Four PA6/graphite (G) composites systems were made. Two in situ polymerisation equivalent mixing strain and two melt extrusion of processing strain. The effective modulus the carbons, room temperature storage at 80 ⁰C evaluated using Dynamic Mechanical thermal Analysis (DMTA). Melt processing, was employed to make PA6/carbon composite over a range loadings Graphite Nano Platelets (GNP) fillers....
Bisphenol A (BPA) is an endocrine-disrupting chemical (EDC) employed in industrial processes that causes adverse effects on the environment and human health. Sensitive inexpensive methods to detect BPA are therefore needed. In this paper, we describe electrochemical biosensor for detecting low levels of using polymeric electrospun nanofibers polyamide 6 (PA6) poly(allylamine hydrochloride) (PAH...
Chitosan (CS) is a natural biopolymer that due to its excellent properties such as biocompatibility and biodegradability suitable for use in many applications. But, dependent on the molecular weight other electrospinning capability of CS very weak. To solve this problem, it recommended blend with second polymer. In work, CS/polyamide-6 (PA6) composite nanofibers were fabricated by technique. Th...
It is a challenge to identify each phase in multi-component polymer system and uniquely determine the interfacial properties between different phases. Using atomic force microscopy nanomechanical mapping (AFM-NM) AFM-based infrared spectroscopy (AFM-IR), we phase, visualize structural developments, blend of three polymers: high-density polyethylene (HDPE), polyamide (PA6) poly(styrene-b-ethylen...
Ultrafine phase change nanofibers based on polyethylene glycol 1000 (PEG1000) as material (PCM) and polyamide 6 (PA6) a supporting were prepared in systematic manner planned by the Design-Expert® software using uniaxial electros-pinning. Research surface methodology (RSM) was carried out to optimize parameters conditions leading minimize fiber diameter. The effect of PEG content, applied voltag...
One of the main limitations high-performance composite materials is failure due to fatigue crack propagation during service. Traditional repair methods can be expensive and time-consuming. For this reason, research in field self-healing composites has considerably increased past decade. At aim, work focused on production a polyamide 6 (PA6) matrix with properties. Cyclic olefinic copolymer (COC...
در این پژوهش نقش نانورس و پرتو الکترونی بر آمیزه hdpe/pa6 (30/70) وزنی با مقدار 3 phr دو نانورس cloisite15a و cloisite30b با روش اختلاط مذاب بررسی گردید. از طرف دیگر آمیزه hdpe/pa6/cloisite30b در دوزهای kgy80-120 پرتودهی شد. آزمون های پراش اشعه ایکس(xrd)، میکروسکوپ الکترونی پویشی(sem)، آزمون کشش (tensile)، گرماوزن سنجی(tga) و آزمون کسر ژلی استفاده شد. تصاویر پراش اشعه ایکس حاکی از آن بود که نان...
هدف این تحقیق، مطالعه تجربی اثر به کارگیری نانوذرات کلسیم کربنات (2 تا 8 درصد وزنی) و الیاف کوتاه کربن (10 درصد وزنی) بر رفتار مکانیکی و شکل شناسی آمیخته pa6/abs (40/60 وزنی) می باشد. از سازگارکننده poe-gr-mah (3 درصد وزنی) در آمیخته pa6/abs استفاده شد. به منظور بهبود چسبندگی الیاف کربن با پلیمر زمینه، عملیات اصلاح سطحی توسط نیتریک اسید 65 درصد روی الیاف کربن انجام شد. آمیخته های مختلف به روش ا...
We studied the composition-dependent miscibility of polyamide 6 and biobased 4,10 (PA6/PA410) blends, as triggered by crystallization driven phase segregation. The blends were prepared extrusion in a wide composition range characterized X-ray diffraction (both in-situ ex-situ SAXS/WAXS), Differential Scanning Calorimetry (DSC), Polarized Light Optical Microscopy (PLOM) during non-isothermal cry...
