Selective inhibition of paraffin deposition under high flow rate as a function of the crude oil paraffin type and content by fluorescence depolarization: Polypropylene and high-density polyethylene
Article Abstract:
High-density polyethlene (HDPE) and polypropylene (PP) were studied to identify tailor-made materials for walls of pipelines and ducts for crude paraffinic oil that inhibit paraffin depositions. The static and the dynamic interfacial tensions were observed, by traditional contact angle measurements and by fluorescence depolarization of the natural fluorescent probes of the crude oil, flowing at a high rate.

Investigation of plasma-induced photochemical reaction on a polypropylene surface
Article Abstract:
The surface of a polypropylene (PP) film was modified using acetone and acetone/oxygen. The chemical nature and stability of the surface modification was studied by attenuated total reflection Fourier transform infrared (ATR-FTIR) spectroscopy, X-ray photoelectron spectroscopy (XPS), and scanning electron microscopy (SEM).

Novel in situ fabrication of chestnut-like carbon nanotube spheres from polypropylene and nickel formate
Article Abstract:
A study reported a novel in situ approach to mass fabrication of carbon nanotubes. Composites of polypropylene (PP)/organomontmorillonite (OMMT)/nickel formate (NF) are prepared by mixing these components in a Brabender mixer at an elevated temperature.
