Researchers at Northwestern University think they ’ve stumble upon an unexpected new economic consumption for the so - called supermaterialgraphene : an easy - to - apply , safer , and inflexible black hair dye that could give other permanent dyes a run for their money . The new dyestuff even made hair immune to frizz and still electricity .
A few years ago , Jiaxing Huang , a professor of Materials Science and Engineering at Northwestern University , made a “ curious observation ” about the great unwashed ’s pick of hair dye while traveling through China . Despite the wide kind of colors available , most people he came across just wanted pitch - bootleg tomentum . And in his domain , there were few things blacker than gunpowder made out of graphene , a material made of unadulterated carbon particle arranged in a beehive normal that ’s incredibly thin , flexible , and strong .
So , in what Huang describes as a “ Friday afternoon experiment , ” he and his team decided to whip up batches of graphene - based dye and test them out on samples of blond human hair’s-breadth . They find the dyestuff could wrap itself tightly and uniformly around pilus strand , creating a waterproof stamp that live for up to 30 washes without fading away . And unlike the conventional cognitive process for most lasting dyestuff — which requires treating hairsbreadth with chemicals like bleach to rifle its original coloring material and pry give the carapace , then total more stiff ( and mayhap carcinogenic ) chemical that can damage the hair and irritate surrounding skin — the graphene dyestuff leave the hair totally unhurt .
“ It does n’t rely on any chemical reaction — you just sweep it on the surface of the hair , comb it , and the hair change color , ” Huang told Gizmodo .
The findings werepublishedin Chem .
Graphene is ordinarily transparent , but when exposed to oxidise agentive role like oxygen and hydrogen , it becomes brown . This graphene oxide , which Huang ’s team used as the base for their dye , can then be turned dark through a variety of ways , including ultraviolet radiation . Huang ’s squad also used chemical like vitamin carbon to further qualify the graphene so that it would easily be dispersed in water ( meaning it would n’t settle to the bottom if leave untouched ) and could be uniformly applied .
away from being about as durable as the permanent dye they matched it up against , the blackest of the dye wad Huang ’s team made was only a smidge less dour . And because of graphene ’s customizable coloring , they were even able to create an “ ombre ” look , mean hair that ’s been dyed different shades of people of color at the same time that blend into one another . mighty now , the range of mountains of colour available is still only bronze to black , though Huang believes that would cover the legal age of coloration preferences .
The graphene also lend the hair its unparalleled property . It made the hair frizz - cogent evidence , as well as a better thermoregulator , such that someone ’s head would theoretically be left cooler on a hot summertime day . And because of graphene ’s current and possible applications in engineering science , Huang thinks the dyestuff could even be used in combination with other near - future engineering science .
“ I took bill of a raft of recent developments in so - called thermo - electronics . These are electric electric circuit and twist that can be now applied to the skin though something like a peg - on tattoo , ” Huang say . “ So if you now have conductive hair , then imagine what you could do to interface the whisker with these circuits . ”
Interesting as Huang ’s dye might be , do n’t require it on grocery store shelves just yet . Huang is still trying to have his Friday afternoon experiment taken seriously . He say he was n’t capable to recover any federal federal agency willing to fund this sort of “ unconventional ” research .
“ The funny affair is , my wife generously confirm the purchase of all the hair samples and beauty supplies that we used , ” he said . “ But I hope people get really interested about this and we ’d for certain like to take it up to the next footprint . ”
That would include clearing regulative hurdles so they could test the hairsbreadth dye with actual mass . Huang believe his dyestuff would have an easier journey being sanction than commercial dyestuff in the past , since animal inquiry indicates that graphene wo n’t cause allergic reaction and nark the skin . And while Huang ca n’t speculate about how much it would be to descale up the output process , he notes that the dye — unlike other cutting - edge lotion of the material — wouldn’t need double-dyed - grade , expensive graphene .
“ I ’m affirmative , ” Huang said . “ I think multitude will really come out looking seriously into this , and then together with , we might start to see this kind of hair dyestuff very soon . ”
