Fabrication of biodegraded composite from polypropylene, polypropylene grafted maleic anhydride, and chempedak seed (Artocarpus integer) starch has been conducted. The stages were prepared Cempedak seed, grafting process anhydride on fabrication with a composition ratio PP: PP-g-MA: (9.5:0.5:0.1)g, (9.5:0.5:0.2)g, (9.5:0.5:0.3)g, (9.5:0.5:0.4)g, (9.5:0.5:0.5) g, (10:2)g. composites obtained cha...

The viscoelasticity of several polymers has been determined using dynamic mechanical analysis (DMA). For the same materials the sliding wear in multiple scratching along the same groove has also been determined. The materials studied were polycarbonate (PC), polystyrene (PS), styrene/ acrylonitrile (SAN), Surlyn, polyethersulfone (PES), acrylonitrile/butadiene/styrene (ABS), polypropylene (PP),...

In this study concept of experimental design is successfully applied for the determination of optimum condition to produce PP/SWCNT (Polypropylene/Single wall carbon nanotube) nanocomposite. Central composite design as one of experimental design techniques is employed for the optimization and statistical determination of the significant factors influencing on the tensile modulus and yield stres...

Underwater plasma discharge is used for surface activation of polypropylene nonwoven fabrics with subsequent immobilisation of silver or copper. Plasma generated at atmospheric pressure is preferred as this is a low cost and environmental considerate technique in comparison with other techniques. At the same time, the antibacterial properties of silver and copper are well known. The underwater ...

Mussel-inspired approach was attempted to non-covalently functionalize the surfaces of boron nitride (BN) with self-polymerized dopamine coatings in order to reduce the interfacial thermal barrier and enhance the thermal conductivity of BN-containing composites. Compared to the polypropylene (PP) composites filled with pristine BN at the same filler content, thermal conductivity was much higher...

The electrostatic charge on nylon, polypropylene (PP), and polytetrafluoroethylene (PTFE) after rubbing against stainless steel and against each other was examined using a newly developed rubbing device with automated features. It is observed that the charge generated on PTFE and PP increases as the contact force increases, while the charge generated on nylon is not affected by the contact forc...

Long-term hygroscopic thickness swelling rate of polypropylene (PP) composites filled with thermally treated wood flour was investigated. The beech chips were heat at 120 °C, 150 °C or 180 for 30 min using saturated steam in a digester. based on PP, (BF), and coupling agents (PP-g-MA) made by melt compounding injection molding. weight ratio BF to PP controlled 50/47 all blends. amount agent fix...

Bacterial biofilms are associated with numerous infections and problems in the health care and food industries. The aim of this study was to evaluate the bactericidal effect of an atmospheric pressure plasma (APP) jet on Escherichia coli O157:H7, Listeria monocytogenes, and Salmonella Typhimurium biofilm formation on collagen casing (CC), polypropylene (PP) and polyethylene terephthalate (PET),...

This research work presents an understanding of structure-property relationship in uniaxially oriented multilayer polypropylene (PP) film/foams. Multilayer PP film/foams having 16 layers have been produced by using a unique coextrusion and multiplication technique. A post-uniaxial drawing process at a certain temperature has been carried out to orient the multilayer film/foams in extrusion dire...
