Physico-chemical properties of MNP dispersed in water (MNP disp) and hybrid filaments (PP@3%MNP, PP@5%MNP, and PP@7%MNP): iron concentration cFe, core diameter dcore (for the filaments the major and minor axis of agglomerates is specified), hydrodynamic diameter dh, crystal diameter dcryst, magnetic diameter dm, saturation magnetization MS, and maximum temperature TM in the ZFC curve. σ denotes the standard deviation.
