Synthesis of Magnetite–PAM-Silica hybrid Composites

This paper evaluates a general methodology for the synthesis of Magnetite–PAM-silica particles, which is based on the entrapment of a hydrophilic organic polymer in a polycondensation silica networking. Having a silica surface is advantageous, in that it stabilizes the silica particles, makes them biocompatible and gives opportunity to further modify and tag functional groups via the well established silica surface chemistry. Here the successful achievement of that goal was reported by illustrating the synthesis of poly(acrylamide)-silica submicrometer particles from the cheaper sodium silicate precursor. However, finding the right conditions for preparing these composites required screening of many procedures, some of which are briefly mentioned here
