Obtenção e caracterização de filmes de amido termoplástico (TPS) adicionado de nanocelulose pela técnica casting film utilizando natural deep eutectic solvents (NADES)
(Universidade Tecnológica Federal do ParanáCampo MouraoBrasilDepartamento Acadêmico de Alimentos e Engenharia QuímicaEngenharia de AlimentosUTFPR, 2022-06-10)
Biopolymers are an alternative to polymers produced from petroleum in the packaging manufacture because they are generated from renewable sources and degrade faster. Starch has been considered very promising for the biofilms ...
Cellulose acetate membranes for osmosedimentation: Performance and morphological dependence on preparation conditions
(Elsevier B.V., 1986-06-01)
Osmosedimentation is a new membrane-assisted separation technique, based on the rapid approach to sedimentation equilibrium when macromolecular solutions are contained within dialysis cells, in contact with solvent via a ...
Mucoadhesive films based on gellan gum/pectin blends as potential platform for buccal drug delivery
(2020-02-07)
Films of gellan gum:pectin blends were prepared by solvent casting method. Gellan gum:pectin mass ratios were varied (4:1; 1:1; 1:4) at different concentrations (3% or 4%) and glycerol was used as plasticizer (1 or 2%). ...
Films from resistant starch-pectin dispersions intended for colonic drug delivery
(2014-01-01)
Free films were obtained by the solvent casting method from retrograded starch-pectin dispersions at different polymer proportions and concentrations with and without plasticizer. Film forming dispersions were characterized ...

PHBV/cellulose nanofibrils composites obtained by solution casting and electrospinning process
(2017-01-01)
In this work, nanobiocomposites of poly (3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) reinforced with cellulose nanofibrils (CNFs) were produced by electrospinning and solution casting process. CNFs were obtained by ...

Influence of the Solvent Evaporation Rate on the Crystalline Phases of Solution-Cast Poly(Vinylidene Fluoride) Films
(John Wiley & Sons Inc, 2010-04-15)
The influence of the solvent-evaporation rate on the formation of of. and P crystalline phases in solution-cast poly(vinylidene fluoride) (PVDF) films was systematically investigated. Films were crystallized from ...
