Phase structure and micro-morphology of carbon nanotube film （CNTF） prepared with the chemical vapor deposition （CVD） method were characterized. According to the micro-structure characteristics of carbon nanotubes in CNTF， which are disordered and arranged irregularly， but have high porosity， the design scheme and preparation process of aircraft electro-thermal anti-icing system based on CNTF are proposed. In this program， light materials such as CNTF and epoxy resin were used， and the sample preparation process was discussed and optimized. The electro-thermal performance of this new type of electro-thermal anti-icing system''s sample was studied through the test of electro-thermal heating characteristics and anti-icing function tests. The results show that this new type of electro-thermal anti-icing system has simple structure and light weight， and is easy to be combined with aircraft aluminum alloy skin， which is conducive to reducing aircraft empty weight and flight cost. The effective average temperature obtained in the electric heating process is 47℃， which can effectively accelerate the melting of ice layer and has a good prospect in practical application.
