  Abstract

Nanocrystalline cellulose (NCC), as a kind of robust renewable green nanomaterials, can be used as an emulsion stabilizer and a reinforcing fi ller for coatings. However, the high polarity of NCC limits its interfacial interaction and dispersion with non-polar polymers. This work presented an environmentally friendly and simple strategy to generate star-shaped nanocrystalline cellulose/fl uorinated polyacrylate with outstanding water뱋il repellent properties and mechanical property via RAFT-mediated emulsion polymerization using poly(acrylic acid)- b -poly(hexafl uorobutyl acrylate)- g -nanocrystalline cellulose particles as stabilizers. The infl uences of the HFBA content and pH value on emulsion polymerization and nanocomposite fi lm properties were systematically studied. The infl uences of the HFBA content and pH value on the emulsion polymerization process and the surface properties of the latex fi lms were discussed. The results showed that the nanocrystalline cellulose/fl uorinated polyacrylate emulsion with good stability was prepared under the condition that when the pH value was 9.26, HFBA content was 10 wt%, and the water contact angle and oil contact angle of the nanocomposite fi lm were 110.8째 and 95째, respectively. The chemical structure of star-shaped nanocrystalline cellulose/fl uorinated polyacrylate was confi rmed by 1 H-NMR and FT-IR spectroscopy, respectively. The thermal stability of the latex fi lm was raised remarkably with the increase of HFBA content. AFM measurement results indicated that nanocrystalline cellulose particles could improve the roughness of the nanocomposite fi lm. And the roughness of the nanocomposite fi lm increased with the increase of the content of PAA- b -PHFBA- g -NCC particles. The results showed that the fi nished fabric had excellent softness, washing resistance, water and oil resistance.
