Microhardness of Metal–Polymer Composites Based on Polymer Track Membranes and FeNi Nanowires

Metal–polymer composites have been obtained by matrix synthesis in pores of track membranes with different times of filling pores with permalloy. The geometric parameters of the resulting arrays of nanowires, which were the functional filling of composites, were determined using scanning electron microscopy. The microhardness of the nanocomposites was studied by the nanoindentation method. A relationship between the increase in the microhardness of the metal–polymer composite and the degree of filling the matrix is established. It is suggested that there is a relationship between the composite hardness and the number of intersections of nanowires in the matrix.
