Nanostructured Polymer Blends

Chapter 9. Nanostructured Liquid Crystals

By: Goddeti Siva Mohan Reddy,Jaragula Jayaramudu,Kokkarachedu Varaprasad,Rotimi Sadiku,Shanavas Abdul Jailani,Blessing Atim Aderibigbe

Liquid crystals constitute a fascinating class of soft condensed matter characterized by the counterintuitive combination of fluidity and long-range order. Today liquid crystals are best known for their exceptionally successful application in flat panel displays, but they actually exhibit a plethora of unique and attractive properties that offer tremendous potential for fundamental science as well as innovative applications well beyond the realm of displays. This full breadth of the liquid crystalline state of matter is becoming increasingly recognized and numerous new and exciting lines of research are being opened up. In this chapter we look at these exciting developments, focusing primarily on the physics aspects of the new research thrusts, in which thermotropic as well as lyotropic liquid crystals often meet other types of soft matter, such as polymers and colloidal nano- or microparticle dispersions. Because the field is also of interest for researchers who may not have a liquid crystal background we begin with a concise introduction to the liquid crystalline state of matter and the key concepts of the research field. We then discuss nanostructured liquid crystals, followed by applications of nanostructured liquid crystals.

Nanostructured Polymer Blends

Chapter 4. Compatibilization as a Tool for Nanostructure Formation

By: Emmanuel Rotimi Sadiku,Elijah Sobalaje Ogunniran

Great progress has been made in the science and technology of polymer-based nanomaterials over the last decade. Nanostructured polymer systems have attracted much scientific and applied research interest. The last two decades have witnessed significant advances in polymer science and technology generally, but more so for polymer blends. The idea of blending two (or more) polymers, especially immiscible blends, has come with a lot of challenges. Achieving this has brought to the fore the art and science (and engineering) of compatibilization. During the last few decades, the addition of nanoparticles, nanowires, nanotubes, and so on has advanced even further the creation of blends, alloys, and composites with different polymers. In making these blends, intermediaries such as compatibilizers, coupling agents, and other additives are often employed to bring about blends that are satisfactory for the purposes they are intended to serve. Nanostructured polymer blends formation has strongly improved the properties and structural integrities of polymer blends, by employing compatibilization as a tool to achieve such properties and structural integrities of polymer blends. Reinforcing compatibilized polymer blends with nanosize additives has further strengthened the properties and integrities of polymer blends, alloys, and composites.

Nanostructured Polymer Blends

Chapter 8. Significances of Nanostructured Hydrogels for Valuable Applications

By: Kokkarachedu Varaprasad,Emmanuel Rotimi Sadiku,Koduri Ramam,Jaragula Jayaramudu,G. Siva Mohan Reddy

Nanostructured hydrogels represent a unique class of materials that synergizes the advantageous features of hydrogels. Research into nanostructured hydrogels for biomedical applications has seen great progress in recent years owing to their unlimited potential to advance human health. The development of nanotechnology provides opportunities to characterize, manipulate, and organize matter systematically at the nanometer scale. This is because nanostructured systems in general and nanostructured polymer hydrogels in particular have noble advantages as transporters for a wide range of drugs and tissue engineering scaffolds for biomedical (therapeutic) applications. This chapter explains the design and development of different nanostructured hydrogels and their applications in the biomedical field.

Emerging Technologies in Healthcare

By: Matthew N. O. Sadiku,Rotimi A. K. Jaiyesimi,Joyce B. Idehen,Sarhan M. Musa

Health is regarded as one of the global challenges for mankind. Healthcare is a complex system that covers processes of diagnosis, treatment, and prevention of diseases. It constitutes a fundamental pillar of the modern society. Modern healthcare is technological healthcare. Technology is everywhere. This book focuses on twenty-one emerging technologies in the healthcare industry. An emerging technology is one that holds the promise of creating a new economic engine and is trans-industrial. Emerging technological trends are rapidly transforming businesses in general and healthcare in particular in ways that we find hard to imagine. Artificial intelligence (AI), machine learning, robots, blockchain, cloud computing, Internet of things (IoT), and augmented & virtual reality are some of the technologies at the heart of this revolution and are covered in this book. The convergence of these technologies is upon us and will have a huge impact on the patient experience

Nanostructured Polymer Blends

Chapter 3. Theoretical Modeling of Nanostructured Formation in Polymer Blends

By: Oluranti Sadiku-Agboola,Emmanuel Rotimi Sadiku

In recent years there has been a great deal of research on the subject of nanostructured materials. Structure across a range of length scales has been of particular interest. Theoretical modeling of nanostructured formation in polymer blends has gained considerable momentum due to the increased interest in nanostructures, such as nanoparticles, nanotubes, nanopores, and so on. Polymers show universal behavior on long length and time scales. Usually, the size of an ideal polymer is calculated from the freely jointed polymer chain model. The solubility and interaction parameters in nanostructured polymer blends are reviewed. Several computer simulation models for predicting mechanical, electrical, and thermal properties of semicrystalline polymer and nanostructured polymer blends are discussed. Modeling of polymer in solution and the morphological control of nanostructured blends are also reviewed. Further development of nanostructured polymer blends depends on the fundamental understanding of their hierarchical structure and behavior, which requires multiscale modeling and simulation to provide various lengths and time scales. Atomistic-based simulation such as molecular dynamics, Monte Carlo, and molecular mechanics are addressed for the multiscale modeling of nanostructured polymer blends for material design. A mathematical model based on the Cahn–Hilliard nonlinear theory of phase separation is also discussed.
