Study of polypropylene surface modification by air dielectric barrier discharge operated at two different frequencies
(2012-10-18)
In this work, air dielectric barrier discharge (DBD) operating at the line frequency (60 Hz) or at frequency of 17 kHz was used to improve the wetting properties of polypropylene (PP). The changes in the surface hydrophilicity ...
Reinforcing effect of polypropylene waste strips on compacted lateritic soils
(2020-11-02)
This study evaluated the strength properties of compacted lateritic soils reinforced with polypropylene (PP) waste strips cut from recycled plastic packing with the goal of promoting sustainability through using local ...
Effect of polypropylene fibers on the shear strength–dilation behavior of compacted lateritic soils
(2021-11-01)
The stress–dilatancy relationship for fiber-reinforced soils has been the focus of recent studies. This relationship can be used as a foundation for the development of constitutive models for fiber-reinforced soils. The ...
Thermo-Mechanical Properties of Polypropylene Composites Filled with Recycled Office Waste Paper
(Taylor & Francis Inc, 2022-09-07)
The high production of paper, followed by a more significant concern with environmental and economic issues, has led to greater relevance to paper recycling and its raw uses as composite filler. Composites of polypropylene ...
Shear strength behavior of clayey soil reinforced with polypropylene fibers under drained and undrained conditions
(2021-01-01)
The fundamental mechanisms controlling shear strength and deformability behavior of clay-fiber mixtures have still not been well established, nor the constraints that may affect their performance of shearing under different ...
Synthesis, characterization and properties of poly(propylene-1-octene)/graphite nanosheet nanocomposites obtained by in situ polymerization
(Elsevier, 2015)
Poly(propylene-1-octene)/graphite nanosheet (PPC8/GNS) nanocomposites with different comonomer
and graphite nanosheet (GNS) contents were synthesized by in situ polymerization using metallocene
catalyst. There was a ...
