Definitions

  • the method according to the invention further comprises, subsequent to the irradiation step (ii) with microwaves, an elimination step (iii), for example by dialysis against water , ethanol or tetrahydroiuran (THF), residual organic chromophore molecules, not attached to nanocellulose.
  • an elimination step for example by dialysis against water , ethanol or tetrahydroiuran (THF), residual organic chromophore molecules, not attached to nanocellulose.
  • the present invention relates to a semi-crystalline nano and / or micro-fribrile cellulose labeled with at least one chromophoric organic molecule, obtained according to the method of the invention defined above.
  • it also relates to the use of marked nano and / or micro-crystalline semicrystalline cellulose, obtained according to the method of the invention, for coating substrates such as films, in particular of a nature cellulose.
  • the chromophores used according to the invention may be more particularly chosen from:
  • IR-140 (5,5'-Dichloro-11-diphenylamino-3,3'-diethyl-10,12-ethylenethiatricarbocyanine perchlorate, CAS No. 53655-17-7)
  • Rhodamine 6G perchlorate (9- [2- (ethoxycarbonyl) phenyl] -3,6-bis (ethylamino) -2,7-dimethylxanthylium perchlorate, CAS No. 13161-28-9)
  • the fluorescent chromophore according to the invention is chosen from compounds of white color in visible light, such as derivatives of pyrene or dansylcadaverine.
  • the aqueous chromophore solution is then added with vigorous stirring to the nanocellulose suspension.
  • a sample of nanocellulose is treated with TMPyP, as described in Example 1 above, but omitting the microwave irradiation step. At the end of the dialysis purification step, the fluorescence of the nanocellulose is not observed.
