  • The hardening system of polyurethanes has usually caused by air pollution. bad working condition and fire hazard according to using orgarnic solvents. Therefore there have been researched on emulsion, water soluble and colloid-dispersion based water soluble instead of using organic solvents recently. This study synthesized polyurethane dispersing particle by means of mixing precursor and neutralized emulsion method. In the first step, polyurethane was preparated from isophorone diisocyanate and poly (ethylene-adipate) glycol, and got precursor by introducing dimethyl propionic acid as a hydrophilic group. Synthesized polyurethane was bonded to the surface of fiber and crosslinked as a anti-static agent, and then looked for the change of color and softening property.

  • In order to develope anti - static polyester resin which may be employed to dangerous circumstance with high organic vapor content, the effect of anti - static agents on the surface resistance and tensile strength of polyester resin were studied. Three organic anti - static agents and a conductive carbon black were adapted and used separately and together. The effects of anti - static agents, their contents, and synergic effect of anti - static agents were experimentally examined. Surface resistance and tensile strength of the polyester resin were decreased with the content of anti - static agents, and polyester resin with low surface resistance and relatively high tensile strength could be prepared by synergic effect of organic anti - static agent and carbon black.

  • The effects of temperature ana additive on the streaming electrification of insulating oil have been investigated. The streaming current increases below the temperature of $45{\sim}50[^{\circ}C]$ and decreases above that. The inverse phenomenon of steaming current is exhibited as the concentration of anti-static agent increases.

  • This study suggested antistatic material which can increase anti-static properties and mechanical strength by mixing polystyrene for conveying electronic stuffs with metal salt and ester compound as a anti-static agent. We studied about mechanical, thermal and electrical characteristics by changing the contents of MAH of poly(styrene-co-maleic anhydride), compatibilizer. As the result of measuring residue space charge of the blends of HIPS(75)/TPU(25)/poly(styrene-co-maleic anhydride)(MAH weight ratio : 25, 32, 43.5 wt%), we could find small residue charge in the blend which MAH(25 wt%) was added and it showed the highest values in tensile strength. Additionally we found out the material to which compatibilizer was added kept better anti-static properties than one to which compatibilizer was not added. In the event we could confirm that the adding of PS-co-MAH enables two polymers were mixed well when HIPS/TPU was blended and anti-static agent made easier dissipative in the blend.

  • 본 연구에서는 4차 암모늄염의 대전방지 현상을 알아보기 위하여 아크릴기가 있는 2-(dimethyl amino)ethyl methacrylate(DMA)를 알킬화 시켜 대전방지제를 합성하고, 자외선 경화 반응을 통해 대전방지 기능이 지속적으로 유지되게 하였다. 여기에서 얻어진 대전방지제를 PMMA 판에 코팅하여 코팅 도막의 전기저항의 변화를 관찰한 결과, 대전방지제의 함량이 20part 이상으로 높아질 때 표면저항 값이 낮아지는 현상을 볼 수 있었다. 또한 대전방지제의 함량이 10part인 경우, 상대습도가 $20\%$ 증가할 때 저항 값은 $10^2{\Omega}/cm^2$까지 감소하는 결과를 볼 수 있었다.

  • Stable dispersion of antimony-doped tin oxide nano-powder was prepared by wet attrition process by comminuting aggregated ATO nano-powder using the titanate coupling agent as a dispersant to form the chemisorbed layer on the particle surface. The feed solution of the ATO dispersion and PVP was prepared for electro-spun fibers on the glass substrate. The surface resistance of the fibrous ATO film after electrospinning for 30 minutes was in the order of 105 Ω/□, which is sufficient for anti-static coating. The optical transmittance of ATO fibers was confirmed by measuring the visible light transmittance.

  • We conducted investigation on polymeric binders for anti-static coating agent which can maintain stability under the high-voltaic condition. Various polyesters composed of polyethylene glycol (PEG) and polypropylene glycol (PPG) were synthesized and studied in term of the variation in the surface resistance of the film made from coating solution composed of a conductive polymer and these polyesters as a binder. We found that the surface resistance displayed $10^7{\sim}10^8{\Omega}/{\square}$ regardless of chemical composition of binders under the potential of 10 V. Whereas, the surface resistance surged to higher than $2{\times}10^{10}{\Omega}/{\square}$ when 1000 V was applied, rendering it improper for anti-static purpose. When 1,4 butanediol (BD) was incorporated into polyesters ([PEG]/[PPG]/[BD] = 25.0/67.5/7.5), the surface resistance showed $2.8{\times}10^9{\Omega}/{\square}$ under 1000 V, acceptable for anti-static application. These observations may indicate that the hydrophobic nature of BD makes a significant contribution to the surface resistance at a high positive potential.

  • This study was carried out to improve the skin care property of the polyester fabric by finishing with sericin. It was known that skin care function, anti-oxidation, anti-tyrosinase activity and anti-elastase activity can be achieved from sericin finish. But, the moisture regain of the finished fabric was measured simply, because the major cause of the discomfort from polyester fabric has been anounced to be wetness. The effects of various treatment conditions on the properties of the finished fabric were measured, and obtained results were as follows: 1. The moisture regain at 40$^{\circ}C$ 90% RH were increased with the sericin uptake increasing. while it was not significant for the effects on the moisture regain depending on the treatment conditions like the degree of polymerization and treatment concentration of the binder. The moisture release of the fabric having sericin uptake 1%, 2% was faster than non treated fabric. The change of the moisture regain of the finished fabric from 40$^{\circ}C$ 90% RH to room temperature was 4∼5 times higher than that of knitted cotton fabric. 2. The frictional static charge was decreased with the degree of polymerization of the binder increasing. While the sericin uptake and treatment concentration of the binder were not significant. 3. The whiteness value of the fabric was slightly decreased by finishing with sericin and binder. In that cases, W values of the finished fabrics were above 90 while that depending on the degree of polymerization of the binder was not significant. 4. The major cause of the yellowness of the finished fabric was proved to be catalyst. The yellowness of the finished fabric with sulfur containing catalyst was lower than that with amine group containing catalyst. 5. The effects of the treatment concentrations of the cross-linking agent, catalyst and drying time on the wash durability were not significant.
