Structural characterization of APPJ treated Bismaleimide coatings and heat treated Titania-BMI

Bismaleimide (BMI) are thermosetting polymers mainly used in aerospace applications having properties of dimensional stability, low shrinkage, chemical resistance, fire resistance, good mechanical properties and high resistance against various solvents, acids, and water. BMI is commercially available as Homide 250. BMI coating has also been used for the corrosion protection. Metallization (AL) of BMI using vacuum evaporation was done which serves the purpose of prevention of space charge accumulation in aircraft bodies. Addition of inorganic materials like metal oxides can influence the properties of the polymer as an inorganic-organic composite. The organic-ionorganic composites have wide applications in electronics, optics, chemistry and medicine. Titanium dioxide (TiO2, Titania) has a wide range of applications starting from photocatalysis, dye-sensitized solar cells to optical coatings and electronics. A BMI-TiO2 composite was prepared by chemical route. Atmospheric Plasma Jet (APPJ) using Helium gas was also treated on BMI. XRD and FTIR studies of the composite system prepared at different temperatures showed its crystalline and structural configuration.
