Graphene oxide/barium calcium zirconate titanate composite piezoelectric ceramic with good biocompatibility and preparation method thereof
The invention discloses a graphene oxide/barium calcium zirconate titanate composite piezoelectric ceramic with good biocompatibility and a preparation method thereof. A barium calcium zirconate titanate based ceramic (Ba0. 85Ca0. 15Zr0. 1Ti0. 9) O3 is prepared according to the following steps: 1) burdening, 2) ball milling, 3) drying, 4) calcining, 5) secondary ball milling, 6) drying, 7) sintering, and 8) grinding and sieving. And B, preparing the graphene oxide/barium calcium zirconate titanate composite piezoelectric ceramic according to the following steps: 1) burdening, 2) ball milling, 3) drying, 4) sieving and 5) sintering. The graphene oxide/barium calcium zirconate titanate composite piezoelectric ceramic is successfully prepared by combining a solid-phase sintering method and a rapid hot-pressing sintering method, the prepared composite ceramic sample is relatively uniform in crystal grain distribution, smaller in crystal grain size and high in density, and meanwhile, the composite piezoelectric ceramic can be applied to the field of piezoelectric ceramics. The wettability and the biocompatibility of the GO/BCZT composite piezoelectric ceramic material are relatively good. The material is expected to be further applied to the field of biological materials and bone defect repair.
