Abstract ▼ AI-Helper

Cooling function is definitely one of the most desirable attribute of clothing. In spite of the recent progress on phase changing material(PCM) research, the final products with sufficient amount of cooling capability have not yet to be developed in market. A new concept of cooling fabrics has been proposed by applying "Peltier effect" to textile materials. It occurs whenever electrical current flows through two dissimilar conductors; depending on the direction of current flow, the junction of the two conductors is absorbed or released heat. This effect has been tested on P-type and N-type conducting polymers. A P-type conductive polypyrrole coated fabric was synthesized by in-situ polymerization on plain weave PET to make conductive fabrics. And an N-type electrically conductive material was synthesized by treatment of MWNT and polyethyleneimine(PEI). A noticeable amount of temperature difference has been found on the fabrics.

가설 설정

1. General concept of Peltier effect.

제안 방법

This is called the Peltier effect. In this study, to verify the Peltier effect, P-type PPy-PET composite fabrics and N-type MWNT-PEI composite materials were set in the two similar conductive metal plates, and then temperature of two metal plates was measured. Here, the thermal emission and absorption were observed in the upper side and the bottom side of metal because the electron transfers to the hole by an electric current in conductive fabrics.
The purpose of this study was to investigate the prototype active cooling e-textile to flexible, wearable and portable using PPy fiber composite to be synthesized by chemical method^6-8) and MWNT-PEI which was carbon nanotube polymer composites.

대상 데이터

To synthesize N-type MWNT-PEI composite, MWNT(Multiwall carbon nanotube, Iljin nanotech Co Ltd., purity: 95%, diameter: 10-15nm, length: 10-20㎛ without refining and polyethyleneimine (PEI, molecular weight:800) as a polymer were used. In addition, thionyl chloride (SOCl₂), anhydrous THF and chloroform were also used without refining to surface treatment of MWNT and composite synthesis.

이론/모형

In this study, by in-situ polymerization method, the PPy coated P-type PPy-PET composite fabric was developed. After acid and SOCl₂ treatment, MWNT-COCl was transferred in surface of MWNT, and then reacted with PEI.
