  Nanometer structure and conductor mechanism of polymer modified by metal ion implantation

  摘要：

  Polyethylene terephthalate (PET) has been modified by Ag, Ti, Cu and Si ion implantation with a dose ranging from I X 10(16) to 2 x 10(17) ions/cm(2) using a metal vapor vacuum arc (MEVVA) source. The electrical properties of PET have been improved by metal ion implantation. The resistivity of implanted PET decreased obviously with an increase in ion dose. The results show that the conductive behavior of a metal ion implanted sample is different from Si-implantation samples. In order to understant the mechanism of electrical conduction, the structures of implanted layer were observed in detail by XRD and TEM. The nano carbon particles were dispersed in implanted PET. The nano metallic particles were built up in metallic ion implanted layers with dose range from 1 x 10(16) to 1 x 10(17) ions/cm(2). The nanometer metal net structure was formed in implanted layer when a dose of 2 x 10(17) ions/cm(2) is reached. Anomalous fractal growths were observed. These surface structure changes revealed conducting mechanism evolution. It is believed that the change would result in an improvement of the conductive properties. The conducting mechanism will be changed with increasing metal ion dose.

  The 1,3-dipolar cycloaddition of nitrile oxides and a nitrone to alkylidencyclopropanes 1–5,used as model for methylenecyclopropanes substituted with aryl group (1), electron-releasing groups (2 and 3) and electron-attracting groups (4 and 5) is reported. The cycloaddition to alkylidenecyclopropanes 1–3 gives prevalently or exclusively adducts bearing the cyclopropane ring on the C4 position of the
