Definitions
- Smart textiles should warm, protect, decorate. But they can do much more.
- intelligent textiles also fulfill other functions such as the ski glove with the integrated chip, which can be recharged again and again for use as a lift pass, or the intelligent one specially developed for Arctic researchers Outdoor suit that uses a radio signal to request help, predict weather and act as a compass in an accident within 30 seconds
- the manufacture of such smart textiles is based solely on the physico-chemical methods used to coat cotton fibers appropriate drug solution applied to the fibers after
- Fiber damage can result, which in turn leads to impairment of mechanical properties and life
- hydroponic culture is well known as a method of culturing plants, it offers advantages over soil culture
- the present invention solves the problems described by choosing a biochemical instead of the physico-chemical approach.
- the invention is based on the use of plant-own processes, shown using the example of cotton plants as biofactory, for the ecological, sustainable production of new composite materials, which are used in the production of intelligent textiles.
- Cotton plants are grown in hydroponic culture, which allows metal oxide nanoparticles (2-5 nm) to be absorbed directly into the plant via the roots. By internal capillary forces, the nanoparticles are transported in the plant and eventually accumulate in the cotton fibers ( Figure 1). It is advantageous that no harmful chemicals or expensive machines are needed.
- the incorporation of nanoparticles overcomes the weak coating stability and thus the leaching of nanoparticles, which leads to permanently active intelligent textiles.
- the type of metal oxide nanoparticles supplied can be varied.
- hydroponics-based cotton farming allows geographic independence, which in contrast to classical plant breeding in humid climates, for example, in Texas, India and Pakistan stands.
- the disadvantage is that the hydroponic cotton growing high running costs caused by long light exposure times (sun or greenhouse) and the cultivation form itself.
- the invention was therefore further based on the object to develop a sustainable solar power operated, automated hydroponic system.
- the growth environment of the cotton plants is used to generate energy itself, whereby the system is designed economically (Figure 2).
- the system consists of a microcontroller (Arduino Uno or Duemillanove with its own program) equipped with a Grove Shield V2, water sensors and air and water pumps (both each 6V).
- This set-up is connected to a two-pin solar panel (2W 10x20cm) and a high voltage battery (LiPo, 10000mAh).
- the controller with shield and sensors is connected to USB port 1 (1A), the pumps to USB port 2 with 2A.
- the system can simultaneously measure the water levels of all compartments in real time and at low level over the pumps, which are also powered by the system.
- the construction consumes less energy than is provided by the sun or greenhouse lamps and can store excess energy in the battery. This results in two advantages:
- the method according to the invention provides a sustainable hydroponic, solar / light-driven automatic system in which the cotton plants grow and reach the cotton formation (FIG. 4) and by the incorporation of microelectronics into intelligent textiles (eg LilyPad) countless applications such.
- B. real-time monitoring of vital parameters (eg, blood pressure, blood sugar) or GPS signals can be used.
- Example 1 In a first step, the inorganic synthesis of nanoparticles and the design of the ligand (organic), which specifically targets the cotton, is carried out. This step involves the characterization of the products (nanoparticles and ligand) by standard methods (eg, transmission electron microscopy, NMR, mass spectrometry, XRD). The nanoparticle synthesis is carried out by an environmentally compatible, scalable method, in which l-3g metal with 10ml of acetic acid and 10ml of distilled water. be mixed to dissolve the metal. After stirring for 30 minutes at 0 ° C, 10 ml of hydrogen peroxide are added dropwise slowly.
- l-3g metal with 10ml of acetic acid and 10ml of distilled water.
- the mixture is left at 0 ° C overnight with gentle stirring.
- the process is completed by evaporating the solvent by means of a rotating vacuum extractor.
- the remaining powder is calcined in an oven at 700 ° C (5 ° C / min) for one hour and then slowly cooled to room temperature.
- Carbodiimide chemistry (EDC / DCC) is used to synthesize the ligand. Cleaning steps are not required.
- the ligand consists of three parts: 1) dopamine as an anchor for the nanoparticles, 2) modified lysine (Fmoc-Boc protected amino groups) as a connector, which also acts as a fluorophore carrier, and 3) a target molecule.
- the surface-activated nanoparticles in a concentration of 0, lmg / ml of the hydroponic nutrient solution was added. After their uptake, the particles migrate towards the seeds via capillary forces and accumulate in the trichomes (seed hairs) (Figure 3).
- the cotton plants remain in hydroponics in the greenhouse at 30 ° C / 25 ° C (day / night), 60% relative humidity and a day / night rhythm of 14/10 at 10-30 klux light intensity.
- the system ( Figure 5) is equipped with a hydroponic plant at its base, allowing all cotton plants to grow in the same way and providing stability to induced stress.
- the system was equipped with an air supply and small access openings (called nanoparticle feed), through which the ligand-functionalized nanoparticles can be introduced into the nutrient solution containers.
- the LED columns serve as a light source for the detection of nanoparticles; they are inexpensive, have a narrow excitation emission wavelength window, extended lifetime (> 25000 h / LED), detection of nanoparticle distribution with the naked eye, possibility of using different wavelengths (blue to light red) for different applications, eg chlorophyll measurements to determine plant activity ,
- the light source (sunlight or incandescent in the case of greenhouse use) supplies energy to the micro-controlled base system.
- This independent system controls both the water level for each compartment and the air supply.
- hydroponic system of the present invention and commercially available cotton fibers (standard culturing techniques)
- the plants are introduced into the hydroponic system.
- Nanoparticles carrying a fluorescent ligand as a marker are added.
- the LED system shows fluorescence phenomena where the nanoparticles are located. The fluorescence can be perceived visually without the need for a special system.
