In Situ Study of FePt Nanoparticles‐Induced Morphology Development during Printing of Magnetic Hybrid Diblock Copolymer Films

چکیده
The development of magnetic hybrid films containing diblock copolymers (DBCs) and nanoparticles (NPs) by printing is a highly promising method for scalable low-cost fabrication. During printing, the drying arrangement kinetics DBC NPs play an important role in film formation concerning morphology properties. In this study, evolution ultrahigh molecular weight polystyrene-block-poly(methyl methacrylate) iron platinum (FePt) investigated with grazing-incidence small-angle X-ray scattering (GISAXS) situ during printing. For comparison, pure printed without FePt under same conditions. GISAXS data suggest that addition accelerates solvent evaporation, leading to faster compared film. As almost evaporated, metastable state observed both films. Compared film, such continues longer process because presence NPs, which inhibits reorganization chains. Moreover, investigations field-dependent magnetization temperature-dependent susceptibility indicate superparamagnetic, makes class sensors.

Interference microscopy on thin diblock copolymer films
2014 At equilibrium thin films of symmetric diblock copolymers exhibit a morphology where the lamellar microdomains are oriented parallel to the external surfaces. Interference microscopy has been used to investigate this orientation which results in a quantization of the film thickness. Solution cast films of the symmetric polystyrene/polymethylmethacrylate P(S-b-MMA) diblock copolymers exhibi...

اشعار ریچ، به عنوان اشعاری که همیشه در حال تغییر و دگرگونی هستند، تجسمی از رشد و دگرگونیِ انسان هستد. پایان نامه ی حاضر، با تمرکز بر روی مراحل سیر شعری ریچ از تغییری در دنیا به عکس هایی فوری از یک عروس، سپس به شیرجه به درون کشتی شکسته و در نهایت به صبری عجیب مرا تا اینجا آورده، به بررسی این مراحل در قالب نظر شوالتر در رابطه با سه مرحله ی پیشرفت ادبی زنان یعنی مرحله ی زنانه، زن گرا و زن محور می پ...
15 صفحه اولStability and orientation of lamellae in diblock copolymer films.
The dynamics of microphase separation and the orientation of lamellae in diblock copolymers are investigated in terms of a mean-field model. The formation of lamellar structures and their stable states are explored and it is shown that lamellae are stable not only for the period of the structure corresponding to the minimum of the free energy. The range of wavelengths of stable lamellae is dete...
