The present invention provides a method for manufacturing a barrier laminate in which barrier materials is directly coated on a paper substrate, by suppressing penetration of barrier materials into paper through the paper surface sizing or coating process and increasing density and smoothness of the paper through the calendering process.

Barrier laminate with excellent barrier properties against moisture and gas and method of manufacturing same

Disclosed are a gas sensor member, a gas sensor using the same, and manufacturing methods thereof, and specifically, a gas sensor member using a one-dimensional porous metal oxide nanotube composite material having a double average pore distribution in which mesopores (0.1 nm to 50 nm) and macropores (50 nm to 300 nm) are simultaneously formed on the surface of a nanotube through decomposition of a spherical polymer sacrificial template and continuous crystallization and diffusion of a metal oxide and a nanoparticle catalyst embedded in an apoferritin is uniformly loaded in the inside and on the outer wall and inner wall of a one-dimensional metal oxide nanotube through a high-temperature heat treatment, a gas sensor using the same, and manufacturing methods thereof are disclosed.

Member for gas sensor, having a metal oxide semiconductor tube wall with micropores and macropores, gas sensor, and method for manufacturing same
