Estudo da reologia de hidrogéis compósitos de PEG-Laponita-alginato visando impressão 3D baseada em extrusão

Abstract: RESUMO Os hidrogéis, redes poliméricas reticuladas capazes de absorver e reter uma grande quantidade de água devido à sua natureza hidrofílica, chamam a atenção para aplicações na Engenharia Tecidual. Ainda, esses materiais oferecem o potencial de projetar arcabouços partindo do seu comportamento pseudoplástico, o que é fundamental para impressão tridimensional (3D) baseada em extrusão. A adição de Laponita, um nanosilicato bidimensional em forma de disco, permite modificar o comportamento reológico de alguns … Show more

“…[16][17][18][19][20][21][22][23][24][25][26][27][28] Mainly composed of silica (SiO 2 ), BG materials also encompass calcium (Ca), sodium (Na), and phosphorus (P) in their composition, which favor the formation of a strong bond with the host bone through a biologically active apatite layer at the material/ bone interface. Besides being used as bulk or scaffold materials, [29][30][31][32][33][34][35][36] BG has been highly explored as a reinforcing biomaterial in polymer matrices, [37][38][39][40] to improve biological and mechanical performance of the final composites. In fact, BG materials enhance bone cell activity and facilitate the ion dissolution and release, promoting a higher rate of bone formation.…”
