    Abstract: An electrolyte membrane includes a cross-linked reaction product of a benzoxazine monomer and a cross-linkable compound. The electrolyte membrane is impregnated with 300 to 600 parts by weight of phosphoric acid based on 100 parts by weight of the electrolyte membrane, and has a yield strain 0.5% or less, and a yield stress 0.3 MPa or less. The cross-linked material has a strong acid trapping ability with respect to the benzoxazine compound and excellent mechanical properties due to a cross-linkage. Also, the solubility of the cross-linked material in polyphosphoric acid is low, thereby showing excellent chemical stability. Accordingly, when the cross-linked material is used, an electrolyte membrane having an excellent liquid supplementing ability and excellent mechanical and chemical stability at a high temperature can be obtained. The cross-linked material can be obtained by a simple polymerization process by combining a benzoxazine monomer and a crosslinkable compound and by using heat instead of using a polymerization initiator or a cross-linking agent.

    Abstract: Disclosed herein is an image photographing device capable of being auto-focused while moving a lens barrel in an optical axis direction. The image photographing device includes: a lens barrel having at least one lens; a housing receiving the lens barrel therein so that the lens barrel moves in an optical axis direction; and an impact reducing unit elastically supporting the lens barrel in the case in which the lens barrel deviates from a set movement range, thereby primarily damping the lens barrel before the lens barrel deviates from the movement range to collide with other components positioned at an outer side of the lens barrel.
