By combining PP and Maghnite with an epoxy resin (EP), innovative nanocomposite materials was developed. With different blend compositions, the effect of EP on the mechanical properties, polarisation tests, salt spray tests and morphological characteristics of the blends was studied. The storage modulus (E′) of EP is 2179 MPa, which increases to 2361 MPa with increasing PP-Mag content. The mechanical properties of the blends containing EP/wt%PP/Mag showed an improved performance due to a better adhesion between the two phases when EP is incorporated. It was shown that the PP/Mag materials present in the matrix improve the corrosion resistance according to the different polarisation tests and the salt spray test.
