摘要:
A method for preparing a modified silica film includes preparing a reactive fluorine-containing polymer solution by dissolving a reactive fluorine-containing polymer including a bonding group bondable to polysilazane in a fluorine-containing solvent, preparing a polysilazane solution by dissolving polysilazane in a solvent for polysilazane, the solvent for polysilazane being immiscible with the fluorine-containing solvent and exhibiting a higher surface tension than the reactive fluorine-containing polymer and the fluorine-containing solvent, preparing a coating liquid by mixing the polysilazane solution with the reactive fluorine-containing polymer solution, forming a coating layer by coating the coating liquid onto a substrate, removing the solvent for polysilazane and the fluorine-containing solvent from the coating layer, and converting the polysilazane into silica while bonding the bonding group of the reactive fluorine-containing polymer to the polysilazane.

Disclosed is a method for manufacturing a flame resistant and transparent film having a high transparency after imparting flame resistance through flame resistance treatment. The method for manufacturing the flame resistant and transparent film according to the present invention comprises the steps of: (a) preparing a transparent base film; (b) forming a flame resistant coating layer by coating a flame resistant material comprising a polysilazane onto at least one surface of the base film; (c) drying the flame-resistant coating layer so as to remove residual solvents in the flame-resistant coating layer; and (d) curing the flame-resistant coating layer under a humid environment. The present invention is characterized by the flame-resistant coating layer and a laminated body of the base film having an optical property in which a measured haze value is less than 0.3.

摘要:
The present invention provides a method for forming a siliceous film. According to the method, a siliceous film having a hydrophilic surface can be formed from a polysilazane compound at a low temperature. In the method, a composition containing a polysilazane compound and a silica-conversion reaction accelerator is applied on a substrate surface to form a polysilazane film, and then a polysilazane film-treatment solution is applied thereon so that the polysilazane compound can be converted into a siliceous film at 300° C. or less. The polysilazane film-treatment solution contains a solvent, hydrogen peroxide and an alcohol.
