manufacturing method of hybrid packaging materials for insulation and corrosion proof in flexible energy devices

The present invention relates to a manufacturing method of a hybrid packaging material for insulation and corrosion prevention of a flexible energy device, and has a technical subject matter providing a manufacturing method of a hybrid packaging material for insulation and corrosion prevention of a flexible energy device including: a first step of forming colloidal inorganic nano-sol; a second step of treating a surface of the inorganic nano-sol in a way of adding functional organic metal alkoxide containing an organic functional group to the inorganic nano-sol of the first step and stirring the mixture to form a surface-treated inorganic nano-sol; and a third step of preparing oligosiloxane by adding organic silane to the surface-treated inorganic nano-sol of the second step and making the organic silane react with the surface-treated inorganic nano-sol to form inorganic nano-sol oligosiloxane hybrid solution. According to the present invention, an inorganic nano-sol prepared from an inorganic precursor in a polar solvent including water and a water-dispersed inorganic nano-sol of which particle size is controllable are surface treated, and then, oligosiloxane is prepared to form an inorganic nano-sol oligosiloxane hybrid solution by additionally mixing organic silane with a solution in which a surface-treated inorganic nano-sol is dispersed and making the organic silane react with the solution without a substitution process of the organic solvent, thus an inorganic nano-sol oligosiloxane hybrid packaging material having a high particle packing efficiency without accompanying shrinkage during a reaction is manufactured directly through performing drying and hardening without a substitution process of the organic solvent, so that there is an advantage in that the method is applicable to insulation and corrosion prevention of an energy device exposed to an electrolyte.
