Multi-wall carbon nanotubes (MWNTs) filled polypropylene (PP) nanocomposites were prepared through diluting a PP/MWNT masterbatch in PP matrix by melt compounding with twin screw extruder.Polypropylene grafted maleic anhydride (PP-g-MA) was used to promote the dispersion.The effect of PP-g-MA addition on rheological, mechanical and morphological properties assessed for different MWNTs loadings.Scanning electron microscopy (SEM) has shown that are distributed reasonably uniformly.A better...
Halloysites/polypropylene nanocomposites with different nanotubes contents were prepared by diluting a masterbatch containing 30 wt.% halloysites polypropylene (PP).Unmodified (HNTs) and quaternary ammonium salt treated (QM-HNTs) halloysite used.Both degree of crystallinity crystallization temperature increase upon addition into PP, thus indicating potential nucleation effect induced the nanotubes.An homogeneous distribution dispersion was observed throughout PP matrix, slightly better in...
Abstract Poly(lactic acid) (PLA)/halloysite nanotubes (HNT) nanocomposites were prepared by melt extrusion using a masterbatch dilution process. Effect of addition both unmodified halloysites and quaternary ammonium salt treated (m‐HNT) was investigated at different nanofiller contents. A homogeneous distribution/dispersion in the PLA matrix is obtained for modified within studied composition range. The nucleating effect halloysites, resulting limited increase degree crystallinity, more...
Abstract This paper aims to identify the main parameters that improve flexural properties of long glass fiber/polyamide 66 injection moulded parts. The mould geometry has been chosen so as reproduce some geometrical accidents (e.g. sharp frontal and tangential steps) occurring on industrial moulds. A Taguchi design experiments (DOE) used in order quantify effects processing conditions strength modulus. Polymer melt temperature is parameter acting properties, both flow transverse directions....
The crystallization behavior and the crystalline structure of nylon6-clay nanocomposites are investigated with regard to processing conditions thermal treatment. Microextruded bulk samples as well blown films under concern. often reported nucleating effect clay particles is shown strongly depend on parameters prior solidification step, namely, shear intensity which promotes self-nucleation temperature melt regulates density these unstable nuclei. MMT content influences kinetics via...
Abstract Bio‐based polyamide 11 and natural halloysite nanotubes (HNTs) were used for the preparation of PA‐11/HNT nanocomposites with varying concentrations by melt extrusion using a masterbatch dilution process. The prepared analyzed microstructural changes, transparency, thermal stability, rheological behavior, dielectric, mechanical properties. HNT are well dispersed in PA‐11 matrix studied composition range as shown microscopy spectrophotometry. Interestingly, good dispersion increases...
This paper aims at improving the mechanical behavior of biobased brittle amorphous polylactide (PLA) by extrusion melt-blending with semi-crystalline polyamide 11 (PA11) and addition halloysite nanotubes (HNT).The morphological analysis PLA/PA11/HNT blends shows a strong interface between two polymeric phases due to hydrogen bonding, migration HNTs towards PA11 phase inducing their selective localization in one blend.A 'salami-like' structure is formed revealing HNTs-rich tubular-like...
Abstract Water‐blown bio‐based thermoplastic polyurethane (TPU) formulations were developed to fulfill the requirements of reactive rotational molding/foaming process. They prepared using synthetic and chain extenders. Foams by stirring polyether polyol (macrodiol), extender (diol), surfactant (silicone oil), chemical blowing agent (distilled water), catalyst, diisocyanate. The concentration extender, agent, varied their effects on foaming kinetics, physical, mechanical, morphological...
Based on a previous optimisation of set-up parameters for injection moulding polyamide 6-6 (PA 6-6) reinforced with 40 wt% 10 mm long glass fibre, the aim this paper is to define suitable guidelines further improve mechanical performances PA 6-6/glass fibre thermoplastic (LFT) mouldings.Different solutions have been considered: screw and non-return valve design modification so as adapt them LFT processing, increase initial content (up 50 wt%) length 25 mm) in pellets.Using dedicated...
