Pc material storage modulus Introduction
Polycarbonates (PC) are a group of thermoplastic polymers containing carbonate groups in their chemical structures. Polycarbonates used in engineering are strong, tough materials, and some grades are optically transparent. They are easily worked, molded, and thermoformed.Because of these properties.
Carbonate esters have planar OC(OC)2 cores, which confer rigidity.The unique O=C bond is short (1.173 Å in the depicted example), while the C-O bonds are more ether-like (the bond distances of 1.326 Å for the example.
Polycarbonate is a durable material.Although it has high impact-resistance, it has low scratch-resistance. Therefore, a hard coating is applied to polycarbonate and polycarbonate exterior automotive components. The characteristics of.
Polycarbonates were first discovered in 1898 by , a German scientist working at the .However, after 30 years' laboratory research, this class of materials was abandoned without commercialization. Research resumed in.
DisposalStudies have shown that at temperatures above 70 °C, and high humidity, polycarbonate will hydrolyze to(BPA). After about 30 days at 85 °C/96% RH, surface crystals are formed which for 70% consisted of BPA.
Phosgene routeThe main polycarbonate material is produced by the reaction of(BPA) and COCl2. The overall reaction can be written as follows: The first step of the synthesis involves treatment of bisphenol A.
Electronic componentsPolycarbonate is mainly used for electronic applications that capitalize on its collective safety features. A good electrical insulator with heat-resistant and flame-retardant properties, it is used in products associated with power.
The use of polycarbonate containers for the purpose of food storage is controversial.The basis of this controversy is their hydrolysis (degradation by water, often referred to as leaching) occurring at high temperature, releases : 1/n.The slope of the loading curve, analogous to Young's modulus in a tensile testing experiment, is called the storage modulus, E '. The storage modulus is a measure of how much energy must be put into the sample in order to distort it. The difference between the loading and unloading curves is called the loss modulus, E ".
