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...

Gambas (Luffa acutangula) plants contain a relatively high carbohydrate of 68.2%, whereas its peel contains 38.94% carbohydrates and 20.6% fibers. peels are rarely utilized typically discarded as food waste. Silica can be used filler reinforcement material to improve the physical mechanical properties. This study discussed synthesizing characterizing bioplastics from reinforced by silica using ...

Polymer-layered silicate nanocomposites have generated great interest due to their improved thermal, mechanical and gas barrier properties compared to conventional composites or neat polymers. Since the surface of most polymers is usually hydrophobic and layered silicate nanoparticles are completely hydrophilic, interactions between them are not favourable. Thus, the first step in the direction...

2014 The onset and morphology of various equilibrium emulsion phases for an A and B homopolymer mixture with diblock A-B copolymers as the compatibilizer, is investigated. Attention is focused on the relation between the relative lengths of the blocks and the elastic properties of the interfacial layer which determines the phase behavior. The curvature elastic moduli K and K, as well as the spo...

The objective of this study was to investigate a technique to obtain inorganic nanoparticle impregnated wood fiber reinforcement in the thermoplastic matrix. Inorganic nanoparticulates as a function of void filler and interfacial compatibilizer were generated through the chemically reconstruction method using two different ionic salts (CaCh to Na2C03). The longer reaction time of two ionic salt...

Poly lactic acid (PLLA) is a promising biopolymer, obtained from polymerization of lactic acid that is derived from renewable resources through fermentation. The characteristic brittleness of PLLA is attributed to slow crystallization rates, which results in the formation of the large spherulites. Its glass temperature is relative high, above room temperature and close to 60 °C, and therefore i...

A series of studies were conducted to investigate the effect of LCP inclusion on the processability of short glass fiber reinforced toughened nylon 6,6. The objective was to identify the role of each component phase and obtain composite synergism arising from a multi-component system. It was found that a hybrid composite offered superior processability over the glass fiber reinforced polymers a...

A novel class of polymers called "slide-ring" (SR) materials with slideable junctions were used for high damping composites for the first time. The SR acts as the high damping phase dispersed in the natural rubber (NR) matrix, and epoxidized natural rubber (ENR) acts as the compatibilizer. The morphological, structural, and mechanical properties of the composites were investigated by atomic for...

To improve the performance of polyvinyl chloride (PVC), composites incorporating polyvinyl chloride (PVC), attapulgite nanoparticles (ANPs), and microcrystalline cellulose (MCC) were successfully prepared. The composites had higher vicat softening temperatures (VSTs) and the MCC had a great influence on mechanical properties of the composites. When MCC was added from 0 to 5 per hundred parts of...

Polymer nanocomposites are new classes of composite materials derived from nanoparticles with at least one dimension in the nanometric range. Polypropylene nanocomposites have attracted a considerable interest due to its most widely used and fastest growing classes of thermoplastic polymer with low cost and low density. However, a problem associated with polypropylene is its dyeability. There h...
