我们感兴趣的另外一大类生物材料是具有层状结构的有机/无机复合材料, 如Al2O3/PMMA。这类新材料具有很强的机械性能如模量,抗张强度,以及断裂韧性。这类材料通常通过(1)冰模板法(ice-templating, also called freeze casting)制备生物陶瓷的层状结构,(2)然后通过真空把高分子聚合单体渗透到层状结构里聚合。这类新材料由于有出色的力学性能,很可能由此作为模板/支架,生长出力学性能高的骨。由于骨用生物材料是一个交叉学科,我们会与国内外化学家,细胞生物学家,外科医生,以及医院(如北京积水潭医院)通力合作,评价这些生物材料的动物体外,体内性能。
在方向2上,我们的最终目的是制备,开发出工业界有用的高分子新材料包括纳米复合材料以及共混物。感兴趣的体系包括聚酰胺如Nylon 6, Nylon 6,6, 和Nylon 12,12, 通用塑料如聚乙烯及聚丙烯,以及一些生物降解高分子材料如聚乳酸。增强剂包括石墨烯,碳纳米管,纳米石墨及炭黑,纳米银离子,纳米碳酸钙,有机蒙脱土,纳米氧化硅,纳米氧化锌,纳米二氧化钛等等。增韧剂如乙丙橡胶,SEBS,乙辛橡胶等。这些纳米复合材料主要由高分子熔融加工法制备。材料的机械性能包括增韧与增强,电性能,导热性能,阻燃性能,以及传输性能是我们特别关注的。我们与北京工商大学,北京航空航天大学,清华大学,中科院工程塑料中心,中国科学院高分子化学与物理重点实验室,以及企业界有广泛的交流与合作。此外,我们也与美国著名大学如University of Texas at Austin, University of Minnesota, Massachusetts Institute of Technology, 以及Washington State University 有交流与合作。
