摘要：将四-二乙氨基锆(TDEAZ)和乙炔基苯胺封端的聚碳硅氮烷(PCSN)进行液相共混,制备含有Zr、Si元素的新型复相陶瓷先驱体(ZPCSN),并通过FT-IR对其结构进行表征,利用DSC与TGA分别探讨其固化行为及耐热性能;并通过XRD与EDS研究ZPCSN的陶瓷先驱体、耐高温陶瓷。陶瓷化性能结果表明,ZPCSN结构中含有C≡C键,在固化过程中交联形成致密的三维网状结构,赋予ZPCSN优异的耐热性能;在1 600℃氩气氛围中,ZPCSN裂解形成Zr C/Zr N/Si C/Si3N4多元复相陶瓷,保留率为67.92%,这表明ZPCSN具有优异的陶瓷化性能。
The new composite ceramic precursor（ ZPCSN） containing zirconium and silicon was prepared by blending tetrakis（ dimethylamido） zirconium（ TDEZAZ） with phenylacetylene（ PCSN）. The structure of ZPCSN was characterized by FT-IR; the curing behavior of ZPCSN was analyzed by DSC and its thermal stability was studied by TGA; its ceramization performance was investigated by XRD with XPS. The results show that ZPCSN can form dense three-dimensional network structure by cross-linking in curing process and possess excellent heat resistance owing to the alkynyl in the molecular structure; in addition,ZPCSN can turn into multiple complex phases ceramics composed of Zr C,Zr N,Si C and Si3N4 with a yield of 67.92%after sintering at 1 600 ℃ in argon,thus it indicates that ZPCSN exhibits excellent ceramization performance.
