发明名称 Simple method for introducing magnetic particles into a polymer
摘要 The present invention provides a simple method for introducing magnetic particles into a polymer for further preparing a magnetic polymer, the method using the capability of polymer to absorb Fe3+ and other divalent metal ions M2+, adding alkali immediately each time after absorbing Fe3+ or M2+, thereby generating hydrated oxide of the Fe3+ and hydrated oxide of the divalent metal ions in sequence inside the polymer, and then heating, so that the hydrated oxide of the Fe3+ and the hydrated oxide of the divalent metal ions are transformed into magnetic particles MFexOy, where M may be Fe2+, Zn2+, Mg2+, Cu2+, Ca2+, Ba2+, Sr2+, Ni2+, Co2+, Mn2+ and the like, and x=1.0˜2.0; y=3.0˜4.0. Compared with the prior art method, the present one is simpler, wider in application, and more operable.
