Examples
Embodiment 1
[0089] Example 1 - Preparation of Conductive Polymer Composition
[0090] 185.5 grams of a resin of the chlorinated rubber family, such as CLORTEX 20, is added to 344.5 grams of toluene under stirring and stirring is continued to form a solution.
[0091] 227 grams of coated quartz, such as MINATEC 31, was added to the above solution and dispersed with a Cowless mixer at 1200 rpm for 20 minutes.
[0092] After dispersion, 243 g of a sulfonated salt polyaniline solution, such as PANIPOL T, was added, and the dispersion was continued for 10 minutes under the same conditions as above.
[0093] Then put the dispersed product into a TURBOMILL or SUBMILL mill, and use a grindometer to control the particle size of the ground product to obtain a product with a size less than or equal to 2 microns. During the grinding process, the temperature of the product is kept below 50°C.
[0094] The resulting product corresponds to the product mentioned and claimed in this document.
Embodiment 2
[0095] Example 2 - Formation of 1D or 2D Barcodes on Flexible Film Packaging
[0096] A 30-micron thick PET film was printed with a four-color flexographic machine at a speed of 100 m / min to obtain a substrate for production packaging.
[0097] Divide the area to 1cm 2 The conductive composition of Example 1 was applied to the film and spaced evenly across the film so that one of said regions was obtained on each final product.
[0098] After drying, the area is partially deagglomerated with a YAG laser. The resulting barcode has the following characteristics:
[0099] ● Untreated residues
[0100] ● Clear separation between conductive and insulating areas
[0101] ●Good geometric clarity
[0102] ●Conductivity does not change
Embodiment 3
[0103] Example 3 - Overall Background Printing of High Thickness Compositions and Formation of Press Compliant Graphic Symbols
[0104] The electrically conductive composition is uniformly coated at high thickness, ie greater than or equal to 10 micrometers, by means of a roller coater, the entire surface of the substrate consisting of a plastic film is coated and dried in a known manner.
[0105] Using a YAG light source adjustable to a maximum power of 20w, the required is continuously and reversely drawn from the output of the machine by selectively depolymerizing the polyaniline in the composition over those areas that will define the required figure. components. The non-radiating parts will provide the required conductive elements.
[0106] Subsequent processes use the printed areas by means of cutting operations, embossing, transfer printing or film insertion on other plastic substrates or paper substrates.
[0107] The coating step can also be carried out using othe...
