Poly Ethylene

Highly light scattering structures have been generated in a poly(ethylene terephthalate) (PET) film using a CO2 laser. The haze, and in some cases the transparency, of the PET films have been improved by varying the processing parameters of the laser (namely, scanning velocity, laser output power, and spacing between processed tracks). When compared with the unprocessed PET, the haze has improved from an average value of 3.26% to a peak of 55.42%, which equates to an absolute improvement of 52.16% or a 17-fold increase. In addition to the optical properties, the surfaces have been characterised using optical microscopy and mapped with an optical profilometer. Key surface parameters that equate to the amount and structure of surface roughness and features have been analysed. The CO2 laser generates microstructures at high speed, without affecting the bulk properties of the material, and is inherently a chemical-free process making it particularly applicable for use in industry, fitting well with the high-throughput, roll to roll processes associated with the production of flexible organic photovoltaic devices.

In this study, the organic-inorganic composite elastic latex was prepared by using the polymerization process of pre-emulsification semi-continuous combined monomer dropping and investigated for the effect of the manner of the introduction of inorganic component and the amount of silica on the mechanical properties of the polymer film and water absorption. The results show that, when the sol is introduced with emulsion by the physical blending method and TEOS and A-151 are introduced together, the amount of them are respectively 1.5% and 9%, the organic-inorganic composite emulsion can be prepared. Meanwhile, if SiO2is added by the way of TEOS and A-151, the best film properties of organic-inorganic acrylate flexible latex will be obtained .
