Triethynylborazine-polyhydromethylsiloxane copolymers (TEB-PHMSs) were prepared through hydrosilylation reaction between -C≡CH attached to boron and ≡Si-H. The structures of TEB-PHMSs were characterized by Fourier transform Infrared (FT-IR) and Nuclear Magnetic Resonance (NMR) spectroscopy. Their cure behavior were examined by Differential Scanning Calorimeter (DSC) and FT-IR, and then thermostability and ceramization of cured TEB-PHMS were investigated by Thermogravimetric analysis (TGA), pyrolysis-GC-MS, X-ray diffraction (XRD) and Scanning Electron Microscopy (SEM). The results indicated that TEB-PHMSs could be cured and converted into an outstanding thermostable SiBCN ceramics.

Polypyrrole/montmorillonite (PPy/MMT) particles were synthesized using an oxidative polymerization method. Then the particles were added into polymethyl methacrylate (PMMA) as additives to prepare PPy/MMT/PMMA composite. The structures and properties of the composite were characterized by FT-IR, TGA, X-ray diffraction spectroscopy, and four–probe machine. The relationship between content of PPy/MMT and conductivity was analyzed. The result shows that the amount of PPy/MMT is a key factor for improving the conductivity of composite. Furthermore, dynamic mechanical (DM) properties of composite were studied. When the PPy/MMT content reach 0.2% of composite, the storage modulus, loss function modulus, dissipation factor get highest values.

Polyvinyl alcohol- polypyrrole (PVA-PPy) nanocomposites with metal chlorides (FeCl3, NiCl2, CuCl2 and ZnCl2) have been synthesized by chemical oxidative polymerization method. These synthesized nanocomposites are characterized by using FTIR, X-ray diffraction, Transition electron microscope (TEM) and Conductivity measurement. TEM exhibit that all of the composites have uniform sizes and morphologies.  The diameter of PVA/PPy nanocompsite is 58nm when the metals added to the PVA/PPy the diameters becomes smaller. The variation of electrical conductivity (log ?) with 1000/T for PVA/PPy nanocomposite with metal chlorides revealed that the increase in conductivity s at temperature (393K) with added metals can be attributed to the creation of induced charge carriers in PVA/PPy matrix

Telah dilakukan sintesis fotokatalis N/TiO2 bermofologi nanotube dengan metode anodisasi  menggunakan ammonium nitrat (NH4NO3) sebagai sumber dopan pada berbagai variasi konsentrasi (0,5M , 1M, 2M), dilanjutkan dengan kalisinasi pada suhu 4500C selama 2 jam untuk mendapatkan fasa kristal anatase. Karakterisasi dilakukan menggunakan Scanning Electron Miscroscopy (SEM), Fourier Transform Infra Red (FT-IR), X-ray Diffraction (XRD), dan DRS (Diffused Reflectant Spectrometry) UV-Vis. Pengujian Linear Sweep Voltametri dan Multi Pulse Anperiometri pada fotokatalis­ N/TiO2 telah berhasil diterapkan untuk degradasi senyawa Rhodamin B menggunakan sinar UV maupun sinar tampak. Aplikasi dari uji fotoelektrokatalisis menggunakan sinar tampak untuk N/TiO2-NT memberikan hasil eliminasi sebesar 47,86%, sedangkan bila menggunakan TiO2 nanotube tanpa dopan eleminasi hanya sebesar 25,49%. Hal ini menunjukkan bahwa proses doping yang dilakukan telah berhasil menyisipkan nitrogen kedalam matrik TiO2 nanotube dan memperbaiki kinerja fotokatalisis nya di daerah sinar tampak.

A chemical oxidative polymerization of aniline sulfosalicylic acid (ANISSA) and aniline sulfate acid (ANIH2SO4) was performed in an aqueous solution. A co-doped polyaniline (PANI) was thus obtained, a higher conductivity than the insoluble H2SO4-doped PANI compressed pellet, and much higher conductivity than that prepared from pure ANISSA. The PANI doped with SSA and H2SO4 was characterized using Fourier-transform infrared spectra (FTIR), Fourier-transform Raman spectra (FT-Raman), X-ray diffraction (XRD) and thermogravimetric analysis (TGA). The investigation reveals that SSA and H2SO4 as dopant not only enhances crystallinity of polyaniline but also stability of polyaniline.

Polyaniline/tungsten carbide (PANI/WC) composite was synthesized by chemical oxidative polymerization of aniline using ammonium persulfate as the oxidant and thermal treated in air at 150°C, 250°C, 350°C and 450°C to 2 hours. The changes of structure, crystalline and conductivity were investigated by Fourier Transformed Infrared (FT-IR), Fourier Transformed Raman (FT-Raman), X-Ray Diffraction (XRD) and four-probe technique. The results showed that PANI/WC composite showed much-improved thermal stability compared to pure PANI. But the conductivity of PANI/WC is reduced to some extent (1.73 S/cm, the conductivity is reduced by about 82%) after thermal treated at 250°C, and dropped by 6 orders of magnitude (3.25×10-6S/cm) at 350°C. This may be explained by that only a fraction of dopant losses during thermal treatment at 250°C, but after thermal treatment at 350°C, along with cross-linking, chain scission and oxygen, resulting in destruction of crystal structure, decrease of the emeraldine sequence.
