Studies on structure and electromagnetic properties of ferrocenyl polymeric magnetic absorbent

The ferrocenyl acylhydrazone type coordinated metal polymeric absorbent(OPA-M) was synthesized.It was shown that its the largest reflective loss(R) is-15dB(6.9GHz) and the frequency wide is 4.2GHz(5.8-10GHz,R-10dB),when the substitutent is biphenyl growp and the coordinated metal is manganese in OPA-M.On the other hand,the largest reflective loss is-18dB(8.5GHz) and its frequency wide is 6.0GHz(5.5-11.5GHz,R -10dB) of the OPA-M composited absorbent with 3% carbon fiber,but their specific gravity is only 2.2.However,the new-generation polymeric magnetic absorbent will have important value in theory and military industry.
