Abstract: An automatic carton forming device includes a supporting table, a storage rack, a limiting part, a transporting part, and a folding part. The storage rack is configured to store folded paper boards, the limiting part is configured to limit the folded paper boards, the transporting part includes a moving base and a driving unit for driving the moving base to move. At least one first vacuum suction cup is disposed on the moving base, the limiting part includes an adsorbing base disposed on one end of the supporting table, at least one second vacuum suction cup is disposed on the adsorbing base. The folding part includes a first overturning plate, a vertical folding unit, a transverse folding unit, and a transmitting unit, and the transmitting unit drives the first overturning plate, the vertical folding unit, and the transverse folding unit to perform folding action.

Abstract: A terminal functional side chain-substituted diketopyrrolopyrrole (DPP)-based terpolymer and a preparation method and use thereof is described herein. The terpolymer has the following structural formula: where R1 is a terminal siloxy-substituted swallow-tailed chain with 22 to 52 carbon atoms in total, and t1 and t2 each are an integer of 1 to 18; R2 is a semifluoroalkyl-substituted swallow-tailed chain with 12 to 60 carbon atoms in total and 10 to 46 fluorine atoms in total, t3 and t4 each are an integer of 1 to 16, and t5 and t6 each are an integer of 1 to 10; and Ar is any one selected from the group consisting of aryl, heteroaryl, substituent-containing aryl, and substituent-containing heteroaryl, and m and n each are an integer of 5 to 100.
