Compósitos ppticamente transparentes baseados em celulose bacteriana e boehmita, siloxano e/ou sistema boehmita-siloxano

The present invention comprises composites with multifunctional characteristics, being capable of substituting glass, with significant advantages, with particular emphasis on flexibility, for a variety of applications such as, for example, display screens and others. Among other aspects, the product that constitutes the object of the invention is particularly characterized by rendering bacterial cellulose transparent, in addition to being flexible, biocompatible and able to replace glass in 100% of possible applications. Among other aspects, the development of the composites according to the present invention allows an effective increase in optical transmission, enabling an optical transmission of more than 90%, such transparency being necessary, equally, for the development of medical devices, for example.

Método de utilização de membrana de celulose bacteriana intra articular sobre superfície lesada de patela

The present invention discloses the use of the bacterial cellulose membrane in ligament, tendon and synovial capsule reconstructions according to the methods described in the technical description of the invention. Said material could be used in the reconstruction of ligaments and tendons (the knee cruciate ligaments, patellar ligament, Achilles tendon, quadriceps tendon, etc.) and the synovial capsule.

Nanocompósitos multifuncionas de fibroína reforçados com biocelulose

This work shows the preparation and characterization of the new nanocomposites based on fibroin and biocellulose. Bacterial cellulose (BC) is an exopolysaccharide produced by bacteria of the genus Gluconacetobacter, which it has identical chemical structure of the cellulose from plants and it has gained attention in the field of research for its unique properties as excellent mechanical properties when dry and hydrated , higher capacity of water retention, moldability , biodegradability and excellent biological affinity . Silk fibroin (SF) is a structural protein present in the cocoon of the silkworm, Bombyx mori, has been identified as suitable for developing optical devices, tissue engineering application, enzyme immobilization, controlled release drug agent biopolymer. Silk fibroin/bacterial cellulose nanocomposite films were prepared impregnating different cellulose charges (0.5 %, 1.0 %, 1.5 %, 2.5 %, 5.0 % and 10.0 %) weight/weight. According mechanical tests and water and Paynes's cup permeability showed that SF/BC 1% nanocomposite has the most relevant results. Poliethylenoglicol (PEG) containing SF films improved optical and mechanical properties when compared to pristine SF film. New SF/BC nanocomposites could be applied in Medicine, as biodegradable packaging and flexible substrates for OLEDs.
