Preparation and Characterization of PolyurethaneNanocopper Composites and Their Application in Intrauterine Devices

الملخص EN

A novel intrauterine devices material, polyurethane/nano-copper (PU/NC) nanocomposite, was prepared.

The structure, morphology, copper ion (Cu2+) release rate, and water absorption of PU/NC nanocomposites were investigated.

The results indicated that the nanocoppers were uniformly dispersed in the matrix.

The release rates of Cu2+ of PU/NC nanocomposites remained stable during the experimentation time.

These results indicated that the PU/NC nanocomposites have a great potential to replace current commercial intrauterine devices materials.
