Journal ArticleDOI
Superabsorbent hydrogel composite made of cellulose nanofibrils and chitosan-graft-poly(acrylic acid)
Cristiane Spagnol,Francisco H. A. Rodrigues,Antonio G.B. Pereira,André R. Fajardo,Adley F. Rubira,Edvani C. Muniz +5 more
TL;DR: In this paper, a 24−1 fractional factorial design was employed to evaluate the effect of acrylic acid/chitosan molar ratio, crosslinker, initiator, and filler in the swelling capacity of hydrogel composites.
Journal ArticleDOI
Superabsorbent hydrogel nanocomposites based on starch- g -poly(sodium acrylate) matrix filled with cellulose nanowhiskers
Cristiane Spagnol,Francisco H. A. Rodrigues,Antonio G.B. Pereira,André R. Fajardo,Adley F. Rubira,Edvani C. Muniz +5 more
TL;DR: In this article, a set of experiments were performed to evaluate the influence of some factors such as NaAc/starch mass ratio, crosslinker, and nanowhiskers amount in the swelling capacity and swelling kinetics.
Journal ArticleDOI
Nanocomposites based on poly(acrylamide-co-acrylate) and cellulose nanowhiskers
Cristiane Spagnol,Francisco H. A. Rodrigues,Francisco H. A. Rodrigues,Alberto Gonçalves Vieira de Carvalho Neto,Antonio G.B. Pereira,André R. Fajardo,Eduardo Radovanovic,Adley F. Rubira,Edvani C. Muniz +8 more
TL;DR: In this paper, a series of hydrogels were synthesized varying the percentage of CNWs (1, 2, 5, 10, and 20 ) and the amount of crosslinking agent (0.05, 0.15, and 0.20 ).
Journal ArticleDOI
Superabsorbent hydrogel composites with a focus on hydrogels containing nanofibers or nanowhiskers of cellulose and chitin
Francisco H. A. Rodrigues,Cristiane Spagnol,Antonio G.B. Pereira,Alessandro F. Martins,André R. Fajardo,Adley F. Rubira,Edvani C. Muniz +6 more
TL;DR: In this paper, the authors discuss relevant aspects of the current knowledge of superabsorbent hydrogels and nanocomposite polymer hyrogels, mainly those based on chitin and cellulose nanocrystals (fibers and/or whiskers), bringing to light some structure-property relationships and future trends.
Journal ArticleDOI
Mechanically improved polyvinyl alcohol-composite films using modified cellulose nanowhiskers as nano-reinforcement.
Cristiane Spagnol,Elizângela H. Fragal,Maria A. Witt,Heveline D.M. Follmann,Rafael Silva,Adley F. Rubira +5 more
TL;DR: A significant increase in mechanical properties such as tensile strength, elastic modulus, and elongation at break showed a close relationship to the amount and chemical surface characteristics of CWs added, suggesting that these modified-CWs could be explored as reinforcement additives in PVA films.
