The present inventive concept relates to a mold and a construction panel manufacturing method using same, in which, in order to manufacture a construction panel, a surface on which a raw material is applied is formed into a curved surface by continuously connecting a rope. The mold comprises: first and second side plates facing each other; a curved base forming a predetermined curved surface between the first and second side plates by being interweaved to the first and second side plates; and a sheet member disposed along the curved base so as to form the curved surface, and enabling a construction panel raw material to be applied thereon. Thus, construction panels having variously-shaped curved surfaces may be manufactured by repeatedly using the first and second side plates while differing the interweaving of a rope so as to correspond to a curved surface of a construction panel to be manufactured. Accordingly, the present inventive concept has the effect of having excellent manufacturing efficiency for construction panels having curved surfaces.

Provided are a polymer thin-film transistor and a method of fabricating the same. Donor-acceptor copolymer-based field-effect transistors (FETs) have attracted considerable attention from technological and academic perspectives due to their low band gap, high mobility, low cost, easy solution processability, flexibility, and stretchability. Large-area films can be formed through meniscus-guided coating among various solution-processing techniques. 29-Diketopyrrolopyrrole-selenophene vinylene selenophene (29-DPP-SVS) donor-acceptor copolymer-based FETs have already shown excellent performance due to their short π-π stacking distance and strong π-π interaction. Charge carrier mobility of these types of semiconductor materials significantly depends on an applied electric field. Accordingly, detailed analysis of the electric-field dependency of charge carrier mobility is necessary to understand the transport mechanism within the material. Therefore, 29-DPP-S VS-based FETs are fabricated by varying the blade coating (BC) speed of a semiconductor layer. The effect of the BC speed on the electrical characteristics of the FETs is studied through the analysis of electric-field-dependent mobility. The results show that the charge carrier mobility of different FETs depends on the applied electric field and that the type of dependency is Poole-Frenkel. At an optimized BC speed (2 mm s −1 ), the device shows maximum zero-field mobility (3.39 cm 2 V −1 s −1 ) due to the low trap density within the conductive channel.
