PHBV/cellulose nanofibrils composites obtained by solution casting and electrospinning process

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 sulfuric acid hydrolysis from Imperata brasiliensis fibers. Nanocomposites loaded...

CNFs were obtained by sulfuric acid hydrolysis from Imperata brasiliensis fibers.

Films and mats were characterized by Scanning Electron Microscopy (SEM), X-ray diffraction (XRD) and Differential Scanning Calorimetry (DSC). It was possible to conclude that for nanobiocomposites obtained by solution casting, the addition of CNFs did not affect the transparency of the films, but provided a significant increase in the crystallization rate as observed by DSC analysis, while for electrospinning nanobiocomposites a considerable improvement in process increasing electrospinning time and quality of the mats manufactured, were observed.Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)Sao Paulo State Univ, UNESP, Dept Mat & Technol, Fatigue & Aeronaut Mat Grp, BR-12516410 Guaratingueta, SP, BrazilSao Paulo State Univ, UNESP, Dept Mat & Technol, Fatigue & Aeronaut Mat Grp, BR-12516410 Guaratingueta, SP, BrazilFAPESP: 2011/14153-8Univ Fed Rio De Janeiro, Lab HidrogenioUniversidade Estadual Paulista (Unesp)2018-11-26T17:39:54Z2018-11-26T17:39:54Z2017-01-01info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/article9application/pdfMateria-rio De Janeiro.
