Synthesis, Characterization, and Thermal Properties of Bridged Polysilsesquioxanes–Molecular Nanocomposites
1. INTRODUCTION Bridged polysilsesquioxanes(PSSQ) are a family of hybrid organic inorganic materials prepared by sol-gel technology of monomers that contain a variable organic bridging group and two or more trifunctional silyl groups【1-5】. Silsesquioxanes possess high thermal stability and superior mechanical properties and electrical properties. In this study, three types of bridged PSSQ were ...
متن کاملSynthesis, Characterization and Photocatalytic Properties of MnTiO3-Zeolite-Y Nanocomposites
MnTiO3-Zeolite-Y nanocomposites were synthesized with 5-10-20% (w/w) of MnTiO3 by stearic acid gel method. Then, the gels were calcined at 900 °C for 4 hours and the resulted spectra were investigated at 20% (w/w) concentration. Also, the presence of rhombohedral phase of MnTiO3 in Zeolite-Y matrix was confirmed by XRD, SEM, EDX and BET. The VSM results showed t...
متن کاملCharacterization of Nanocomposites by Thermal Analysis
In materials research, the development of polymer nanocomposites (PN) is rapidly emerging as a multidisciplinary research field with results that could broaden the applications of polymers to many different industries. PN are polymer matrices (thermoplastics, thermosets or elastomers) that have been reinforced with small quantities of nano-sized particles, preferably characterized by high aspec...
متن کاملinvestigation of thermal comfort properties of woven sport fabric using blend of estabragh fibers
امروزه لباس در نظر ورزشکاران و کسانی که برای اوقات فراغت خود و یا برای رسیدن به اندامی متعادل، ورزش می کنند؛ بسیار با اهمیت است. احساس مطلوب از لباس در زمره خصوصیات راحتی پوشش می باشد. خصوصیات انتقال رطوبت لباس، در ارزیابی راحتی حسی و حرارتی منسوجات تولید شده از آن ها بسیار مهم است. هدف از این تحقیق، معرفی پارچه جدید است که متشکل از الیاف استبرق با خواص منحصر به فرد می باشد. استبرق لیف طبیعی تو...
Octasilsesquioxane reinforced DGEBA and TGDDM epoxy nanocomposites: Characterization of Thermal, Dielectric and Morphological properties
The octa-functionalized polyhedral oligomeric silsesquioxane (POSS) containing nanocomposites of epoxy resin are prepared via in situ co-polymerization of epoxy resins with 4,4’-diaminodiphenylsulfone (DDS) in the presence of octaaminophenyl silsesquioxane (OAPS). Two of the most common, technologically relevant epoxy resins, diglycidyl ether of bisphenol-A (DGEBA) and tetraglycidyl diamino dip...
