摘要: Abstract A new kind of thermosensitive magnetic particles with core/shell structure was prepared by copolymerization styrene (St) and N -isopropylacrylamide (NIPAM) in the presence Fe 3 O 4 fluid ethanol/water medium. The shrank above lower critical solution temperature (LCST) /P(St-NIPAM) swelled below LCST water. effect polymerization parameters such as initiator concentration NIPAM/St ratio on investigated. Higher formed larger particles, size decreased increased.
