캡톤테이프의 설명과 구입시 주의사항

중국에서 캡톤테이프 구입시 조심하셔야 합니다
내열성이 전혀 없는 짝퉁 테이프가 판매되고 있습니다
Marsklepios : 오늘 배송된 캡톤테이프를 테스트 해보니 다행이 녹지는 않네요.
지금까지 별 생각이 없었는데 테이프도 후기 잘보고 구입해야겠어요.
강가딘 : 영상 잘 봤습니다.운에 맞겨야 겠네요,,일일이 체크할 수 도 없고....
aerzest sd : 영상 잘봤습니다. 중국산은 열에 약하군요. 다른 스펙도 믿기 어렵겠지요...다른 캡톤 테이프 추천해주실게있나요. 3m은 좀 비싸네요...
xer xer : 저도 알리산 캡톤테이프 가지고 있는데, 버려야겠군요.
배창희 : 에궁

많이 샀는데 역시 중국산

Kapton Tape Supercapacitor?

Can you make a supercapacitor from kapton tape? Yep! Using a laser, we can decompose the Kapton (polyimide) into a graphene "foam" via a process known as Laser Induced Graphene. This form of graphene makes an excellent material for electrostatic double-layer supercapacitors. It has reasonable conductivity and a very large surface area due to the foamy nature, which allows good contact with the electrolyte.

Juraj Variny : Did you try to actually charge and discharge the capacitor into some circuit? Hundreds of microfarads are plenty enough to light up an LED (if it works at over 2 volts of course - you never said the actual testing voltage or I missed it) .
vipulnath1 : Great work! ...Is it still flexible, bendable?
Mark Jay : COOL!
Thaddeus Maximus : Take a laser to an intumescent paint that has been thinned by spin coating and see what you get.
Josh Maxwell : Edit: I just read your pinned comment, I'm a changed man now and I know now how wrong my ways were mere seconds in the past. Makes a lot of sense now, scratch that second paragraph.

Since you're already into basic manual and cnc machining you might wanna look into DIY EDMachining devices. There's a guy here on youtube (BAXEDM) who's promoting both the technique as well as his own semi small scale driving solution for home shop and espechially small professional EDM machines. I think it would really put you on another level with the type of accuracy you can get from such a machine, espechially for really small mechanisms or fixtures. I'm not suggesting that you go full blast with it since it is really expensive but if you made some litte experiments with it maybe you can get something small and bodgy to do some things that are a bit more involved than what AppliedScience and AvE did with it. Maybe do some Ender3 style aluminum extrusion rail system and cheap out on every possible part except the electronics.

Coming back to the supercaps, I think taking a page out of the way they layer LiPo packs and similar battery cells industrially would help your consistency and voltage greatly. You might get away with a strip of plastic bag as an insulator between layers and some more tape as well as multiple cell areays which are mostly parallel internally but series to each other. Not that you didn't obviously know all of this but just in case you wanted to try something bigger I think starting with a better layering and structural solution will do more for you than changing pretty much any other aspect short of the materials the anode and kathode are made out of. Getting just the right pressure so that the electrolyte carrier doesn't squeeze dry but also maintains good contact. If you wanted to change the design of the carbon on the tape, I'd go for solid plated opposite of each other with the electrolyte carrier in between to better make use of surface area and the volume of electeolyte but unless I'm mistaken that's probably the approach you wanted to avoid just because that is pretty much mostly everyone does it. I think it was worth trying it. If I had to guess any other reasons for why it'd probably be that you either wanted to get around needing a seperate insulator in addition to the single layer of tape or you had none of these intentions at all and you just wanted to try doing it your way or I'm just too exhausted and reading into stuff way too much trying to analyse the work of someone I don't know personally and just wildly typing for the sake of it.

Anyways, if I didn't presume too much about you and you got through to this point of my message, I really like your channel so far, hope you got something useful from my probably typo ridden and offly long comment. Keep up the cool projects!

Kapton (Polyimide) Tape Overview

HMC Electronics is the leading distributor for Kapton (Polyimide) Tape. Order from us today! http://www.hmcelectronics.com/brands/Kapton-Tape
Hirudin : This is an OVERVIEW, not a REVIEW.
Frank E Davidson : No way is that a mm thick!
Are you 'avin a laugh? Is he 'avin a laugh? : what about kapton voice coil formers? are they made of tape or are they more of a molding? can they be made of tape? I've seen kapton tubes made spiral wound kapton tape, like a toilet roll tube is made of diagonally wound card layers, but I'm not sure voice coil formers are made like that. kapton or 1145 aluminium... idk, what can I get for 1" VC former?
Maxim Ivanov : A dislike for using nonsense units like the Fahrenheit and the thousandths (d e c i m a l s) of the freaking inch.
[METRIC PLEASE]
michaeldibb : When he said 'mil' I thought milimetres, then I realised Americans call a thousands of an inch,
mils. in the UK a mil is slang for mm.
