, consequently, the need for their raw materials. use of new chemistries from earth-abundant precursors instead scarce, toxic, nondegradable components existing current must be a priority future years. Cellulose is most abundant ...
