  • Protocols for the chemical functionalization of hydroxypropyl cellulose using selective oxidation techniques were created and fine-tuned.
  • For the purpose of preparing hydrogels with antifreeze and conductive properties, carboxylic and/or aldehydic groups were introduced into the structure of the cellulose derivative depending on the selectivity of the oxidizing agent (TEMPO for the oxidation of primary hydroxyl groups, NaIO4 for the oxidation of secondary hydroxyl groups, TEMPO in combination with NaIO4 for the simultaneous oxidation of primary and secondary hydroxyl groups).
  • FTIR, NMR, scanning electron microscopy, and conductometric titration were the methods that were used so that the structure of the oxidized materials could be validated.
  • The "project execution plan" was successful in every way, as measured by the following indicators: 1 published work (proposal 0), participation in scientific meetings (including one oral presentation and two poster presentations), and the establishment of a website for the project.
