Abstract

The advancement of technology in inorganic polymers and their application in diverse sectors like electronics, medicine, and defense has experienced significant growth. Studies indicate that artificially created inorganic polymers can display distinct physical and chemical characteristics. Among these, polyphosphazenes stand out as a widely explored category, with over seven hundred polymers successfully synthesized. These polymers possess exceptional attributes such as self-extinguishing behavior, hydrophobicity, and biocompatibility, making them a focal point for researchers in the field of polymer science. The distinctive features are attributed to the phosphazene main chain, which incorporates two side groups in each repetitive unit, allowing for the substitution with other organic compounds to manifest various specific properties.

Abstract

Fabrication with carbon-modified TiO2 by arc  discharge  method  in  liquid  medium has  been  studied.  This  research  was  performed  in  two  steps  including  fabrication  and characterization.  This  fabrication  was  done  by  arcdischarge  method  with  graphite electrodes from dry cell batteries and liquid medium suspension of TiO2 in ethanol 30, 50 and  70  %.  A  strong  current  was  applied  to  electrode  as  10 -50  A  (20-40  V). Nanocomposites formed  on  the  liquid  medium  surface  were  collected  and  characterized using X-ray  diffraction (XRD),scanning  electron  microscope (SEM)  dan energy  dispersive spectroscopy (EDS) to determine crystallinity, surface morphology and the constituent elements, respectively.  XRD  data  shows  that the  most  effective  fabrication  TiO2/Karbon by  liquid medium in ethanol 50  %  indicated  from  the formation of a new peak with high intensity  of TiC on 2Ɵ= 36.02 °. SEM data shows that the morphology of each aggregated TiO2/Karbon  compared  to  the  morphology  of  TiO2. In  addition,  EDS  data  shows  the presence of the element carbon, titanium and oxygen  in the same area  indicating that the successful formation of composite material between TiO2 dan carbon.
