ako jednu z technologii, ktora my prisla zaujimava vyskusat v ‘domacom’ prostredi bolo pokovovanie roznych materialov, alebo elektrolyza. mojim povodnym zamerom bolo touto technologiou v nejakom zmysle spracovavat material, po navsteve SAV a oboznameni sa s technologiou electrospinningu som sa zacal vsak sustredit na pokovovanie plastou medou → aby boli vodive (vodive boli aj pred tym, lebo musia byt vodive aby som ich pokovoval, ale teda pokovene su krajsie asi) a pouzitelne v technologii electrospinningu ako matrica.

postupne som zdokonaloval technologiu, ako udrzat vodne sklo na plaste. postup: vytlacok z PLA sa ponori na cca 15min do acetonu (v zavislosti od poctu vrstiev a vyplne (cim menej, tym menej)), necha sa 15min odlezat, potom sa ponori do zmesy grafitu a vodneho skla (150g/980g) (treba si otestovat, ktory grafit je vodivy, jediny ktory mi fungoval bolo 150g balenie graphite powder od Cretacolor). vodne sklo sa necha zaschnut, a ponori sa znova. Ja som daval dve vrstvy lebo som nestihal, ale optimum by bolo asi aspon 3 vrstvy. po zaschnuti poslednej vrstvy som vytlacok na 3-5s ponoril do 10% bieleho octu (pri skuskach s vodnym sklom som zistil, ze tuhne aj v octe). toto vsetko robime aby nam vodne sklo v roztoku vody, modrej skalice a kyseliny sirovej nodpadavalo z vytlacku (opadava aj tak, ale je to lepsie)

one of the technologies that I found interesting to try in a 'home' environment was the electroplating of various materials, or electrolysis. my original intention was to use this technology to process the material in some way, but after visiting the Slovak Academy of Sciences and becoming familiar with the electrospinning technology, I started to focus on plating plastic with copper → to make them conductive (they were conductive before, because they have to be conductive for me to plate them, but they are probably more beautiful when plated) and usable for electrospinning as a matrix.

I gradually improved the technology of how to keep waterglass on plastic. procedure: the PLA print is immersed in acetone for about 15 minutes (depending on the number of layers and infill (the less, the less)), left to dry for 15 minutes, then immersed in a mixture of graphite and waterglass (150g/980g) (you need to test which graphite is conductive, the only one that worked for me was a 150g package of graphite powder from Cretacolor). the waterglass is allowed to dry, and immersed again. I applied two layers because of the deadline, but the optimum would be at least 3 layers. after the last layer dried, I immersed the print in 10% white vinegar for 3-5 seconds (during tests with waterglass, I found that it also solidifies in vinegar). we do all this so that the waterglass in the solution of water, copper sulphate and sulfuric acid does not fall off the print (it still falls off, but it's better)
