Endurance of linear and cross-linked shape memory polyurethane under rigorous hydrolysis conditions
Source abstract
Abstract
Linear shape memory polyurethane (SMPU) copolymers synthesized from 4,4′-methylene bis(phenylisocyanate) (MDI), poly(tetramethyleneglycol) (PTMG), and 1,4-butanediol (BD), and cross-linked SMPU by glycerol were being tested under the severe hydrolysis conditions for the tensile mechanical properties and the shape memory effect for 6 months. Tensile mechanical properties and shape memory effect were not substantially decreased after 6 months of storage, and SMPU structure was not affected during the long-term hydrolysis test as evidenced by IR, DSC, contact angle, and viscosity. Hydrolysis test was important in proving the durability of SMPU before application of SMPU in aqueous surrounding.
