Susceptibility to scratch surface damage of wollastonite- and talc-containing polypropylene micrometric composites

Polymer micro and nanocomposites: Structure, interactions, properties

“…A large variety of materials used, or at least experimented as fillers in composites. Besides CaCO 3 and carbon black (see Table 1) a large number of other materials like mica [44,62], short [63,64] and long glass fibers [65,66], glass beads [67][68][69][70][71][72], sepiolite [24][25][26][27][28], magnesium and aluminum hydroxide [73][74][75], wood flour and cellulose [19][20][21][22][23][76][77][78], wollastonite [79,80], gypsum [81,82], clay [62], metal powders (aluminum, iron, nickel) [83,84], steel fibers [85], silicium carbide [84], phenolic microspheres [45] and diverse flame retardants [46] are also mentioned as potential fillers or reinforcements. The chemical variety of the fillers is obvious and this often leads also to differences in particle characteristics.…”

The determining role of calcium carbonate on surface deformation during scratching of calcium carbonate-reinforced polyethylene composites

“…Primary among those are wollastonite [16,17,22,24,[31][32][33][34], talc [31][32][33][34], and clay [29,35]. While significant improvement in scratch resistance was observed with these minerals, they, however, experienced a significant loss in ductility and toughness in relation to their neat counterparts.…”

High molecular weight polypropylene nanospheres: Synthesis and characterization

“…Infrared spectroscopy studies of macro PP and nano PP indicate that both polymers have same chemical structure and chemical bonding. 4. XRD studies reveal that the nanopolymer is more crystalline in nature.…”

“…Polypropylene (PP) is of particular interest because it has been extensively studied in macroscale and is one of the most essential polymers among the commodity thermoplastic materials. Special interest in PP nanospherical particles stems for their potential application in the areas of composite, [2][3][4] biotechnology, 5,6 powder technology, 7 optoelectronics, 8 catalytic support for bioreactor and for waste water treatment, 9,10 electrostatic enhancement application, 11,12 surface and coating technology, 13 etc. For instance, polymer particles with functionalized surfaces could add in the fabrication of nanoscale devices, smart sensing, 14 electrical, 15 and fluorescent 16 properties.…”
