Nanocellulose obtained from wood is nature’s own reinforcement material

13.04.2011

Nanocellulose is currently one of the hot research topics at Aalto University. It is made by breaking traditional cellulose fibres down into smaller and smaller fibres until they are no more than one micrometre long and 5 to 20 nanometres wide. The wood-like qualities of the cellulose disappear, and it turns into a white, even transparent, paste resembling hand cream., These properties make the products manufactured from nanocellulose light, solid and easily moulded.

The field of application for nanocellulose is extensive. In addition to the forest industry, demand for the material exists in the automotive, furniture, construction and electronics industries. Perhaps the most unexpected applications can be found in the cosmetic and pharmaceutical industries as well as in transparent OLED screens.

Nanocellulose may also have uses as a super solid structure. Aalto University is exploring the field of biomimicry, a way of producing things that emulates natural structures, such as a shell, using nanocellulose as one of its materials. The scientific study of biomaterials on the whole is expanding. In the future, are we able to replace products made of oil-based plastics with products containing nanocellulose?
