In this paper, polyester fibers (PET) were treated with low temperature plasma firstly. Then, these plasma treated PET fibers were coated with polypyrrole (PPy) by pyrrole deposition polymerization to impart conductive property to the fibers. Interfacial shear strength (ISS) between PET fiber and asphalt was measured by single fiber pull out test. XPS and SEM were used to characterize the fibers' surface configuration and analysis the functional groups. The results show that plasma-treatment has a strong effect on the surface morphology, surface elements, electrical property and the ISS. © (2011) Trans Tech Publications, Switzerland.

An active tertiary hydrogen atom containing poly(butyl methacrylate-co-butyl acrylate) was firstly synthesized via suspension polymerization, and then a novel functional resin containing rigid calcium carbonate was prepared by reactive extrusion while poly (butyl methacrylate-co-butyl acrylate), nano-calcium carbonate, hydroxyethyl methacrylate and benzoyl peroxide were used as matrix polymer, filler, reactive monomer and initiator, respectively. The corresponding structure and properties of the prepared resin were characterized by using thermogravimetric analyzer, field emission scanning electron microscope and X-ray diffractometer. The oil absorption of the resin before and after acid treatment and the capability of the resin before and after alkali treatment to absorb cationic blue dye were investigated in detail. The results show that acid treatment can not affect the oil absorption of the resin, and the resin can completely remove oil from water through absorption when circulating absorption time reached 50-60 min; additionally, the composite after alkali treatment for 30 min has good capacity to absorb cationic blue dye in comparison with the untreated ones. © All right reserved.

Native corn starches were acid-treated at 53 °C for hours in HCl aqueous solution. The peak temperature (Tp) and heat of gelatinization (ΔHgel) before and after treatments were determined. The average particle size, TG and viscosity were measured. The results showed that the viscosity of corn starch decreased from 630mPa to 4.6mPa after acid treatment for 6h. The average particle size decreased andΔHgel decreased obviously after acid modification.

Polypyrrole (Ppy)-coated viscose fibers have been prepared by vapor phase and liquid phase pyrrole deposition technique, respectively. Comparative morphological and electrical property analysis was carried out on the viscose fiber prepared with both vapor and liquid phase processes. The result showed the configuration of Ppy coatings and electrical property had a strong relation with the deposition technique. Ppy-coated viscose fiber prepared by vapor phase show a high uniform polypyrrole coatings, fine Ppy granular structure, lower electrical resistance, and good fastness performances to abrasion. © (2011) Trans Tech Publications.

To improve the adhesion between ultrahigh molecular weight polyethylene (UHMWPE) fiber and polymer matrix, pyrrole is oxidatively polymerized on the UHMWPE fiber surface continuously. The micro-composite of polypyrrole (PPy)-coated fiber/epoxy was prepared and the fiber was studied by interfacial shear strength (IFSS) through a single fiber pull-out method. Compared with the UHMWPE fiber as-received, the mean value of IFSS between PPy-coated UHMWPE and epoxy increased from 1.06 MPa to 5.72 MPa. In addition, the surface morphology and structure of PPy-coated UHMWPE fiber were studied by SEM, FT-IR, DSC and DMA. The results showed that PPy-coated UHMWPE fiber surface was observed with some particles attached. Although there is no chemical interaction between PPy and UHMWPE chains, PPy has some interaction with UHMWPE molecular chains according to the results of DMA. The PPy coatings have an effect on the adhesion may be associated with the roughened surface of the fiber and upon intermolecular interaction. © 2011 Elsevier B.V.

The effect of acid modification using 1mol/L HCl on viscosity, thermal properties and mechanical properties of potato starch pastes and starch film were investigated. After acid modification, the surface of starch granules did not show more roughness and viscosity of starch pastes become lower. The results of DSC indicated that acid should act on amorphous region of starch firstly and would act on the crystallization region with the longer treatment time. In the very close viscosity scope, the mechanical properties of starch films were increased obviously after acid modification. © (2011) Trans Tech Publications.

Carbon black/polyester (CB/PET) electrically conductive fibers were prepared by melt spun method. The effect of coupling agent on the percolation threshold concentration and Tg of CB/PET fiber was discussed, and the relationship of CB content with thermal and electrical properties of CB/PET fibers was investigated. The results showed that percolation threshold content and Tg of CB/PET fiber were decreased after CB being treated by coupling agent. And CB content has a strong effect on the properties of CB/PET fiber, i.e. the positive temperature coefficient effect of CB/PET fiber moves to higher temperature with CB content increasing; CB/PET fiber has a strong positive strain coefficient effect when CB content is 11%. ©.

The two deposition polymerization techniques, i.e. vapor phase and liquid phase pyrrole deposition polymerization were applied to Ultra-high-molecular- weight polyethylene (UHMWPE) fiber in this paper. The effect of deposition technique on the surface morphology, mechanical properties, electrical stability and surface roughness of fibers were discussed. The result showed that deposition technique has a strong effect on the properties of UHMWPE fibers. Fibers treated by vapor phase deposition polymerization has much fine and small granular structure, lower resistance, better mechanical property and higher surface roughness value. © (2012) Trans Tech Publications.
