　　與常規(guī)材料相比,沸石咪唑酯骨架結(jié)構(gòu)材料（ZIFs）可以說(shuō)是一類新型的金屬有機(jī)骨架,它含有咪唑化物連接基和金屬離子以及類似鋁硅酸鹽沸石的結(jié)構(gòu)。多年來(lái),越來(lái)越多的人對(duì)ZIF產(chǎn)生了興趣,其固有的多孔特性以及出色的化學(xué)性質(zhì)和可控的結(jié)構(gòu)特征導(dǎo)致在氣體吸附,分子傳感,能量存儲(chǔ)設(shè)備,光電,催化,生物醫(yī)學(xué),藥物負(fù)載,磁性能以及電磁屏蔽和隱身技術(shù)等領(lǐng)域得到了廣泛的應(yīng)用。此外,ZIF基材料可作為出色的模板,用于生產(chǎn)多孔碳和相關(guān)的納米結(jié)構(gòu)復(fù)合材料,這些復(fù)合材料具有較大的表面積,均勻的孔,平衡的金屬/有機(jī)比以及相對(duì)于其骨架而言可控的結(jié)構(gòu)。近年來(lái),人們?cè)谶@一快速發(fā)展領(lǐng)域中專注于先進(jìn)的合成方法以及有吸引力的應(yīng)用研究。本文主要研究ZIFs的制備,納米結(jié)構(gòu)復(fù)合材料以及ZIFs的應(yīng)用。研究了 ZIFs的合成方法,形貌,結(jié)構(gòu)性質(zhì),詳細(xì)討論了磁性,聲子限制,超級(jí)電容,電子極化,電磁波吸收和屏蔽。本文的研究部分主要包括以下五個(gè)方面:（1）異質(zhì)結(jié)構(gòu)的TiO2/C/Co納米材料是由碳化的沸石咪唑酸鹽（ZIF-67）多孔骨架衍生而來(lái),獲得了包覆有TiO2的均勻納米球結(jié)構(gòu),顯示出了優(yōu)異的微波吸收性能。迄今為止,在傳統(tǒng)層面尚未在文獻(xiàn)中...
