WebA nonwettable polypropylene (PP) surface was modified by an ion-assisted reaction (IAR) to improve its adhesion with a conjugated polymer, polyaniline (PAN). Hydrogen ions with energies ranging from 0.6 to 1 keV were irradiated on the PP surface in an oxygen gas environment. Ion doses were in the range 5 × 10 14 to 1 × 10 17 ions/cm 2.

However, sufficient chain mobility was in favor of the dynamic rearrangement of ion aggregation over the fracture surface that imparted the self-healing behavior. floating charlie christian pickup for archtop
4.9: Polyatomic Ions - Chemistry LibreTexts
A polyatomic ion (also known as a molecular ion) is a covalent bonded set of two or more atoms, or of a metal complex, that can be considered to behave as a single unit and that has a net charge that is not zero. The term molecule may or may not be used to refer to a polyatomic ion, depending on the definition used. The prefix poly- carries the meaning "many" in Greek, but even ions of two ato… WebIon channeling through the poly-Si grains during doping by ion implantation may also lead to direct penetration of dopants into the substrate and/or to doping of gate dielectric. This becomes a source for diffusion. Dopant penetration leads to a reduced oxide charge-to-breakdown Q BD, especially in very short channel transistors. WebA negatively charged polyatomic ion that has one or more oxygen atoms bonded to another element is known as an oxyanion; for e.g. the sulphate, nitrate, and carbonate ions. A … floating charge 意味
