ABSTRACT

Three compositions of glycidyl methacrylate and styrene were added with Fe3O4, ethylene glycol dimethacrylate (EGDMA), poly vinyl alcohol (PVA) and 2, 2-dimethoxy-2-phenylacetophenone (DMPP). Fe3O4 were dispersed within monomers and were exposed to the ultraviolet radiation for polymerization process. The Fe3O4 particles were introduced to enhance physical and chemical properties of the polymers. The thermal properties of polymer were improved after addition of styrene and Fe3O4. Vibrating sample magnetometer (VSM) also exhibits copolymer with soft ferromagnetic properties. Field emission scanning electron microscopy (FESEM) showed the size of magnetic polymer microspheres were from 0.5 to 1.5 μm. The rough surface was also observed due to the presence of styrene.

ABSTRAK

Tiga komposisi glisidil metakrilat dan stirena ditambah dengan Fe3O4, etilena glikol dimetakrilat (EGDMA), poli vinil alkohol (PVA) dan 2,2-dimetoksi-2-fenilasetofenon (DMPP). Fe3O4 disebarkan di dalam monomer dan didedahkan kepada sinaran ultra lembayung untuk proses pempolimeran. Zarah Fe3O4 dimasukkan untuk meningkatkan sifat fizik dan kimia polimer. Sifat terma polimer meningkat selepas penambahan stirena dan Fe3O4. Magnetometer sampel bergetar (VSM) juga mempamerkan kopolimer bersifat ferromagnet lembut. Mikroskop elektron imbasan pancaran medan (FESEM) menunjukkan saiz mikrosfera polimer bermagnet ialah daripada 0.5 hingga 1.5 μm. Permukaan kasar juga diperhatikan kerana kehadiran stirena.
