Mai ko lākou ʻike ʻia ʻana i ka makahiki 1991, ua makemake nui ʻia nā nanotubes carbon e nā mea noiʻi ma ka ʻoihana kemika, physics, a me nā ʻepekema waiwai.Eia nō naʻe, no ka mea maʻalahi loa nā nanotubes kalapona i ka agglomerate, ʻaʻole maʻalahi lākou e hoʻopuehu ʻia i loko o kahi bottleneck i nā noi kūpono.ʻO ka hoʻololi kemika o ka ʻili o nā nanotubes kalapona e hoʻomaikaʻi i ko lākou mau ʻāina he ala kūpono e wehe ai i kēia bottleneck.ʻO ke ʻano hoʻololi kemika ka hana ʻana i ka hopena kemika ma waena o nā nanotubes kalapona a me ka mea hoʻololi e hoʻololi i ke ʻano o ka ʻili a me ke kūlana o nā nanotubes kalapona, i mea e hoʻokō ai i ke kumu o ka hoʻololi.ʻO kekahi o nā mea maʻamau i hoʻohana ʻia ʻo ia nā ʻakika ikaika a i ʻole nā ​​​​ʻakika hui ʻia e hoʻoneʻe i nā hemahema ma ka ʻili o nā nanotubes kalapona e hana i nā hui carboxyl.

Hiki ke hoʻohana ʻia ʻo COOH Multi Walled Carbon Nanotubes i nā mea i hoʻohui ʻia e hoʻomaikaʻi i kā lākou hana.Eia kekahi mau pepa a me nā hualoaʻa noiʻi no ka ʻike.

Ma keʻano he heterogeneous nucleating agent, hoʻemi ka CNT-COOH i ka nui o ka nui o nā pūnaewele phenolic foam a hoʻonui i ka nui o ke kelepona;e like me ka nui o ka CNTCOOH i loko o ka phenolic foam e piʻi aʻe, ua hoʻonui ka ikaika o ka compression modulus a me ke kaomi ʻana o CNT-COOH / phenolic foam composite.

Ma hope o ka hoʻololi ʻana o ka carboxylation o MWCNTs, hoʻomaikaʻi ʻia ka hoʻopuehu ʻana i nā mea matrix ABS, a hoʻomaikaʻi ʻia ke kūpaʻa.I ka manawa like, ua hoʻomaikaʻi ʻia nā waiwai mechanical o ABS / MWCNTs-COOH composite material, a hoʻomaikaʻi ʻia ka ikaika tensile.Ma ke kaʻina hana, e hoʻokumu ʻia kahi ʻāpana kalapona pūnaewele ma luna o ka ʻili o ka mea e hoʻomaikaʻi ai i ka hana pale ahi o ka mea hana.
