Cellulose is the most naturally occurring biomolecular polymers ensemble into cellulose nanofibers that has both amorphous and crystalline domains in proportions dependent on the source. Cellulose nanofibrils have raised significant interest as excellent structural materials with exceptional mechanical properties. It is important to understand the structure of CNF and its synergy. This study entails molecular dynamics simulations of the cellulose nanofibrils to give insightful understanding of its atomic details in response to temperature. GROningen Machine for Chemical Simulations (GROMACS) is used as the simulations software and All-Atom Optimized Potential for Liquid Simulations (OPLS-AA) force field is chosen for the simulation. To understand the thermally induced structural changes, lattice parameters, crystal density, hydrogen bonding network and other parameters are critically analyzed. The total number of hydrogen bonds is also observed.
The appeal of portable electronic devices is growing gradually, which increases the demand for flexible and renewable energy storage devices. Hybrid materials can be used as renewable and flexible electrode material for this kind of devices. Organic–inorganic hybrid materials represent a creative substitute to design new materials and composites by accepting advantages of both materials. This paper reports the possibility of renewable cellulose and graphene composite as an electrode material for energy storage device such as supercapacitor. The morphology and structure of the nanocomposite are studied using scanning electron microscope and Energy-dispersive X-ray Spectroscopy. The performance of the composite as supercapacitor electrode material is evaluated by cyclic voltammograms and galvanostatic charge-discharge curves.
Hybrid composites with organic and inorganic materials are drawing interest to researchers by adopting advantages of
organic materials and inorganic materials. Cellulose is biocompatible, cheap, environmentally friendly, renewable and
lightweight material. Nano crystalline form of cellulose (CNC) is a needle like rigid structure with a very high mechanical
strength. Graphene, crystalline forms of carbon, provides basic platform for many electronic and optoelectronic devices.
This paper introduces the fabrication process of cellulose nanocrystal/graphene oxide blended nanocomposite film.
Cellulose nanocrystal/graphene oxide nanocomposite films are prepared by mixing graphene oxide (GO) into cellulose
nanocrystal suspension using ultrasonic homogenizer. Scanning electron microscopy is used to study morphology. Optical
properties of the composite was characterized to evaluate the change in transparency after addition of GO in CNC.
