Influence of Porosity on the Mechanical Properties of Cu/LDPE Porous Composites for Intrauterine Contraceptive Devices

Abstract:

As a novel Cu-IUD material, it is necessary for copper/low-density polyethylene (Cu/LDPE) porous composite to have some suitable mechanical properties if it is used to prepare a clinical Cu-IUD with frame. However, it is not clear how the porosity of the porous structure affects the mechanical properties of Cu/LDPE porous composites. Therefore, the influence of the porosity of porous structure on the mechanical properties of Cu/LDPE porous composites is investigated in the present paper. The results show that the porosity has significant effects on the mechanical properties of Cu/LDPE porous composites. The mechanical properties of the Cu/LDPE porous composites decrease with the increasing of porosity, for the effective load area decreases, the chance for occurrence of cracks increases and the crystallinity degree of LDPE matrix increases with the increasing of porosity. These results are very important and they can be applied to guide the design of Cu/LDPE porous composite IUD for use in the future clinical application.
