| Summary: | This work investigated the properties of the polyurethane/neoprene/graphene nanocomposites blends specifically in mechanical and thermal aspects for solid ankle cushion heel
(SACH) foot in the prosthetic application. The aim of this work was to study the effect of
neoprene and graphene contents in mechanical and thermal properties of
polyurethane/neoprene/graphene blends. Polyurethane is one of the most frequently used
polymers in the medical devices, footwear, automotive and construction industries.
Polyurethane which is high mechanical strength, high thermal withstands and flexibility was
blended with the additives, neoprene and graphene to reduce the rigidity and enhances the
mechanical properties for a prosthetic foot. A solution mixing method was used to prepare the
samples with different formulations of polyurethane, neoprene and graphene. The samples
were analyzed and characterized in terms of mechanical, thermal and morphology properties.
The result shows that the optimum composition blended with 97 wt% polyurethane, 2 wt%
neoprene and 1 wt% graphene. The sample possesses high tensile strength (14.38 MPa) and
high Young’s modulus (1.11 MPa), high thermal stability, elastic and flexible. The use of a low
amount of graphene in polyurethane and neoprene blend has been demonstrated to enhance the
mechanical and thermal properties of the nanocomposites. |
