فرضیه: در سال‌های اخیر، با توجه به موضوع‌های آلودگی زیست‌محیطی، صنایع پلاستیک به مصرف پلاستیک‌های زیست تخریب‌پذیر تشویق شده‌اند. پلی(لاکتیک اسید)، PLA، از شناخته‌شده‌ترین پلیمرهای زیست‌تخریب پذیر با برتری ماهیت زیست‌پایه است. عیب اصلی PLA شکنندگی ذاتی آن بوده که آمیخته‌سازی مناسب‌ترین روش برای غلبه بر آن است. روش‌ها: PLA بسیار چقرمه از کوپلیمر اتیلن-وینی...
Plastics occupy wide place in the applications of automotive, electronics and house goods. Especially reinforced plastics become popular because of their high strength besides their advantages of low weight and easy manufacturability. In this study, mechanical and morphological properties of polypropylene (PP) and high density polyethylene (HDPE) matrix composites reinforced with surface modifi...
Motivated by environment preservation, the increased use of eco-friendly materials such as biodegradable polymers and biopolymers has raised interest researchers polymer industry. In this approach, work aimed to produce bioblends using poly (lactic acid) (PLA) high-density biopolyethylene (BioPE); due low compatibility between these polymers, evaluated additional influence compatibilizing agent...
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...
The control of morphology and interface in poly(styrene-ethylene/butylene-styrene) (SEBS) composites with graphitic fillers is extremely important for the design of piezoresistive sensors for body motion or flexible temperature sensors. The effects of a high amount of graphite (G) and silane coupling agent on the morphology and properties of SEBS composites with anisotropic mechanical propertie...
The mechanical properties and morphology of polypropylene/wood flour (PP/WF) composites with different impact modifiers and maleated polypropylene (MAPP) as a compatibilizer have been studied. Two different ethylene/propylene/diene terpolymers (EPDM) and one maleated styrene-ethylene/butylene-styrene triblock copolymer (SEBS-MA) have been used as impact modifiers in the PP/WF systems. All three...
Polylactic acid (PLA)/styrene-ethylene-butylene-styrene (SEBS) composites were prepared by melt blending. Differential scanning calorimetry (DSC) and wide angle X-ray diffraction (WXRD) were used to characterize PLA and PLA/SEBS composites in terms of their melting behavior and crystallization. Curves from thermal gravimetric analysis (TGA) illustrated that thermostability increased with SEBS c...
