Description
Polymer based nanocomposites have attracted a lot of attention in the semiconductor industry for many different applications such as sensors, solar cells, lighting and display, to name a few. Polyethylene Terephthalate (PET), an insulating polymer with electrical conductivity of up to 10-15 S.m-1 shows desirable electrical characteristics after ion implantation. In this work, 100keV Ti+ and Ar+ ions were cryogenically implanted into Polyethylene Terephthalate (PET) foils of about 130 µm thickness. The PET samples were then characterized using Fourier-Transform Infrared (FTIR) Spectroscopy to determine the chemical and molecular structure of implanted species. UV-Vis was carried out to determine the electronic band gap and XRD to determine the crystallinity. The electrical properties of the implanted PET were investigated through current-voltage (I-V) measurements. This presentation describes and explains results of the characterisation measurements with a view to establishing structure-property relationships of the cryogenically implanted PET. The ultimate goal of this study is develop polymer based nanocomposites for applications in nuclear and solar radiation sensor devices.
