To improve the adhesion and wetting between the abaca fibers and matrix, the surface of abaca fabric was modified using plasma polymerization. Different plasma exposure times were conducted to determine the effect of plasma treatment on the properties of the composites. A combination of plasma and other surface modification processes was also investigated to determine whether double treatments could...
Polystyrene (PS) embedded ZnS QDs were prepared via thermolysis of the single source precursor, zinc pyrrolidinedithiocarbamate (ZnPDTC). The in situ growth of 4–6nm QDs was realized by thermal treatment at 375°C and 475°C at different durations, chosen to represent the rubbery and molten state of the polymer matrix. The morphology of the PS/ZnPDTC nanocomposite film was evaluated using AFM. The growth...
In general, plastics are exposed to different degrading agents in every procedure involved in their recovery from waste mixture and from subsequent recycling. In this study, two methods of pre-flotation conditioning were used to determine how these methods affect the general properties of the pre-conditioned PET particles to be recovered from the PET-PVC mixture. The first method comprised the conditioning...
