2023年12月13日 · Polypyrrole (PPy) is a conductive polymer known for its biocompatibility and ease of synthesis. Chemically polymerized PPy was synthesized in the presence of sodium dodecyl sulfate (SDS), showing correlations among chemical properties, physical morphology, and electrical properties.

Nano-scaled polypyrrole (PPy) particles have been successfully synthesized with the help of Triton X-100 micelles via soft template approach. The polypyrrole...

2015年9月13日 · Polypyrrole (PPY) powder was chemically synthesized using ferric chloride (FeCl3) and characterized by X-ray diffraction (XRD), Le Bail Method, Fourier Transform Infrared Spectrometry (FTIR), and Sca...

2023年2月10日 · As indicated by scanning electron microscopy (SEM), PPy tends to form randomly distributed particles in an aqueous media without the nanofiber template (Fig. 1b). On the other hand, in the...

1 天前 · In the case of PPy (Fig. 1b), SEM image explores the agglomerated surface composed of spherical and patchy grains with porous nature. PEDOT-PPy produced the coarse morphology as shown in Fig. 1 c.

2015年9月13日 · 使用氯化铁（FeCl 3 ）化学合成聚吡咯（PPY）粉末，并通过X射线衍射（XRD），Le Bail方法，傅立叶变换红外光谱（FTIR）和扫描电子显微镜（SEM）对其进行表征。

The SEM indicates that CuO nanoparticles cause a homogenous PPy morphology due to the reduction of the accumulation by incorporation of CuO in PPy.

2024年5月16日 · 水溶液中的吡咯单体 (mPPy) 用于在室温下通过化学氧化聚合过程在几个小时内生成导电聚合物聚吡咯（均聚 PPy）。 使用氯化铁(FeCl 3 )氧化剂，十二烷基硫酸钠(C 12 H 25 NaO 4 S)表面活性剂。

2019年1月1日 · We have studied morphological and optical properties of PPY samples by varying the monomer to oxidant molar ratio as 1:1.25 and 1:2 and denoted the samples by 1125ppy and 1200ppy respectively. The prepared samples are characterized by FTIR, UV-Vis, photoluminescence (PL) spectroscopy and FESEM.
