These were compared to membranes of commercial cellulose acetate (Rhodia). All produced membranes were asymmetric, characterized by the presence of a dense skin and a porous support. Differences regarding the morphology of the surfaces as well as of the porous support can be noticed. Scanning Electron Microscopy (SEM)showed that the morphology of the superficial layer, responsible for transport, depends on the different lignin content of the starting material and also on the viscosity average molecular weight of the cellulose acetates produced from sugar- cane bagasse, mango seed, and Rhodia’s commercial cellulose acetate.Submitted by Ana Valéria de Jesus Moura (anavaleria_131@hotmail.com) on 2012-03-06T20:13:27Z No. of bitstreams: 1 SEM study of the morphology of asymmetric cellulose.pdf: 173937 bytes, checksum: d76e333db281047599918fd71c63d035 (MD5)Made available in DSpace on 2012-03-06T20:13:27Z (GMT).
