The present disclosure provides a method for manufacturing an aerogel blanket, wherein a surface modification process is performed under acid conditions while using a non-toxic catalyst. Under such a process, a solvent substitution process or a washing process may be omitted to simplify the manufacturing process. Further, collapse of a gel structure due to shrinkage is prevented and the efficiency of surface modification is high even when atmospheric pressure drying is performed, so that an aerogel having excellent thermal conductivity and degree of hydrophobicity may be manufactured. Also provided is an aerogel blanket manufactured by the method, thereby having low thermal conductivity and a low moisture impregnation rate since a hydrophobic group is uniformly formed inside a substrate.

Method and apparatus for producing metal-coated optical fiber involves providing a length of optical fiber having a glass fiber with or without a carbon layer surrounded by a liquid-soluble polymeric coating. The optical fiber is passed through a series of solution baths such that the fiber will contact the solution in each bath for a predetermined dwell time, the series of solution baths effecting removal of the polymer coating and subsequent electroless plating of metal on the glass fiber. The optical fiber is collected after metal plating so that a selected quantity of the metal-coated optical fiber is gathered, Preferably, the glass fiber passes through the series of solution baths without contacting anything except for the respective solution in each.

There is disclosed a method for chemically treating a display glass substrate by treating at least one surface of the glass substrate with a heated solution containing HCl to form a depletion layer at the surface and under the surface of the glass substrate. The disclosure also relates to display glass substrates containing the depletion layer made by the disclosed process. In addition, the disclosure relates to methods of making thin-film transistors (“TFTs”) on these display glass substrates by depositing a Si layer directly on the chemically treated surface of the glass substrate, and annealing the Si layer to form polycrystalline silicon.
