Abstract: A detergent composition may include 10 to 30% by weight of octylphenol ethoxylate, 0.1 to 5% by weight of 2-ethylhexyl alcohol ethoxylate, 0.1 to 5% by weight of ethylene oxide-propylene oxide block copolymer, and the balance of water, based on a total 100% by weight of the composition. The detergent composition may have an excellent virus removal effect in which more than 99.99% of corona virus is removed in 30 seconds. At the same time, provided is a safe detergent composition which has selective properties of not killing various bacteria, and satisfies skin hypoallergenic properties. In addition, the detergent composition is used for various purposes, such as removal of corona virus, removal of oil stains, removal of kitchen dirt, bathroom cleaning, cleaning of mechanical equipment and parts, and removal of oil stains on clothes, and exhibits excellent cleaning ability.

Abstract: An anti-forgery color conversion film includes a photonic crystal structure whose color is converted by an external stimulus such as a breath. The photonic crystal structure includes a first refractive index layer including a first polymer exhibiting a first refractive index; and a second refractive index layer which is alternately laminated with the first refractive index layer and includes a second polymer exhibiting a second refractive index. A consumer who purchases an article including the color conversion film may easily distinguish the authenticity of the article.

Abstract: Provided is a CNT film coated substrate in which CNT is fixed to a substrate using a click reaction, so that a CNT film is uniformly formed with a high density and adhesive strength between the CNT film and the substrate is excellent to have high stability to water or an organic solvent. In the case of the conventional CNT film which was manufactured by spin coating, most of CNT was peeled off in a washing process, but in the case of the CNT film coated substrate according to the present invention, a high-density uniform CNT film coated substrate may be manufactured even after washing, and reproducibility between substrates may be secured.

Abstract: A photonic crystal structure employs such a structure that two layers having different refractive indices are laminated alternately, a polymer including a structure unit derived from a monomer that contains a fluorocarbon group being used for one of the repeated layers such that the photonic crystal structure can respond to humidity and/or organic solvent concentration. Using the photonic crystal structure, it is possible to manufacture a color-conversion photonic crystal sensor having excellent sensitivity and reproduction characteristics.
