Polymers Polymer : Materials are made up of many (poly) identical chemical units (mers) that are joined together to construct giant molecules. Learn about elastomer and brittle polymer responses, thermoplastics vs. 3 Mechanical Properties 4. thermosets, stress and strain rates, and factors affecting melting and glass transition This document discusses the relationship between polymer structure and properties such as solubility, glass transition temperature, thermal stability, and tensile strength. al. 1 Introduction: The unbeatable combination of such characteristics as ease of fabrication, low cost, light weight, and excellent insulation properties have made plastics one of the most desirable materials for electrical applications. The yield strength of the plastic polymer is the corresponding stress where the elastic region (linear portion of the curve) ends (Fig. Polymers are classified based on their structure and production method. By Fennema 3 What is Rheology? Study of flow and deformation behavior of materials Examples Liquid Foods Flow of water, ketchup, mayonnaise, salad dressings etc. 1 Introduction 4. Basim Abu-Jdayil 1 Polymer Glass Transition Have you ever left a Mar 10, 2013 · POLYMER CHEMISTRY . * Mechanisms of Deformation—Brittle Chapter 13 Introduction to polymer (edited). Describe examples how polymers are used in everyday life. It begins with an introduction and overview of polymers and their increasing applications. It also discusses vibrational spectroscopy using infrared and Raman spectroscopy. Rheology is important for characterizing polymers and understanding how polymer structure affects processing behavior. It encompasses measurement techniques and factors such as strain history, environmental conditions, and polymer structure that affect the flow behavior of these materials. Additionally, the document addresses the This document provides an overview of polymers including their classification, polymerization processes, characteristics, processing techniques, and applications. txt) or view presentation slides online. Visit www. It then covers the classification of polymers, including their thermal behavior as thermoplastics or thermosets. It covers topics like stress/strain behavior, creep, toughness, reinforcement, and modifiers. It also discusses various rheological Polymers can be naturally found in plants and animals (natural polymers) or can be human-made (synthetic polymers). They can be classified by origin (natural or synthetic), bio-stability (biodegradable or non-biodegradable), and polymerization mode (addition or condensation), among other criteria. Conducting polymers have advantages over traditional Oct 17, 2013 · Definition of Polymers Polymers are materials consisting of very long molecules , made up of hundreds or thousands repeating chemical units (the monomer units), covalently bonded together. It begins by defining polymer science and its importance in drug delivery formulations. 102. 4 Examples of Rheological Properties Viscosity Power law What is a Polymeric Biomaterial? What is a polymer? The word is from Greek roots “poly” meaning many and “meros” meaning parts . It discusses the definition of polymers, types of linking in polymers including linear, branched and cross linked polymers. It defines polymers as large molecules formed from monomers linking together in chains. It begins with an introduction to polymers, noting they are macromolecules composed of repeating structural units or monomers linked together. It explains that metals generally have high heat capacity and thermal conductivity but low thermal expansion. 7 Degradability 4. • Hardening, anisotropy, and annealing in polymers. 8 Electrical Conductivity Slideshow 1178179 by This document discusses polymers and their viscoelastic properties. ISSUES TO ADDRESS What are the tensile properties of polymers and how are they affected by basic microstructural features? Hardening, anisotropy, and annealing in polymers. It explains that solubility decreases with longer branches or crosslinking. Learning Outcomes.
