Synthesis and characterization of air-cure polyurethane bioadhesives basedon PEG and PCL

Polyurethanes are a good candidate to use instead of sutures in wound closer applications. In thisstudy air-cure polyurethane bioadhesives were synthesized by pre-polymerization methods based onPolyethylene glycol (PEG) and Polycaprolactone as soft segments and Hexamethylene diisocyanate(HDI) as hard segments and the effect of soft segments’ composition on adhesion strength ofpolyurethane bioadhesivess was investigated. The chemical structure of cured bioadhesives wasstudied by (FTIR) test and the shear adhesion strength of polyurethane bioadhesives was examinedby Tensile test.
