Hydrogels – Smart Polymers
Materials which adjust their properties in response to environmental factors such as temperature, pH and ionic strength are rapidly evolving and known as smart materials. Hydrogels are hydrophilic polymers that…
Synthetic Polymer Membranes
Synthetic polymeric membranes show competitive performance in separation industry and are economical too (Fig. 3) . Several books representing extensive research on structure and characterization of synthetic polymeric membranes are…
Liquid Crystal Polymers (LCPs)
Liquid-crystal polymers (LCPs) are a class of aromatic polymers, which are extremely inert. They resist stress cracking in the presence of most chemicals at elevated temperatures including aromatic or halogenated…
SPECIALITY POLYMERS: EXPLORING VERSATILITY IN TYPES, APPLICATIONS AND FUTURE PROSPECTS
INTRODUCTION Speciality Polymers are the class of some HPP, including plastics, polymers, fluids, membranes, smart hydrogels and elastomers that are designed to meet the critical demands of engineers in every…
Advanced Plastics Make Vehicles Efficient, Affordable, & Attractive
When engineering-grade resins were introduced in the 1950s, some auto manufacturers were unfamiliar with the benefits of metal-to-plastic conversion, i.e. how to design plastics into products, and how to manufacture…
Polyampholytes
Polyampholytes represent a special class of polyions that contain both positively and negatively charged units on the same macro moleeule. They can be polymeric zwitterions with positive and negative charges…
Polyelectrolytes
Polyelectrolytes are macromolecules bearing a net charge. Interest in these unique materials spans numerous and diverse areas. They have been investigated because of their essential participation in biological systems, such…
Synthetic Polymers
Synthetic specialty polymers are obtained by the polymerization of monomers synthesized from petroleum or natural gas precursors. Linear or branched macromolecules may be formed from one or many monomers. Distribution…
Diverse Properties and Applications
Many of the most accessible commodity polymers have been studied in detail and their applications have been developed extensively. Interest is now focused on the synthesis and study of specialty…
Origins of Specialty Polymers
Specialty polymers are typically water-soluble polymers that come from three origins, natural, semisynthetic, and synthetic macromolecules. Natural polymers are plant or animal based materials such as cellulose and proteins. Semisynthetic…
