【摘要】：實驗采用Fe~(3+)-H_2O_2催化氧化體系,以水為介質(zhì),十二烷基苯磺酸鈉(十二烷基苯磺酸鈉)為乳化劑,室溫下制備聚噻吩(PTP)有機蒙脫土(OMMT)復(fù)合材料。當(dāng)有機蒙脫土/聚噻吩=2g/ml時,反應(yīng)時間為12 h,制得復(fù)合材料電導(dǎo)率最高,其值為3.44×10~(-5)S/cm;在Fe~(3+)-H_2O_2和過硫酸銨(APS)兩種氧化體系下,分別采用苯胺(ANI)和吡咯(PY)對聚噻吩-有機蒙脫土進行修飾,制得聚苯胺-(聚噻吩-有機蒙脫土)和聚吡咯-(聚噻吩-有機蒙脫土)復(fù)合材料的電導(dǎo)率均達到10~(-2)S/cm~10~(-1)S/cm,較未修飾時提高了10~3倍~10~4倍。傅里葉紅外光譜(FTIR)和X射線衍射(XRD)表明噻吩(TP)進入有機蒙脫土層間聚合,形成插層復(fù)合,經(jīng)苯胺和吡咯修飾后,插層結(jié)構(gòu)沒有被破壞;重分析(TG)則證實復(fù)合后材料熱穩(wěn)定性得到提高,500℃時失重在11.69%左右,但經(jīng)修飾后材料的熱穩(wěn)定性有所降低500℃時失重達到80%以上。掃描電鏡(SEM)表明在Fe~(3+)-H_2O_2氧化體系下,經(jīng)修飾后材料形貌更規(guī)整,且均為球形。
[Abstract]:The organic montmorillonite (OMT) composite was prepared by using Fe~(3 / H _ 2O _ 2 catalytic oxidation system with water as the medium and sodium 12 alkylbenzene sulfonate (12 alkylbenzene sulfonate) as emulsifier at room temperature. When the organic montmorillonite / polythiophene was 2 g / ml, the organic montmorillonite / polythiophene montmorillonite was prepared at room temperature. When the reaction time was 12 h, the conductivity of the composite was the highest, with the value of 3.44 脳 10 ~ (-5) S / cm. The polythiophene / organic montmorillonite was modified by aniline ANI (aniline) and pyrrole pyrrolidine (Pyrrole) in the oxidation systems of Fe~(3 / H _ 2O _ 2 and ammonium persulfate respectively. The conductivity of Polyaniline (polythiophene organic montmorillonite) and polypyrrole (polythiophene organic montmorillonite) composites reached 10 ~ (10) ~ (-2) S / cm ~ (-1) ~ (-1) S / cm ~ (-1), 10 ~ (3) times and 10 ~ (4) times higher than that without modification. Fourier transform Infrared Spectroscopy (FTIR) and X-ray diffraction (XRD) were used to study the properties of polyaniline (poly (thiophene) -organic montmorillonite) and X-ray diffraction (XRD). The results of XRD showed that thiophene TPs were polymerized into organic montmorillonite interlayer. The intercalation composite was formed and modified by aniline and pyrrole, the intercalation structure was not destroyed, and the reanalysis confirmed that the thermal stability of the composite was improved at 11.69% 鈩，
