What are the properties of nanocellulose?

Nanocellulose has the desirable properties of cellulose such as biodegradability, low density and non-toxicity; along with certain special properties such as great mechanical and thermal stability, self-assembly in aqueous dispersion media, reinforcing capabilities and long-lasting nature (Thomas et al., 2018).

Is graphene resistant to heat?

Graphene is considered an excellent heat conductor, and several studies have found it to have unlimited potential for heat conduction based on the size of the sample, contradicting the law of thermal conduction (Fourier’s law) in the micrometer scale.

What can nanocellulose be used for?

Nanocellulose can be used in tampons, sanitary napkins or wound dressing in the form of freeze-dried nanocellulose aerogels. Intestinal disorders can be treated by tablets comprising dry solid nanocellulose. Nanocellulose can be used as a composite coating agent in cosmetics for nails, hair, eyebrows or eyelashes.

What makes graphene a good thermal conductor?

Graphene is a two-dimensional (2D) material with over 100-fold anisotropy of heat flow between the in-plane and out-of-plane directions. High in-plane thermal conductivity is due to covalent sp2 bonding between carbon atoms, whereas out-of-plane heat flow is limited by weak van der Waals coupling.

Is graphene a thermal insulator?

A graphene aerogel has outstanding performance as an electrical conductor and insulator but it is not limited to optimizing electronics. Its remarkable thermal and sound insulation properties, ultra-high porosity, and inherent flame retardation mean that it could have a wider variety of applications.

Is graphene cold resistant?

Graphene-based foam stays soft and squishy even at super cold temperatures.

Why is nanocellulose so strong?

The strong hydrogen bonding among the neighboring fiber cells enables the effective utilization of the ultra-strength of nanocellulose.
