Modificação da molhabilidade da celulose por processos subsequentes de ablação e deposição a plasma
(Universidade Federal de São Carlos, 2017-03-14)
Cellulose is a biopolymer available in abundance in nature, which presents very interesting properties mainly for the textile, packaging and paper industry. However, due to its strongly hydrophilic character, resulting ...
Tratamento a plasma de nanofibrilas de celulose para aplicação em compósitos
(Universidade Federal de São Carlos, 2017-03-15)
The application of cellulose nanofibrils to the production of composites has been studied and presents promising results, mainly due to the abundance of the material, which is of a renewable source, and to its low cost. ...
Obtenção de nanocelulose a partir da funcionalização da celulose por oxipropilação
(Universidade Federal de São Carlos, 2020-03-27)
The present study aimed to obtain functionalized nanocellulose through the oxypropylation reaction. Thereunto, the cellulose was submitted to an initial activation step with a sodium hydroxide solution, and then the reaction ...
Síntese e caracterização de géis para cromatografia de exclusão por tamanho via reticulação de Acetato de Celulose com 4,4' - Difenilmetano Diisocianato (MDI)
(Universidade Federal de São Carlos, 2016-03-28)
The need to obtain biomaterials in order to reduce environmental impacts has been the focus of research groups in recent years, and cellulose, a dominant component at most forms of plants is a promising resource because ...
Nanocristais de celulose provenientes de fibras amazônicas com potencial aplicação na produção de nanocompósitos
(Universidade Federal de São Carlos, 2021-11-19)
Among all the natural polymers, we can highlight the use of cellulose, a mutable and profuse biopolymer in nature, which has enormous chemical variability due to the functionalization of its various hydroxyl groups. It can ...
Obtenção de nanocelulose via hidrólise ácida a partir dos resíduos da produção de cerveja
(Universidade Federal de São Carlos, 2016-04-01)
The industrial waste usage for technological application has been gaining ground in different segments and applications. One of the prominent sectors is Material technology, where these residues can be used to obtain the ...
