天然生物材料的多级结构、微组装和仿生研究

Assembled microstructure characterization of Mytilus Edulis shells, Ostrich.Eggshells and Antheraea Pernyi Silk fiber etc. were deeply studied and modulation.of mineral phases by protein and collagen in the biomaterials were also investigated;.Nanoscaled multilayers of a hard composite ceramic (TiC) with a serious soft.component metal in six systems were exactly prepared to mimetic natural nacre.structure on the nanometer scale, and the hardness enhancement and its rules.occurred in the multilayers were identified ; Design and preparation of laminated.biomimetic composite of aluminum oxide/polymer were carried out; The effect of.environmental factors (exogenous magnetic field and electric field), solution.conditions and surface-modification etc. on mineralization were comprehensively.investigated in Ca-P salt system; Development of self-assembly methodology were.greatly performed and several kind of novel functional materials, such as.HAP/collagen nano-multilayer materials, mesoporous nano-lamellar metal oxides,.nanoparticles, nanofibers and heterogeneous nanoparticle/mesoporous oxide.composites, etc., were synthesized by those novel self-assembled process and the.formation mechanism and special properties for the synthesized composites were.investigated also; Development of biomimetic nano-laminated structural composite.SiN4/SiN4-SiC were carried out by three-dimension gel-casting approach.
