Several composites based on an L-rich poly(lactic acid) (PLA) and mesoporous Santa Barbara Amorphous-15 (SBA-15) are prepared by their addition through two methods: solution-mixed (solvent casting) or melt-mixed (extrusion). Subsequently, films of all the materials processed compression molding. The nucleating capacity silica PLA crystallization is found to be strongly dependent protocol used f...

Polymer nanocomposites have attracted global attention as a metal replacement for electrical and electronic applications. Graphene nanoplatelets (GNPs) are widely used nanoreinforcement to enhance the functional structural properties of thermoset thermoplastic polymers. In present study, ABS were prepared by reinforcing 3–15 wt.% GNPs in steps 3 wt.%. The neat ABS+GNP nanocomposite specimens me...

A green approach is proposed to achieve a rapid surface functionalization of microcrystalline cellulose (MCC) in 30 min by solvent-free "grafting from" reaction l-lactide through compression molding without the need for an inert atmosphere. sufficient hydrophobization MCC achieved with amount grafted poly(l-lactic acid) (PLLA) oligomers 7 wt % respect MCC. The obtained MCC-g-PLLA subsequently m...

In the present study, novel natural fiber composites, consisting of untreated and alkali(NaOH)-treated chopped henequen fibers polyamide 6 (PA6), were produced by hopper feeding side fiber, upon extrusion process, then an injection molding respectively. The effects alkali treatment route on heat deflection temperature, tensile, flexural, Izod impact properties fiber/PA6 composites investigated....

Epoxy molding compounds have been developed which can simultaneously underfill and overmold the Flip Chip die in a single transfer molding process. Transfer molding is a well-defined industry process; with suitable mold design, these materials can utilize the currently installed capital base. The ability to apply pressure during the molding process can reduce the void rate under the die as well...

The aim of this work was to develop cassava starch biocomposites with varius concentrations grape skin (Gr) and acerola (Ac) residues (0.1, 1.0, 5.0 10.0 wt%) using extrusion injection molding processes. Grape residue had the highest concentration total monomeric anthocyanin (ANC) Ac phenolic content (TPC) sugars. fruit thermal degradation onset temperatures above processing temperature profile...

In situ synchrotron X-ray scattering was used to reveal the transient microstructure of poly(L-lactide) (PLLA)/tungsten disulfide inorganic nanotubes (WS2NTs) nanocomposites. This is formed during blow molding process (“tube expansion”) an extruded polymer tube, important step in manufacturing PLLA-based bioresorbable vascular scaffolds (BVS). A fundamental understanding how such a develops pro...
