hale hana kiʻekiʻe 99% Graphene oxide pauka me ke kumu kūʻai maikaʻi

He nui nā hui oxygen i loko o ka graphene oxide ma kona ʻili. Loaʻa iā ia ka solubility maikaʻi o ka solvent a me ka pilina me nā polymers. ʻO ka nui o ka oxygen o ka hui oxygen he 30-40%, maikaʻi loa ka solubility i ka wai, a ʻoi aku ka nui o ka monolayer ma hope o ka hoʻoheheʻe ʻana ma mua o 99%. ʻO ka nui a me ka mānoanoa o ka microchip mai 0.5 a 3 um a mai 0.55 a 1.2 nm. ʻAʻohe ua.

Loaʻa ka pauka graphene oxide ma o ka hoʻomaloʻo hau ʻana o ka graphene oxide sol. I ka wā o ka hoʻomaloʻo hau ʻana, ʻaʻole e nalowale ka graphene oxide i nā hui oxygen ma luna o ka ʻili a hana i ka overlap ma waena o nā papa graphene oxide. He porous a spongy ka pauka ma hope o ka hoʻomaloʻo ʻana. Hoʻoheheʻe koke a piha ia ma hope o ka hoʻohui ʻana i ka wai, a hoʻihoʻi koke i nā waiwai sol mua.

Hiki ke hoʻopuehu pololei ʻia ka pauka graphene oxide i loko o ka hopena wai a me ka mea hoʻoheheʻe (ʻoi aku ka maikaʻi o ka ultrasound) e loaʻa ai ka hopena hoʻopuehu like a paʻa (e nānā i ke alakaʻi hoʻopuehu no ke ʻano hoʻopuehu kikoʻī).
