The effects of polytetrafluoroethylene (PTFE), graphite, ultrahigh molecular weight polyethylene (UHMWPE), and their compounds on mechanical and tribological properties of glass-fiber-reinforced polyamide 6 (PA6/GF) were studied. The polymeric materials were blended using twin-screw extruder and subsequently injection molded for test samples. Mechanical properties were investigated in terms of ...

This study is focused on 3D printing of polyamide 6 (PA6), PA6/graphene oxide (PA6/GO) and PA6/glass-fibre-reinforced (PA6/GF) composites. The effect graphene glass-fibre reinforcement 3D-printed PA6 explored for improvement the interfacial bond interlaminar strength in ambient, wet high temperature conditions relating to electric car battery box requirements. influence environmental process pa...

In this study, the microstructural development and its effect on thermal conductivity of polyamide6 (PA6)/polypropylene (PP) blends containing boron nitride (BN) reduced graphene oxide (rGo) as hybrid fillers were investigated. Blend samples prepared using masterbatch method to localize BN rGo in matrix phase (PA6). Dynamic rheological results consistent with selective localization PA6 evidence...

Multi-walled carbon nanotubes (MW-CNT) inside a polyamide-6 (PA6)–MW-CNT composite were visualized by atomic force microscopy (i) in a field-assisted intermittent contact and (ii) in the tunneling (TUNA) mode. Individual buried MW-CNTs were clearly discerned within the PA6 matrix. An average diameter of 33 ± 5 nm of the MW-CNTs was determined based on field-assisted intermittent contact mode AF...

Camphor sulfonic acid (CSA)-doped polyamide 6/polyaniline (PA6/PANI) composite nanofibers were fabricated using in situ polymerization of aniline under different CSA concentrations (0.02, 0.04, 0.06, 0.08 and 0.10 M) with electrospun PA6 nanofibers as templates. The structural, morphological and ammonia sensing properties of the prepared composite nanofibers were studied using scanning electron...

Pure polyamide 6 (PA6) and polyamide 6/carbon nanotube (PA6/CNT) composite samples with 0.5 weight percent loading of pristine or functionalized CNTs were made using a solution mixing technique. Modification of nanotube surface as a result of chemical functionalization was confirmed through the presence of lattice defects as examined under high-resolution transmission electron microscope and ab...

O resíduo vulcanizado de estireno-butadieno (SBRr) proveniente da indústria calçados foi reaproveitado como modificador impacto compostos à base poliamida 6 (PA6). copolímero SEBS-MA e a argila montmorilonita foram incorporados aditivos compatibilização reforço, respectivamente. Os processados em um misturador interno moldados por injeção. As propriedades reometria torque, resistência ao impact...

A prototype modular single screw extruder fitted with a screw extracting device is used to monitor melting of an immiscible polymer blend (PP/PA6, with different weight ratios) in this popular type of processing equipment. As anticipated, the observed phenomena are much more complex than those involved in extruding PP or PA6, when the well known Maddock/Tadmor mechanism is valid. Consequently a...

BACKGROUND Stromal-Derived Inducing Activity (SDIA) is one of the most efficient methods of generating dopaminergic (DA) neurons from embryonic stem cells (ESC). DA neuron induction can be achieved by co-culturing ESC with the mouse stromal cell lines PA6 or MS5. The molecular nature of this effect, which has been termed "SDIA" is so far unknown. Recently, we found that factors secreted by PA6 ...

Otomotiv, beyaz eşya, savunma sanayi, uçak ve uzay sanayinde kullanılan bazı parçaların yüksek mukavemetli olmasının yanında aynı zamanda tok darbe dayanımlı olması da istenir. Bu çalışmada, ana matris malzeme olarak mühendislik polimerleri sınıfında yer alan poliamit 6 (PA6) polimeri kullanılmıştır. Katkısız PA6 ile ağırlık %5 oranında cam bilya (CB) katkılı (PA6-5CB), %15 elyaf (CE) takviyeli...
