Crystallinity and dielectric properties of PEEK, poly(ether ether ketone)

On the dielectric strengths of atmospheric plasma sprayed Al2O3, Y2O3, ZrO2–7% Y2O3 and (Ba,Sr)TiO3 coatings

“…The BST feed stock has both BST and BaTiO 3 as major phases, whereas the coatings show the presence of BST and an amorphous content, which could be inferred from [19]. All samples in our study have fully crystalline structure except BST.…”

Ball milling preparation and characterization of poly (ether ether ketone)/surface modified silica nanocomposite

“…It exhibits a glass transition temperature around 143°C and melts around 340°C [9][10][11]. It is well known that PEEK has a good resistance against most organic solvents except concentrated sulfuric acid (95-98%) and methyl sulfonic acid (CH 3 SO 3 H) [11][12][13].…”

Investigation on the correlation between morphology and electrical breakdown in insulating polymers by using the percolation model

“…However, the roles of crystalline and amorphous parts and their orientation have not been known clearly. For example, the results of some authors' experiments [3,6] that the breakdown strength decreased with the increase of crystallinity seem contradict with other authors' experiments showing that the breakdown strength increased with the material density [4,5]. This difference may be related to the detailed microstructure, such as the crystal size [5] and nano-void concentration distribution [10] etc.…”

“…may lead to the change in electrical breakdown strength [1][2][3][4][5][6][7][8][9][10]. However, the roles of crystalline and amorphous parts and their orientation have not been known clearly.…”
