Low Fluorinated Oligoamides for Use as Wood Protective Coating

New highly hydrophobic fluorinated oligoamides were synthesized and studied as materials for the protection of non-varnishable wooden artifacts. The new designed to achieve best performance (including high chemical affinity wood material) lowest environmental impact. In order minimize risk bioaccumulation, short perfluoroalkyl side chains reacted with oligoethylene L-tartaramide (ET), adipamide-L-tartaramide (ETA), succinamide-L-tartaramide (EST), succinamide (ES), oligodiethylenetriamino-L-tartaramide (DT). Favorable reaction conditions also adopted obtain low molecular weight compounds characterized by non-film-forming properties solubility or dispersibility in environmentally friendly organic solvents. Their behavior terms modification surface characteristics, such wettability, moisture absorption, color, was analyzed using a specific diagnostic protocol rapidly preliminary, but reliable, results optimizing future synthesis tailored protectives. influence different monomer units on reactivity, solubility, compared showing ESF (contact angle 138.2°) DF (132.2°) most effective products. study stability photochemical degradation confirms promising protective agents artefacts historical artistic interest place long-chain substances (PFAS), products currently subject restrictions use.
