What is it about?
UV-radiation, originated from sun, can be harmful for materials, plants and animals. Here we shown that chemical modified nanocellulose can be added to polymer where it works as UV-absorbent. Nanocellulose also improved the strength of polymer, making stronger material.

Why is it important?
For the first time, nanocellulose with UV-absorbing properties was produced. Nanocellulose was obtained by straightforward method, that allows the chemical modification to be performed before liberation of nanocellulose, thus eliminating cumbersome purification steps. In addition to UV-absorbing properties, addition of nanocellulose improved mechanical properties of polymer, being thus bifunctional filler material.
