D-tartaric acid 2,2-bipyridine amine cobalt ferroelectric functional material and its preparation method (by machine translation)
The invention discloses a D-tartaric acid 2,2-dipyridylamine cobalt ferroelectric function material and a preparation method. The molecular formula is [Co(dpa)(D-C4H4O6)]2.8H2O, wherein dpa is 2,2-dipyridylamine; the ferroelectric function material is monoclinic system powder of which the purity is not lower than 99%; the structure of space group is C2; the ferroelectric characteristic parameters are as follows: the remanent polarization strength 2Pr=0.05(mu)C.cm<-2>, coercive electric field 2Ec=15.2kv.cm<-1>, and saturization polarization strength Ps=0.249(mu)c.cm<-2>; and the ferroelectric function material has relatively good ferroelectric characteristics. The preparation method of the ferroelectric function material comprises the following steps of: enabling the newly prepared cobalt carbonate to react with the mixed solution of D-tartaric acid 2,2-dipyridylamine to obtain a D-tartaric acid 2,2-dipyridylamine cobalt solution; devitrifying; and grinding to obtain ferroelectric function material powder passing through a 100-mesh sieve. The method has the advantages of few processes, simple technology, low requirements on equipment, cheap materials of cobalt salt and tartaric acid, no pollution, low cost and easiness in realizing industrialization.
I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 499-40-1, help many people in the next few years., Reference of 499-40-1
