Description
技术领域
本发明涉及一种三维纤维骨架多孔材料及其制备方法,属于新材料领域。
背景技术
三维多孔材料是一种由固体微粒或者纤维构成的三维聚集状态,其中内部含有大量气体作为分散介质,具有良好的隔热性能、吸噪性能,同时具有较小的密度。因此,三维多孔材料在能源催化、生物医疗、石油化工、航空航天、建筑材料、国防军工领域具有广泛的应用。现有三维多孔材料中,其骨架材料主要包括两类:固体微粒以及微纳米纤维。其中,以一维纳米纤维或纳米线构成的三维多孔材料的主要制备方法如下(Y.Si,J.Yu,X.Tang,J.Geand B.Ding,Ultralight nanofibre-assembled cellular aerogels withsuperelasticity and multifunctionality.Nat.Commun.5,5802(2014);Z.Yu,B.Qin,Z.Ma,J.Huang,S.Li,H.Zhao,H.Li,Y.Zhu,H.Wu,and S.Yu,Superelastic hard carbonnanofiber aerogels.Adv.Mater.1900651(2019)):首先将已制备的纤维或者纳米线分散在液相中形成悬浮液,再通过胶凝或冷冻使之固化,最后将其进行冷冻干燥或者超临界萃取除去溶剂,得到三维多孔材料。其存在的主要问题是,得到的三维材料中纤维较短,连续性差,纤维之间的作用力较小,造成其力学性能较差,并且制备工艺较繁琐,成本高。此外,也有文献报道(M.K.Joshi,H.R.Pant,A.P.Tiwari,H.J.Kim,C.H.Park,C.S.Kim,Multi-layered macroporous three-dimensional nanofibrous scaffold via a novel gasfoaming technique.Chem.Eng.J.275,79–88(2015);J.Jiang,Z.Li,H.Wang,Y.Wang,M.A.Carlson,M.J.Teusink,M.R.MacEwan,L.Gu,J.Xie,Expanded 3D nanofiberscaffolds:cell penetration,neovascularization,and hostresponse.Adv.Healthc.Mater.5,2993-3003(2016))将纤维膜置于溶液中,通过在溶液中快速的生成气体使纤维膜膨胀,最后通过冷冻干燥、真空干燥或超临界萃取形成三维多孔材料,但是该方法仍然存在制备过程复杂,成本高的问题。

本发明的三维纤维骨架多孔材料在惰性气氛下进行煅烧转变为三维多孔碳材料或三维多孔碳/无机物复合材料。
在惰性气氛下进行煅烧碳化按本领域的常规技术进行。
上述三维纤维骨架多孔材料的制备方法,包括步骤如下:

二维材料的膨胀及内部孔道的形成机理:由于二维材料是由多层纤维交联而成,当与相亲的液体接触时,液体在纤维表面浸润并在纤维之间形成液膜,当液相中物质因周围环境的变化发生化学反应产生气体时,液膜的存在使气体不能逸出,在内部产生气体压力,在该压力下纤维之间被拉伸并逐渐被气体填充,反应结束时形成的三维材料内部主要被气体填充,表面液膜仍然存在。
