In recent years, carbon materials are widely investigated because of their extraordinary chemical, electrical and physical properties. But most of the researchers utilizes graphite, graphene, reduced graphene oxide (rGO), carbon nanotubes (CNT), etc., as carbon material due to their excellent aforsaid properties.   Keeping this in mind, we have syntheized the candle carbon soot using candle flame at room temperture conditions. We have  observed that a simple flame of candle is used to synthesize the layers of carbon soot  on desired substrate. This synthesis method has become an alternative rote for the preparation of carbon nanomaterials because of its advantages of low cost and mass production. Also, we have investigated , the acid treatment of candle soot is drastically improved their structural and electrical  properties as compared to as-synthesized soot. The effect of  acid functionalization on the  candle soot structure were investigated by X-ray diffraction (XRD) and Raman spectroscopy. This material has potential application in battery, photovoltaic cell, electronics and sensor.
