Abstract

In this research two groups of polymer blends have been prepared First group included (High density polyethylene (HDPE): Polypropylene (PP))While the Second group(included Low density polyethylene (LDPE): Polypropylene (PP)) both groups prepared withpolypropylene of (20% and 80%). From the results of tensile test for the prepared blends it has been showed that the optimum blending ratio was (20%LDPE:80%PP and 20%HDPE:80%PP) which thenreinforced with (2, 5 and 8wt%) oftitanium dioxide (TiO2), particle size (0.421μm). Titaniaparticles weremechanically mixed with the polymers prior tomelt mixing for better dispersion.Polymerblend composites were obtained by using single screw extruder. Results showed that mechanical properties increased as titania content increased except elongation.Furthermore the result recorded highest values ofimpact strength and fracture toughness at2%wt TiO2which is 312 Mpa and 572.8Mparespectively,for the polymer blend (20%HDPE: 80%PP) composite and for the polymer blend (20%LDPE: 80%PP) composites the impact strength and fracture toughness are 262.5Mpa and 468 Mpa respectively.The mechanical properties values of 20%HDPE: 80%PP is higher than 20%LDPE: 80%PP polymer blendcomposites. Scanningelectron microscopy (SEM) imagesshowed that there isbonding developed between TiO2 and polymer blends in some regions.

Abstract

In this research, it has been investigated the effect of addition High performance polymer Polytetrafluroethylene (PTFE) on the Ultra-high molecular weight polyethylene (UHMWPE) mechanical and physical properties. It has been prepared three types of blends (95:5, 90:10 and 85:15) of UHMWPE: PTFE by compression method. Stress-Strain curves of polymer blends have been showed that higher ultimate strength and Young modulus were at 95:5 and decreased gradually as wt. % PTFE increased. FTIR inspection has been also accomplished. Finally SEM results showed incompatibility between the polymers with presence of boundaries between the binary polymers phases.

في هذا البحث، قد تم البحث في تأثير أضافة بوليمرعالي الكفاءة وهو بولي اثيلين تترا فلورواثيلين على الخواص الميكانيكية والفيزياوية لبوليمر البولي اثيلين عالي الوزن الجزيئي. تم تحضير ثلاثة انواع من الخلائط بنسب وزنية (95:5, 90:10 85:15 and) لل [ بولي اثيلين تترا فلورواثيلين:بولي اثيلين عالي الوزن الجزيئي [UHMWPE:PTFE]] بواسطة عملية الكبس. ولقد بينت منحنيات الاجهاد-الانفعال للخلائط البوليمرية ان اقصى مقاومة شد ومعامل مرونة كانت عند نسبة 59:9 وتتناقص تدريجيا بزيادة النسبة الوزنية ل PTFE . فحص تحولات فورير بواسطة الاشعة الحمراء (FTIR) تم انجازه ايضا.اخيرا اظهرت صور المجهر الالكتروني الماسح عدم التوافقية بين البوليمرين مع وجود الحدود بين اطوار البوليمرالثنائي.
