Abstract: An air control system and method using air in an upper zone of the atmosphere are disclosed. An air control system using air in an upper zone of the atmosphere includes: a floating body 11 provided to stay in the upper zone of the atmosphere; air transporting pipes 15a and 15b interlocked with the floating body 11 to transport air in the upper zone of the atmosphere; blowers 22a and 22b mounted below the air transporting pipe 15a and 15b; and an air transporting controller 18 controlling an operation of the blowers 22a and 22b. According to the embodiment of the present invention, it is possible to implement functions such as cooling, drying, and purifying of the surrounding air, removing mist, or generating clouds through the transport of dry and low-temperature clean air in the upper zone of the atmosphere with a simple structure. In addition, according to the embodiment of the present invention, it is possible to freely adjust a height of air control because there is no need to install a post tower to support an elevating device because it supports the floating body 11 on the ground without the post tower.

Abstract: A flexible triboelectric nanogenerator (TENG) has attracted much attention due to its environmentally friendly, practical, and cost-producing advantages. Flexible electrodes are required to fabricate a fully flexible TENG device. Electrical properties of porous polydimethylsiloxane (PDMS) sponge-based flexible TENGs with two types of flexible electrodes including copper and carbon nanotube (CNT)-PDMS were compared. Output voltages and maximum power densities of the PDMS sponge-based flexible TENGs with the copper and CNT-PDMS electrodes were compared. The voltage and the power density of the PDMS sponge-based flexible TENG with the CNT-PDMS electrodes were shown to be improved compared to the copper electrodes. The output voltage and the maximum power density of the PDMS sponge-based flexible TENG with the CNT-PDMS electrodes increased 4 times and 7 times, respectively, compared to the PDMS sponge-based flexible TENG with the copper electrodes because electrical conductivity is higher and electricity more stably flows in CNTs than in copper.

Abstract: 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 cm2V−1s−1) due to the low trap density within the conductive channel.
