NANOFIBRILLAR CELLULOSE HYDROGEL

A nanofibrillar cellulose hydrogel is disclosed. The nanofibrillar cellulose hydrogel may comprise azido-modified nanofibrillar cellulose having a substituent represented by the formula -O-(CH2)n-S(O)m-L1-N3, wherein n is in the range of 1 to 10; m is 0 or 1; and L1 is a linker; wherein the substitu...

Beschreibung
Zusammenfassung:	A nanofibrillar cellulose hydrogel is disclosed. The nanofibrillar cellulose hydrogel may comprise azido-modified nanofibrillar cellulose having a substituent represented by the formula -O-(CH2)n-S(O)m-L1-N3, wherein n is in the range of 1 to 10; m is 0 or 1; and L1 is a linker; wherein the substituent is attached to a carbon of one or more glucosyl units of the azido-modified nanofibrillar cellulose, thus forming an ether bond to the carbon. Keksintö koskee nanofibrilliselluloosan hydrogeeliä. Nanofibrilliselluloosan hydrogeeli voi käsittää atsidomodifioitua nanofibrilliselluloosaa, jossa on substituentti, jolla on kaava -O-(CH2)nS(O)m-L1-N3, jossa n on 1 - 10; m on 0 tai 1; ja L1 on linkkeri; jossa substituentti on kiinnittynyt atsidomodifioidun nanofibrilliselluloosan yhden tai useamman glukosyyliyksikön hiileen muodostaen siten eetterisidoksen hiileen.
