Polyimide (sometimes abbreviated PI) is a polymer of imide monomers belonging to the class of high performance plastics.With their high heat-resistance, polyimides enjoy diverse applications in roles demanding rugged organic materials, e.g. high temperature fuel cells, displays, and various military roles.A classic polyimide is Kapton, which is produced by condensation of pyromellitic ...
Advanced polyimide materials: Syntheses, physical
The polyimide with dendronized chromophores can achieve high poling efficiency to afford a very large electro-optical (E-O) coefficiency (71 pm/V at 1.3 μm). NLO polyimides containing side chain chromophores were synthesized from functional polyimides and were followed by a Mitsunobu reaction with diol chromophores  ,  ,  , [176 ...
Polystyrene (PS) / ˌ p ɒ l i ˈ s t aɪ r iː n / is a synthetic aromatic hydrocarbon polymer made from the monomer known as styrene. Polystyrene can be solid or foamed. General-purpose polystyrene is clear, hard, and rather brittle. It is an inexpensive resin per unit weight.

Frontiers Safety Issues in Lithium Ion Batteries
As the most widely used energy storage device in consumer electronic and electric vehicle fields, lithium ion battery (LIB) is closely related to our daily lives, on which its safety is of paramount importance. LIB is a typical multidisciplinary product. A tiny single cell is composed of both organic and inorganic materials in multi scale. In addition, its relatively closure property made it ...
