Morphology Development, Structure and Dielectric Properties of Biaxially Oriented Polypropylene

Atomic Force Microscopy Study of Biaxially-Oriented Polypropylene Films

Atomic force microscopy (AFM) uses a very sharply pointed mechanical probe to collect real-space morphological information of solid surfaces. AFM was used to image the surface morphology of a biaxially-oriented polypropylene film. The polymer film is characterized by a nanometer-scale fiber-like network structure, which reflects the drawing process used during the fabrication of the film. Polym...

Effect of morphology and nonbounded interface on dielectric properties of plasma sprayed BaTiO3 Coating

In this research, BaTiO3 thick deposit has been successfully sprayed by air plasma spray. The microstructure and dielectric properties of thick films were investigated by secondary electron microscopy (SEM) and LCR meter respectively. XRD measurement was carried out on plasma sprayed BaTiO3. The results illustrate differences in the crystal structure between plasma sprayed coatings and feed sto...

Modification of Physico-Chemical Properties of Acryl-Coated Polypropylene Foils for Food Packaging by Reactive Particles from Oxygen Plasma

This investigation was focused on the influence of long-living neutral reactive oxygen species on the physico-chemical properties of acryl-coated polypropylene foils for food packaging. Reactive species were formed by passing molecular oxygen through a microwave discharge and leaking it to a processing chamber of a volume of 30 L, which was pumped by a rotary pump. The density of neutral O-atom...

Humidity Dependence of Carbon Dioxide generation during photodegradation of biaxially oriented polypropylene in oxygen Running Title: Humidity dependence of polypropylene photodegradation

Polypropylene /Polystyrene in situ nano reinforced blends fiber: Morphology and properties

Polypropylene / polystyrene blends containing montmorillonite (MMT) were prepared using a twin screw extruder followed by fiber spinning. The melt intercalation of PP and PS alloys was carried out in the presence of a compatibilizer such as maleic anhydride-g-polypropylene (MPP). The crystallization morphology, thermal behaviors and mechanical properties of polypropylene/polystyrene (PP/PS) nan...
