We describe the formation of amphiphilic polymeric assemblies via a three-step functionalization process applied to polypropylene (PP) nonwovens and to reference hydrophobic self-assembled n-octadecyltrichlorosilane (ODTS) monolayer surfaces. In the first step, denatured proteins (lysozyme or fibrinogen) are adsorbed onto the hydrophobic PP or the ODTS surfaces, followed by cross-linking with g...

In this work, a series of polypropylene/polyvinyl butyral (PP/PVB) blends were prepared by melt-blending process, at PVB loadings 3 wt%, 10 wt%, and 30 wt%. The effects of PVB on crystallization behavior of PP were investigated by differential scanning calorimetry (DSC), and polarized optical microscopy (POM). The isothermal crystallization kinetics were analyzed by Avrami equations. It was fou...

In this study, eight binary blends of polypropylene (PP)/ poly [styrene-b-(ethylene-co butylene)-b-styrene] tri-block copolymer (SEBS) and polypropylene (PP)/ polycarbonate (PC) were produced at different composition through twin screw extruder. The composition of the minor phases was changed to correlate the morphology and mechanical properties of binary blends (PP/PC and PP/SEBS) through ther...

PP/sugarcane bagasse fiber composites were prepared by injection molding from two fractions of fibers with different particle characteristics. The mechanical properties the characterized tensile and impact measurements, while local deformation processes acoustic emission testing microscopy. determination dimensions after processing showed that considerable attrition takes place during melt in b...

Szent Gy~rgyi (1-3) discovered that ATP 1 produces a strong contraction in muscle fibers which have been preserved in glycerol. Later Bozler (4-7) found that such fibers, which originally are in rigor, can be transformed into a state closely resembling normal relaxation by physiological concentrations of ATP. The fibers then are very extensible and plastic, and give a strong contraction on addi...

This study explores the hybridizing effect of mechano-chemical activated fly-ash (FA) in polypropylene (PP) composites reinforced with sisal fibers. Activation and resistance against agglomeration FA has been achieved by modifying it 2, 4, 6 wt.% cetyltrimethylammonium bromide (C-tab). activation C-tab particle size reduction to nano-level (< 1 µm) have appropriately a planetary ball milling sa...

Scoria aggregate concrete (SAC) as new green material has been gradually used in some construction projects for its lightweight and high strength, which can reduce the environmental impact of materials. In this paper, residual mechanical properties intact compressive stress-strain relationships polypropylene (PP) fiber-reinforced after high-temperature exposure at 20, 200, 400, 600, 800 °C were...

The functionalizing of a fiber surface by chemical may alter the physical and biological properties fiber. functionalization polypropylene (PP) selected monomers (1) acrylic acid (AA), (2) 2-hydroxyethyl methacrylate (HEMA), (3) 2-dimethyl amino ethyl (DMAEMA), (4) methyl acrylate (MA) studied using two different ultraviolet (UV) irradiation techniques, simultaneous UV (SUVF) pre-UV (PUV).
