ʻO ka hoʻopiʻi conductive mua loa i paʻi ʻia he patent i hoʻopuka ʻia e ʻAmelika Hui Pū ʻIa i ka makahiki 1948 i hana i ke kālā a me ka resin epoxy i mea hoʻopili conductive.ʻO ka pena pale electromagnetic i hoʻomākaukau ʻia me nā pauka kālā i hoʻoheheʻe ʻia e Hongwu Nano i nā hiʻohiʻona o ka haʻahaʻa haʻahaʻa, conductivity maikaʻi, kiʻekiʻe o ka pale ʻana, ikaika ka hoʻomanawanui ʻana i ke kaiapuni, a me ka hana maʻalahi.Hoʻohana nui ʻia lākou i ke kamaʻilio, ka uila, ka lāʻau lapaʻau, aerospace, nā hale nuklea a me nā mea ʻē aʻe.He kūpono hoʻi ka pena pale no ka uhi ʻana o ka ʻili o ABS, PC, ABS-PCPS a me nā mea ʻenehana ʻenehana ʻē aʻe.ʻO nā hōʻailona hana e pili ana i ka pale lole, ke kiʻekiʻe a me ka haʻahaʻa haʻahaʻa haʻahaʻa, ka haʻahaʻa a me ka pale wela, ka hoʻopili ʻana, ka pale uila, ka hoʻohālikelike electromagnetic, etc.

2.3 Ka pauda keleawe a me ka pauda nickel

He haʻahaʻa ke kumu kūʻai ʻo Copper powder conductive pena a he maʻalahi ke pena, he hopena pale electromagnetic maikaʻi nō hoʻi, a no laila ua hoʻohana nui ʻia.He mea kūpono loa ia no ka hoʻopili ʻana i ka nalu anti-electromagnetic o nā huahana uila me nā plastik ʻenekinia e like me ka pūpū, no ka mea, hiki ke hoʻopuʻi ʻia a palaki ʻia ka pena kalaiwa keleawe.Hoʻopili ʻia nā ʻili plastik o nā ʻano like ʻole e hana i kahi papa conductive pale electromagnetic, i hiki i ka plastic ke hoʻokō i ke kumu o ka pale ʻana i nā nalu electromagnetic.ʻO ka morphology a me ka nui o ka pauka keleawe he hopena nui i ka conductivity o ka uhi.He ʻano spherical, dendritic, a me he flake ka pauka keleawe.ʻOi aku ka nui o ke ʻano o ka flake ma mua o ke ʻano spherical a hōʻike i ka conductivity ʻoi aku ka maikaʻi.Eia kekahi, ua uhi ʻia ka pauka keleawe (ka pauka keleawe i uhi ʻia) me ka pauka kālā metala ʻole, ʻaʻole maʻalahi ke oxidize, a ʻo ka ʻike kālā he 5-30%.Hoʻohana ʻia ka copper powder conductive coating no ka hoʻoponopono ʻana i ka pale electromagnetic o ABS, PPO, PS a me nā mea ʻenehana ʻenehana a me ka lāʻau A me ka conductivity uila, he ākea ka nui o ka noi a me ka waiwai hoʻolaha.

Eia kekahi, ʻo ka hopena o ke ana ʻana i ka hopena electromagnetic o ka nano nickel powder a me ka electromagnetic shielding coatings i hui pū ʻia me ka nano a me ka micron nickel powder e hōʻike ana i ka hoʻohui ʻana o ka nano Ni particle hiki ke hōʻemi i ka pono pale electromagnetic, akā hiki ke hoʻonui i ka nalowale absorption.Hoʻemi ʻia ka tangent nalowale magnetic, a me ka pōʻino o ke kaiapuni, nā mea hana a me ke olakino kanaka i hoʻokumu ʻia e nā hawewe electromagnetic.

2.4 Nano Tin Antimony Oxide (ATO)

ʻO ka pauka Nano ATO, ma ke ʻano he mea hoʻopihapiha kū hoʻokahi, he ʻokoʻa kiʻekiʻe a me ka conductivity, a me kahi ākea o nā noi i nā kahua o nā mea hoʻonaninani hōʻikeʻike, nā pale antistatic conductive, a me nā uhi insulation thermal transparent.Ma waena o nā mea hoʻonaninani hōʻike no nā mea optoelectronic, aia nā mea nano ATO i nā hana anti-static, anti-glare a me nā anti-radiation, a ua hoʻohana mua ʻia e like me ka hōʻike ʻana i nā mea pale pale electromagnetic.Loaʻa i nā mea hoʻopili nano ATO i ka ʻike ʻana i ke kala māmā, ka conductivity uila maikaʻi, ka ikaika mechanical a me ka paʻa, a ʻo kā lākou noi no ka hōʻike ʻana i nā hāmeʻa kekahi o nā noi ʻoihana nui loa o nā mea ATO i kēia manawa.ʻO nā mea uila electrochromic (e like me nā hōʻike a i ʻole nā ​​​​windows akamai) i kēia manawa he mea koʻikoʻi o nā noi nano-ATO i ke kahua hōʻike.

2.5 Graphene

Ma ke ʻano he ʻano mea kalapona hou, ʻoi aku ka nui o ka graphene e lilo i ʻano hou o ka pale electromagnetic maikaʻi a i ʻole nā ​​mea hoʻoheheʻe microwave ma mua o carbon nanotubes.ʻO nā kumu nui e pili ana i kēia mau ʻano:

①He kiʻi ʻoniʻoni palahalaha hexagonal ʻo Graphene i haku ʻia me nā ʻātoma kalapona, kahi mea ʻelua-dimensional me ka mānoanoa o hoʻokahi wale nō kalapona kalapona;

② ʻO Graphene ka nanomaterial ʻoi aku ka lahilahi a paʻakikī loa i ka honua;

③ ʻOi aku ka kiʻekiʻe o ka conductivity thermal ma mua o nā nanotubes carbon a me nā daimana, hiki i kahi 5 300W/m•K;

④ ʻO Graphene ka mea me ka liʻiliʻi liʻiliʻi o ka resistivity i ka honua, 10-6Ω•cm wale nō;

⑤ ʻOi aku ka kiʻekiʻe o ka neʻe electron o ka graphene ma ka lumi wela ma mua o ka nanotubes kalapona a i ʻole nā ​​kristal silikona, ʻoi aku ma mua o 15 000 cm2/V•s.Ke hoʻohālikelike ʻia me nā mea kuʻuna, hiki i ka graphene ke haki i nā palena kumu a lilo i mea hoʻoheheʻe hawewe hou e hoʻokō i nā koi o ka absorption.Loaʻa i nā mea hawewe nā koi o "ka lahilahi, māmā, ākea a ikaika".

ʻO ka hoʻomaikaʻi ʻana o ka pale electromagnetic a me ka hoʻopili ʻana i ka hana waiwai e pili ana i ka ʻike o ka mea hoʻopili, ka hana o ka mea hoʻopili a me ka hoʻohālikelike maikaʻi ʻana o ka substrate absorbing.ʻAʻole wale ʻo Graphene kahi hoʻolālā kino kūʻokoʻa a me nā waiwai mechanical a me electromagnetic maikaʻi, akā loaʻa pū kekahi mau waiwai absorption microwave maikaʻi.Ma hope o ka hoʻohui ʻia ʻana me nā nanoparticles magnetic, hiki ke loaʻa i kahi ʻano mea hoʻoheheʻe hou, nona nā poho magnetic a me ka uila.A loaʻa iā ia nā manaʻo noiʻi maikaʻi i ke kahua o ka pale electromagnetic a me ka lawe ʻana i ka microwave.

No nā mea pale electromagnetic maʻamau maʻamau nano pauka, loaʻa nā mea ʻelua e Hongwu Nano me ka paʻa a me ka maikaʻi.
