Determination of Percentage of Hydrophilicity and Hydrophobicity and Surface Free Energy Components at Basal and Edge Surfaces of Talc by Flow Microcalorimetry
ثبت نشده
چکیده
The adhesion between mineral surfaces and organic polymers is important in many industrial products. Examples range from paints to filled plastics and fiber reinforced composites. Talc, for example, is well known to be an important reinforcing filler for polyolefins such as polypropylene (PP) and polyethylene (PE) [1]. Usually, for this application, there is no need to treat the mineral surfaces since the basal planes of talc are naturally hydrophobic thus matching the non-polarity of PP and PE. Nonetheless, it is believed that the interaction between talc and non-polar polyolefins is more favorable as the ratio basal planes/edge or hydrophobic/hydrophilic surfaces of talc increases.

Hydrophobicity Properties of Graphite and Reduced Graphene Oxide of The Polysulfone (PSf) Mixed Matrix Membrane
Hydrophobicity properties of graphite and green synthesized graphene (gsG) from exfoliated graphite/GO towards polymer membrane characteristic and properties at different weight percentage concentrations (1, 2, 3, 4 and 5 wt. %) were investigated. PSf/graphite and PSf/gsG membranes were characterized in term of hydrophobicity, surface bonding, surface roughness and porosity. FTIR peaks revealed...

متن کاملCorrelation between Surface Free Energy Parameters of Solids and Separation Efficiency in Mineral Beneficiation
Knowledge of surface free energies (and its components) between two entities is important. They dictate not only the strength of the interaction, but also control the processes such as the stability of aqueous colloidal suspensions, the dynamics of molecular self-assembly, wetting, spreading, deinking and adhesion (1-4). Many of the mineral processing techniques, e.g. froth flotation, selective...
