| Claims ISSA Process, Step by step Components: -Polypropilene that acts as a base -Thermochromic dyes (in the color of your choice). -Polypyrrole denatured. -Bicarbonate to balance the Ph. Proportional amount for the production of 55g of ISSA . Step 1 : Within a indirect heating m edium of the substance in water bath at 90°C, place 36g of polypropilene to melt and combine till it gets completely mixed. Step 2: Once it got completely mixed and with a temperature of 70°C you may remove it from the heat and add 5 grains of the thermochromic dye of the color of your choice and stir. (See image 1.3) Step 3: Add 8g of sodium bicarbonate, stir it,till it gets completely mixed. Step4: Add 23g of polypyrrole denatured and mix ti ll it gets on a cooling phase. Step 5 : Spread the liquid in a tempered glass and expand till it gets a recommendable thickness of 3mm. Step 6: Let it cool down for 2 hours. Step 7: Connect a 9v battery to an electrical switch with a direct cable in order to be connected to any part; of the final material, once you activate the sw itch the change color may occur to the color of the thermochromic dyes, with only one voltage shock, if you want the material to recover its originial color, repeat the switch process.

The thermochromics thermoplastics are materials that can change by temperature, they change through the
incorporation of thermochromics pigments. Exist a differents types of thermochromics materials: organic, inorganic, polymer and gel compounds.
In fact, "thermoplastics" is an adjective used to to refer about the characterization of those polymers which can respond to temperature through it s capacity of elasticity in with lets to deform and get back into its original shape.
In 1954 in Germany, G, Natta and K. Ziegler managed to control the tactility of polypropylene, these experiments made the polypropylene usable today with others plastics for their properties, Polypropylene is a though and flexible plastic that can be bent and subjected to high temperatures.
Today we know about plastics that can transmit electricity: conductive polymers.
The first Conductive polymer was synthesized in 1977 and they were used in batteries in 1981.
In 2000 Alan Heeger, Alan MacDiarmia and Hideki Shirakawa received the Nobel Prize of chemistry by the
development of the semi conductive physics.
The technological development around conductive polymers made its properties were exploted for so many uses in the electronics industry, not only for their conductive properties also by its flexibility, one of the most used in the industry is the polypyrroie, this one can usually be found in the rechargeable batteries.
In the world are produced around 40 million tons of polypropylene and 28.47 millions of polypyrroie, this amount allows us to further leverage its properties under demand.
Based on individual technological development and investigation around materials, we managed to make a new polymer that can change its color and maintain the malleability and strenght together with the conduction properties from the thermochromics and conductive polymers, in order to taking it to an industrial level.
The replicahility of the material is posibie thanks to the mass-production applied to the most common polymers/ plastics. In the world are produced around 40 million tons of polypropylene and 28.47 millions of polypyrroie yearly, common used in rechargable batteries, therefore the production can increase by demand
The process of heating and synthesized is posibie with the implementation of boilers, a common extrusion line and mix, and a drying pavements covered with tempered glass.
In a specific production for any future use, the implementation of molds will be required.. Possible Industrial Application
Proved applications: The material has been proved as a textile because of it's properties of elasticity and strenght in addition of the value added that results in a ecological textile which doesn't contaminate and its tiiendiv with the user,
