  • Patent number: 8834755
    Abstract: Disclosed are wholly aromatic polyamide filament and a method of manufacturing the same, characterized by comprising multi-stage injection of a coagulant with sulfuric acid concentration lowered sequentially stage by stage, to a spun material fed into a coagulant injection tank. The present invention enables increase of a spinning and take-up velocity without occurrence of thread cutting by uniformly and evenly coagulating surface and inside of the spun material. In addition, the present invention recovers the coagulant or water already used and reuses the recovered coagulant or water in the earlier stages, so that it has advantages of saving production costs and reducing environmental contamination. Accordingly, the wholly aromatic polyamide filament produced according to the present invention has high crystallinity X, large apparent crystal size ACS and reduced defects in the crystal itself, thereby exhibiting more improved physical properties such as strength and modulus.

  • Patent number: 8735229
    Abstract: A ZnO-based thin film transistor (TFT) is provided herein. Also provided is a method for manufacturing the TFT. The ZnO-based TFT is very sensitive to the oxygen concentration present in a channel layer. In order to prevent damage to a channel layer of a bottom gate TFT, and to avoid a deep negative threshold voltage resulting from damage to the channel layer, the method for manufacturing the ZnO-based TFT comprises formation of an etch stop layer or a passivation layer comprising unstable or incompletely bonded oxygen, and annealing the layers to induce an interfacial reaction between the oxide layer and the channel layer and to reduce the carrier concentration.
