Advantages of lamellar thickening

understanding chain fing morphology of semicrystallinea new mechanism for lamellar thickening is proposed to realize that the end of lamellar thickening depends on the crystallinity degree. in other words, it is impossible for lamellae to develop into extendedchain crystals by means of lamellar thickening if crystallinity is to a certain degree.thickening processes of lamellar crystal monolayers of amar 23, 07· at 50°c some small areas in large fc1 crystals spontaneously thicken into ec crystals. at 52°c the spontaneously thickened area further expands so as to inductively thicken the entire fc1 lamella into ec lamella.lamellar thickening growth of an extended chain singlelamellar thickening growth of an extended chain single crystal of polyethylene 1. pointers to a new crystallization mechanism of polymers citation for published version (apa) hikosaka, m., amano, k., rastogi, s., keller, a.
