제목 Synthesis and characterization of colorless poly(amide-imide) film for flexible display
초록 Colorless poly(amide-imide) (PAI) film was synthesized and characterized. Charge transfer complex (CTC) of the conventional polyimide (PI) was decreased by adding amide group beside imide ring. The amide groups act as an electron withdrawing group in polymer chain and they reduce the electron density in PAI. As CTC decreased, the color of the film changed from brown to colorless. Also, PAI has lower residual stress than PI because of steric hindrance of the amide group. Due to low residual stress, PAI film is less likely to crack and has high reliability. Synthesized PAI film in this work is expected to be used in flexible display.
