STRUCTURE - PROPERTY RELATIONSHIP OF CASTOR OIL BASED CHAIN EXTENDED POLYURETHANE/STARCH BIOCOMPOSITES

摘要

Polyurethane (PU)/starch biocomposites have been prepared with different weight fractions of starch (viz., from 0 to 40 wt.%). The fabricated PU/starch composites were characterized by mechanical properties and thermal (DSC and TGA) behaviors. Microcrystalline parameters were calculated using X-ray profile. Water uptake and its effect on mechanical properties have been evaluated.
