Over the last 20 years,polymers (and other organic materials) have been developed that exhibit electrical and optical properties that were formerly found only in inorganic materials.Polymers have been found that are piezoelectric,conduct electricity electronically,exhibit second-and third-order nonlinear optical behavior,and perform as light-emitting diodes.7.9 Polymers and Plastics - Chemistry LibreTextsOct 03,2013·Tg = 85°C,Tm = 240°C.PVC.This is one of the world's most widely used polymers.By itself it is quite rigid and used in construction materials such as pipes,house siding,flooring.Addition of plasticizers make it soft and flexible for use in upholstery,electrical insulation,shower curtains and waterproof fabrics.Advanced Polymeric Materials for Electronic and Energy Advanced polymeric materials have showed considerable interest over the past few decades due to their tremendous advantageous coming from the combination of conventional polymeric materials and organic conductors [1-3].Different features like mechanical,electrical,and optical properties can be

Chapter 2 Mechanical Properties of Polymeric Materials

The mechanical properties of polymeric materials depend on the type of polymer,molecular structure,molecular weight,crystallinity rate,polymer alloying,chemical additives,type and amount of colorant,impact modifier,fillers,and reinforcements.These properties also depend on the manufacturing process of the polymeric materials,testing methods,test procedures,and reporting of the property values.Chapter 4 Electrical Properties of Polymeric Materials Polymeric materials are now specified in a majority of applications requiring resistance to extreme temperatures,chemicals,moisture,and stress.In electrical/electronic applications,polymeric materials usually serve a selective insulation or signal transmission function,which is frequently combined with a structural purpose.The important properties and characteristics of polymeric materials can be grouped into two basic categories the insulationCited by 12Publish Year 2011Author Hong Gao,Lan Liu,Yuan-fang Luo,De-min Jia,Feng Wang,Kong-hua LiuA Review on the Fabrication of Polymer-Based Polymers as TE materials have attracted a lot of attention recently due to its easy fabrication processes and low material cost [20,21].Their physical and chemical properties can be tuned to the desired properties through simple molecular modifications,which allows for a large range of flexibility in polymer properties [22,23].In addition
