Abstract
Magnetic nanocomposites on the basis of water soluble unsaturated polyester resin filled with different amount of iron oxide nanoparticles have been successfully prepared. The mechanical properties of thus prepared composites as tensile, impact and flexural strength were determined. The specific volume and surface resistance of the magnetic nanocomposites were also determined.
Highlights
R ecently, great scientific and technological interest has been paid to the magnetic nanoparticles because of their unique properties and various applications [1,2,3,4,5,6]
The obtained emulsion is stable enough with the time in order to undergo various technological processes. It is known the preparation of suspension copolymerization of unsaturated resins with styrene and acrylonytrile using a redox system consisting of metylketohydroperoxide and cobalt naphtenate [17]
The copolymerization of the unsaturated polyester resin containing 44% styrene was performed using different amount of initiator in order to determine the time for reaching the optimal copolymerization temperature during the process (Fig. 2)
Summary
R ecently, great scientific and technological interest has been paid to the magnetic nanoparticles because of their unique properties and various applications [1,2,3,4,5,6] They can be synthesized using different methods such as microemulsion [7], sol-gel synthesis [8], sonochemical reactions [9], hydrolysis [10] and thermolysis [11]. The obtained emulsion is stable enough with the time in order to undergo various technological processes It is known the preparation of suspension copolymerization of unsaturated resins with styrene and acrylonytrile using a redox system consisting of metylketohydroperoxide and cobalt naphtenate [17]. The mechanical properties of the prepared magnetic nanocomposites will be investigated as well
