مرجع پلیمر در بازار ایران: رزین اپوکسی از خانواده رزین های دو جزئی است که شامل پایه رزینی و هاردنر است. این دو جزء باید به نسبت مشخص و بنا بر فرمولاسیون و کاربرد آن با یکدیگر ترکیب شوند و پس از آن روی سطح یا قالب دل خواه استفاده شود. کاربرد رزین اپوکسی استفاده از رزین‌های اپوکسی به بیش از ۵۰ سال پیش برمی گردد و امروزه از پرکاربردترین مواد در مصارف مختلف هستند. استفاده از آن‌ها تنها به صنایع پوششی محدود نمی‌شود و در صنایع ...
PolymPart: Interest in high-spin organic materials is driven by opportunities to enable far-reaching fundamental science and develop technologies that integrate light element spin, magnetic, and quantum functionalities. Although extensively studied, the intrinsic instability of these materials complicates synthesis and precludes an understanding of how fundamental properties associated with the nature of the chemical bond and electron pairing in organic materials systems manifest in practical applications. Here, we demonstrate a conjugated polymer semiconductor, based on alternating cyclopentadithiophene and thiadiazoloquinoxaline units, that is a ground-state triplet in its neutral form. Electron paramagnetic resonance and magnetic susceptibility ...
PolymPart: Thesis student Jan Reifenhäuser at the Koblenz University of Applied Sciences explores the uses of 3D printing in creating improved antennas for multiple applications, outlined in ‘Investigation of a Plastic Printed Slotted Waveguide Antenna for Airborne SAR Applications.’ Reifenhäuser’s interest in creating antennae are directly related to a new project at the German Aerospace Center, as they begin working with synthetic aperture radar (SAR) technology in Ka-band—more specifically, the Ka-band PolInSAR system. Due to requirements for excellence in mechanical accuracy, 3D printing was chosen as the manufacturing method with temperature-resistant plastic. The researchers involved in the project created two different antenna prototypes ...
