  • A simple and economic antistatic agent, (2-methacryloyloxyethyl)acid phosphate (acryl phosphate), was synthesized via the reaction of 2-hydroxyethyl methacrylate with phosphorus pentoxide. The acryl phosphate antistatic agent, synthesized in this study, was introduced into poly(methyl methacrylate) (PMMA) resin via copolymerization with MMA. This antistatic agent provides the PMMA matrix with excellent antistatic properties, including surface resistance and electric charge. A comparison of the present antistatic agent with other commercial agents demonstrated the excellence of not only its electrical, but also its thermal and mechanical properties.

  • Antistatic property and crystallization behavior of antistatic poly(ethylene terephthalate) (PET) were studied by feeding antistatic agents into polycondensation reactor. Glass transition and melting temperature of antistatic PET were decreased by poly(ethylene glycol) (PEG) component of antistatic agent. The crystallization rate of antistatic PET was inhibited by decreasing crystallization temperature. Thermal properties and crystallization behavior was affected POAG content of antistatic agent rather than sodium alkylsulfonate of it. The main antistatic component of antistatic agent was POAG. The main role of sodium alkylsulfonate was increasing melt viscosity of antistatic poly(ethylene terephalate) polymer.

  • Antistatic acrylic resin is made from n-butyl methacrylate, methyl methacrylate, dimethyl amino ethyl methacrylate(DMAEMA), 2-ethyl hexyl methacrylate, hydroxy ethyl methacrylate, 2,2'-azobis iso-butyronitrile by synthesis. To achieve a lowest surface resistance of antistatic acrylic resin was applied to a variety of synthesis processes. The acrylic resin has been determined from the value of surface resistance and -then the antistatic acrylic resin including dimethyl amino ethyl methacrylate of the 10%, 20% and 30% is synthesized. Finally, dimethyl sulfate(DMS) on a variety of weight ratios is added to antistatic acrylic resin. When DMAEMA / DMS weight ratio is 1/1, antistatic acrylic resin isn't haze the lower the surface resistance. Compared to the traditional antistatic agent, all aspects of the physical properties is outstanding.

  • In this study, TPU resin for coating was prepared by varying the mixing ratio of antistatic TPU and recycled TPU to manufacture permanent antistatic materials. The coated yarn was prepared by coating on the nylon yarn, and then the thermal, rheological, mechanical properties and antistatic properties were analyzed. In addition, antistatic properties and durability were confirmed after manufacturing UD fabrics using coated yarns. The mixing ratio of antistatic TPU and recycled TPU was most appropriate at 4:6, and the antistatic property had a surface resistance of 2.20 × 109 Ω and a static charge of 398 V. In the coating process, the coating speed was most appropriate at 0.21 m/s, and the surface resistance of the UD fabric manufactured with the coated yarn manufactured under this condition was 6.80 × 109 Ω and the static charge was 484 V. The UD fabric had a surface resistance of 7.21 × 109 Ω and a static charge of 517 V after washing 10 times, and it was confirmed that the permanent antistatic property was excellent.

  • In this studs, we synthesized durable antistatic agents with acrylic monomers for preventing the electrification of static electricity which is one of defects of polyester fabrics. Also we synthesized quaternary ammonium salts which give antistatic property and crosslinking agents which make antistatic agents adhere to fiber. The treatment of synthesized antistatic agents on polyester fabric carried out at the condition of various concentrations, treatment times and temperatures. The antistatic property, handle characteristics and other properties of treated and untreated polyester fabrics were also investigated.

  • A colorless antistatic agent was prepared for use in antistatic films for liquid crystal displays (LCDs) requiring low surface resistance and high transmittance. Among various lithium-fluoro compounds and quaternary ammonium salts, antistatic materials were selected based on their electrical conductivity, and antistatic agents were prepared to measure the surface resistance. As a result, the material with high conductivity showed a relatively low surface resistance, i.e., relatively good antistatic performance. Based on the antistatic materials selected, the formulation ratio for producing the best antistatic agent was established through the experimental design method and the effects of each factor were analyzed. The higher the use of lithium- fluoro compounds as antistatic materials, the higher the ratio of oligomer use with multi-functional groups, and the smaller the surface resistance. The quaternary ammonium salts increased the antistatic performance of the lithium-fluoro compounds, but the effects of the amount used were not relatively large. After manufacturing the antistatic PET film, the properties of the antistatic film showed low surface resistance values (<109 Ω/sq.), high permeability (>92%), low haze (<0.5%), and high whiteness (L>95). In addition, the antistatic film reliability was found to be excellent by showing a stable surface-resistance change rate of less than 10%, even under high temperature and high humidity conditions.

  • Cotton, P/C and polyester fabrics were laundered and treated with 4 kinds of aftertreating agent(antistatic and softening agents) on marketing. Some treating condition:. which include agent concenteration, treating time and rinsing extent after laundering, were varied. And then the effects of agents with each treating condition-handle value, charged voltage and half-life, and crease recovery etc.-were determined and discussed about their change. The improvement of handle and antistatic properties by treatment were indicated remarkably for cotton fabric and P/C and polyester fabrics respectively. Generally, the handle value of cotton was decreased and then increased again, and the charged voltage and half-life of P/C and polyester fabrics were decreased with increase of concenteration of agents. The effect of antistatic improvement for P/C fabric was larger than polyester fabric at even lower concenteration of agents. The effects were increased with treating time and rinsing extent. In particular, those of short time(1 minute) treatment were very small.

  • The objective of this study was to investigate the changes of the fabric absorbency, stiffness and antistatic property by using a fabric softner at laundering. The samples selected in this study were cotton and polyester fabrics. The cotton fabric was treated with 1/2 times(0.035%), 1 time(0.07%), 3 times(0.21%) and 10 times(0.7%) of the commercially suggested concentration (0.07%) of the fabric softner. And polyester fabric was done at 1 time(0.07%) of that. In order to examine the effect of the fabric by using a fabric softner, the abstraction of a surface active agent and quantitative analysis was performed by using a UV/VIS Spectroscopy and the correlations among the absorbency, stiffness and antistatic property was analyzed. The results obtained from this study were as follows; 1. In the cotton fabric, fabric softner gave the degradation of absorbency, and stiffness improvement was not shown by repeated fabric softner on the cotton fabric. 2. In the polyester fabric, the absorbency increased and the stiffness in creased very slightly. Specially, it is desirable to use fabric softner on the polyester due to improvement of antistatic property.
