Download or read book POSS Based Polymers written by Ignazio Blanco and published by MDPI. This book was released on 2019-12-19 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: The combination of functional polymers with inorganic nanostructured compounds has become a major area of research and technological development owing to the remarkable properties and multifunctionalities deriving from their nano and hybrid structures. In this context, polyhedral oligomeric silsesquioxanes (POSSs) have increasing importance and a dominant position with respect to the reinforcement of polymeric materials. Although POSSs were first described in 1946 by Scott, these materials, however, have not immediately been successful if we consider that, starting from 1946 and up to 1995, we find in the literature 85 manuscripts regarding POSSs; which means that less than two papers per year were published over 50 years. Since 1995, we observe an exponential growth of scientific manuscripts concerning POSSs. It is changing from an annual average of 20 manuscripts for the period 1995–2000 to an annual average of about 400 manuscripts, with an increase of 2800%. The introduction of POSSs inorganic nanostructures into polymers gives rise to polymer nanostructured materials (PNMs) with interesting mechanical and physical properties, thus representing a radical alternative to the traditional filled polymers or polymer compositions.

Download or read book Siloxane Based Polymers written by Ignazio Blanco and published by MDPI. This book was released on 2019-07-11 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book, a collection of 12 original contributions and 4 reviews, provides a selection of the most recent advances in the preparation, characterization, and applications of polymeric nanocomposites comprising nanoparticles. The concept of nanoparticle-reinforced polymers came about three decades ago, following the outstanding discovery of fullerenes and carbon nanotubes. One of the main ideas behind this approach is to improve the matrix mechanical performance. The nanoparticles exhibit higher specific surface area, surface energy, and density compared to microparticles and, hence, lower nanofiller concentrations are needed to attain properties comparable to, or even better than, those obtained by conventional microfiller loadings, which facilitates processing and minimizes the increase in composite weight. The addition of nanoparticles into different polymer matrices opens up an important research area in the field of composite materials. Moreover, many different types of inorganic nanoparticles, such as quantum dots, metal oxides, and ceramic and metallic nanoparticles, have been incorporated into polymers for their application in a wide range of fields, ranging from medicine to photovoltaics, packaging, and structural applications.

Download or read book Synthesis of Polyhedral Oligomeric Silsesquioxane poss based Shape Amphiphiles with Two Polymeric Tails of Symmetric Or Asymmetric Compositions written by Zhao Wang and published by . This book was released on 2013 with total page 41 pages. Available in PDF, EPUB and Kindle. Book excerpt: The investigation in the design and synthesis of a new class of well-defined functionalized polyhedral oligomeric silsesquioxane (POSS)-based shape amphiphiles with two polymeric tails of symmetric or asymmetric compositions raised intensive attention recently. Polyhedral oligomeric silsesquioxanes (POSS), regarded arguably as the smallest silicon nanoparticles with cage diameter around 1.0 nm, are promising nanoscopic building blocks for the development of functional materials with hierarchical structures due to their conformational rigidity, shape persistence and diverse peripheral functionalities. The sequential "grafting-from" approach and thiol-ene "click" surface functionalization were employed in the synthesis, which involved thiol-ene mono-functionalization of octavinylPOSS, ring-opening polymerization, atom transfer radical polymerization for "grafting" polymer tails from the POSS-based macro-initiators with controlled molecular weight and low polydispersity, and subsequent thiol-ene "click" surface functionalization. Surprisingly, the vinyl groups on POSS cages were compatible with atom transfer radical polymerization (ATRP) conditions. Thiol-ene "click" chemistry then was applied to give versatile surface functionalizations onto POSS cage. In this way, the polymer chain composition as well as POSS surface chemistry can be tuned separately and efficiently. All the products have been thoroughly characterized by 1H NMR, 13C NMR, FT-IR, size exclusion chromatography and MALDI-TOF mass spectrometry to establish their chemical structures and purities. These POSS-based shape amphiphiles with novel architecture could serve as important model systems in the study of their self-assembling behaviors in bulk, solution, and thin-film states.
