WebSemi-Crystalline Polymers with Examples. Examples of crystalline polymers are, but not limited to: Polyethylene (PE), Polypropylene (PP), and Polybutylene terephthalate (PBT) Polyethelyne (PE) is an element we use on a daily basis (and arguably the ruin of our environment). PE is the most common plastic. WebCrystalline solids have a very high degree of order in a periodic atomic arrangement. Practically all metals and many other minerals, such as common table salt (sodium chloride), belong to this class. Noncrystalline …

WebApr 9, 2024 · Materials that exhibit their mesophases at room temperature and maintain their liquid crystalline characteristics over a large temperature range are desirable for practical applications. Utilizing mixtures is one approach to this because, in these cases, the mesophase–isotropic line is linearly or slightly improved with composition [ 61 , 62 ... WebPerhaps the most famous example is that of the polymorphs of carbon: graphite and diamond. β-HgS precipitates as a black solid when Hg(II) salts are treated with H 2 S . …
WebSome examples of amorphous solids are glass, rubber, pitch, many plastic etc. Quartz is an example of a crystalline solid which has regular order of the arrangement of SiO 4 tetrahedra. If quartz is melted and the melt is cooled rapidly enough to avoid crystallization an amorphous solid called glass is obtained. Amorphous Solids are Isotropic WebPolymers can exist as both crystalline and amorphous solids. In fact, most polymers are semicrystalline, which means that they contain a mixture of crystalline and amorphous regions. In this video, we'll see different …
WebTwo kinds of ordering are found in crystalline alloys. Most alloys at low temperature are binary crystals with perfect ordering. An example is the alloy of copper and zinc. Copper is fcc, whereas zinc is hcp. A 50-percent-zinc–50-percent-copper alloy has a different structure—β-brass.
