The θr represents the recovered angle as well as the schematic illustration of a condition memory bending cycle is proven inside the supplementary details (Figure S2).
A normal form memory process of the polyimide was performed as follows: ① the flat polyimide lath was bended at Tg + 20 °C; ② it had been cooled to room temperature With all the deformation stress and the temporary form was fastened; ③ the short term form was heated to Tg + twenty °C and it recovered to its initial form.
