“…However, the stiffness and weight of the materials impose limitations for large-scale implementation. Textile-structured polymer materials, such as polyester (Mejía et al, 2010), cellulose acetate (Coronado et al, 2008), cotton textiles (Yuranova et al, 2006), and wool-polyamide (Bozzi et al, 2005), have also been studied in recent years for their low cost, flexibility and large surface area. Polyester, commonly referring to polyethylene terephthalate (PET), is one of the most stable and widely used artificial fabrics in the industry.…”

Heterogeneous photocatalytic oxidation (PCO) has shown great potential for indoor air purification of gaseous pollutants. Research attention has been drawn to the synthesis of new functional photocatalysts, as well as to kinetic studies of the influences of various reaction parameters, e.g., relative humidity. Nevertheless, when applied for practical use, the coating method and coating stability of are also important factors that will directly affect the removal efficiency. In the present study, a simple and economical spray coating method was developed to effectively immobilize TiO 2 nanoparticles onto a polyester fiber filter at low temperature. Colloidal silica was added as a binder in the coating suspension. PCO efficiency evaluation of the coating was carried out using gaseous formaldehyde. The results indicate that the formaldehyde removal rate is associated with the amount of binder added. The highest removal rate was achieved for a coating with the TiO 2 to binder (SiO 2 equivalent) mass ratio of 1:1, with the results supported by XRF, SEM, FTIR and BET analyses. As compared to the conventional dip coating method, the spray-coated sample showed much higher PCO efficiency and stability, which may be mainly attributed to the more uniform dispersion of the catalyst and the stronger binding formed during high pressure spray coating. This coating method has great potential for large-scale applications of immobilized photocatalyst for indoor air purification.

Abstract-The aim of this research was to study the effect of the coupling agents, HI-LUBE TM and Licowax TM OP on, rheology properties, thermal properties, mechanical properties and self-cleaning properties of PBT-nanowire ZnO composite fibers. Variation of the nanowire ZnO contents in the PBT composite fibers resulted in self-cleaning properties of the fibers. With increase in the amount of nanowire ZnO in PBT composite fibers, the self-cleaning properties of the PBT composite fibers gradually increased. The ZnO/PBT composite fibers in presents of ZnO 5wt% showed the best results of self-cleaning less than 30 hours of the sunlight which the similar results were found less than 54 hours of 20 watts of UV radiation. Both coupling agents were not affected the self-cleaning properties of the fiber. The Melt Flow Index of the Licowax TM OP-series sample (L-series) slightly higher than HI-LUBE TM -series sample (E-series) due to the lubricant additive agent increasing the process ability. SEM micrographs showed the fracture surface of the nanowire ZnO composite fibers at different ratios. The mechanical properties of the ZnO/PBT composite fibers results provide further evident to proof that this composite fibers was able to make textile products. Moreover, the HI-LUBE TM additive was presented the well mixing between nanowire-ZnO and PBT due to HI-LUBE TM is a coupling agent and lubricant while Licowax TM OP is a lubricant.

INTRODUCTIONMany attentions have been focused on the polymer-inorganic nanocomposite materials (PINCs). The use of inorganic nanoparticles into the polymer matrix can provide high-performance novel materials that find applications in many fields such as fuel cell, flammability resistance, biomedical, semiconductor, polymer blend compatibilization, textile [1], [2]. However the retention of homogeneous dispersion of nanosize particle in the preparation process of nanocomposites is very difficult because of strong tendency for nanoparticles to agglomerate. To prevent the formation of agglomerated nanoparticles in [6]. It is know that coupling agents such as Silane and polypropylene grafted maleic anhydride are an effective way to improve its dispersibility in polymer matrix as well, and hence ameliorate the polymer matrix, thus enhancing the properties of the resulting composites.Poly(butylene terephthalate) (PBT) is one of the most widely used in automotive, electric, consumer application and textile industry. Beside, PBT also enhances the comprehensive properties of semicrystalline engineering thermoplastic including a high rate of crystallization, good solvent resistance, thermal stability, and excellent processing properties and hence finds its applications in despite its exquisite properties; PBT is very often modified with other polymers and particulate fillers [7].Nano zinc oxide (nano-ZnO) is well-known environmentally friendly and multifunctional inorganic fillers which exhibits l...

Abstract. This research aims to study the effects of the TiO2 in PBT composite fibers on the thermal properties, mechanical properties and photocatalytic properties of the polymer composite. The results showed that the tensile strength of the TiO2/PBT fibers decreased with increasing in the content of TiO2 in polymer matrix. The content of TiO2 in composite fibers did not affect the thermal properties of the fibers but the %crystalline of the composite fibers were increased with content of TiO2 in the composite fibers. The SEM images demonstrated that the TiO2 were well dispersed in the composite fibers. Moreover, some aggregation of the TiO2 in the composite fibers was found at high content of TiO2. The photocatalytic characteristic of the composite fiber was studied thought out self-cleaning properties. The presents of the content of TiO2 in the PBT fibers significantly showed the improving of the selfcleaning properties under UV-A radiation. The TiO2/PBT fibers in the presents of TiO2 10wt% showed the best results of self-cleaning under 168 hours of UV radiation.
