Preparation and characterization O-lauroyl chitosan/poly (L-lactic acid) blend membranes by solution-casting approach

Received Date: 5 June 2006

Fund Project: This work was supported by the National Natural Science Foundation of China (nos. 20274013 and 20574024),the Key Project of the Fujian Provincial Science and Technology (no. 2002I004),and the Fujian Provincial Natural Science Foundation (no. E0540001).

O-Lauroyl chitosan/poly(L-lactide) (OCS/PLLA) blend membranes with different compositions were prepared by solutioncasting approach using chloroform as common solvent. The experimental results of FT-IR, DSC and WAXD indicated that interassociation hydrogen-bond interactions existed between OCS and PLLA in the blend membranes. And SEM observation confirmed that the blend membranes with suitable compositions were compatible.
