Optically transparent membrane based on bacterial cellulose/polycaprolactone
Queiroz, P. V. S.; Borges, A. P. B.; Barud, H. S.; Ribeiro, S. J. L.; Carone, C. L. P.; Ligabue, R.; Einloft, Sandra; Jahno, V. D.Optically transparent membranes from bacterial cellulose (BC)/polycaprolactone (PCL) have been prepared by impregnation of PCL acetone solution into dried BC membranes. UV-Vis measurements showed an increase on transparency in BC/PCL membrane when compared with pristine BC. The good transparency of the BC/PCL can be related to the presence of BC nanofibers associated with deposit of PCL nano-sized spherulites w...

Role of the reactive atmosphere during the sol-gel synthesis on the enhancing o...
Freitas, Vania T.; Lima, P. P.; Ferreira, R. A. S.; Carlos, L. D.; Pecoraro, E.; Ribeiro, S. J. L.; de Zea Bermudez, V.Transparent monoliths and films of urea cross-linked tripodal siloxane-based hybrids (named tri-ureasils) were prepared by the sol-gel process, under controlled atmosphere (inside a glove box) and ambient conditions and their structure and optical features were compared. X-ray diffraction data point out that all the materials are essentially amorphous and Si-29 NMR reveal an increase in the condensation degree ...
