Qhov ntxov tshaj plaws uas muaj cov khoom siv hluav taws xob tau tsim nyob hauv Tebchaws Meskas hauv xyoo 1948 los ua cov nplaum nplaum ua los ntawm cov nyiaj thiab epoxy.Lub electromagnetic shielding xim npaj los ntawm lub pob-milled nyiaj hmoov uas tsim los ntawm Hongwu Nano muaj cov yam ntxwv ntawm cov hluav taws xob me me, zoo hluav taws xob conductivity, siab shielding efficiency, muaj zog ib puag ncig thiab kev tsim kho yooj yim.Siv dav hauv kev sib txuas lus, hluav taws xob, kev kho mob, aerospace, nuclear chaw thiab lwm yam kev tiv thaiv cov xim kuj yog tsim rau ABS, PC, ABS-PCPS thiab lwm yam engineering yas nto txheej.Cov ntsuas kev ua tau zoo suav nrog kev hnav tsis kam, siab thiab kub tsis kam, kub thiab av noo, adhesion, hluav taws xob tiv thaiv, thiab electromagnetic compatibility.

3. tooj liab hmoovthiabnickel hmoov

Copper hmoov conductive txheej yog tus nqi qis, yooj yim rau kev thov, muaj cov nyhuv electromagnetic shielding zoo, thiab tau siv dav.Lawv yog cov tshwj xeeb tshaj yog haum rau electromagnetic yoj cuam tshuam ntawm cov khoom siv hluav taws xob nrog engineering plastics raws li lub plhaub, vim hais tias tooj liab hmoov conductive xim tuaj yeem yooj yim txau los yog txhuam ntawm ntau yam duab ntawm cov yas siv los ua qhov chaw, thiab cov yas nto yog metalized los ua ib qho electromagnetic shielding conductive txheej, kom cov yas tuaj yeem ua tiav lub hom phiaj ntawm kev tiv thaiv electromagnetic tsis.Cov duab thiab tus nqi ntawm cov hmoov tooj liab muaj qhov cuam tshuam zoo rau kev ua haujlwm ntawm txheej txheej.Cov hmoov tooj liab muaj cov duab kheej kheej, cov duab dendritic, daim ntawv duab thiab lwm yam.Daim ntawv yog loj dua li qhov chaw sib txuas ntawm lub ntsej muag thiab qhia tau zoo dua conductivity.Tsis tas li ntawd, tooj liab hmoov (nyiaj-coated tooj liab hmoov) yog coated nrog inactive hlau nyiaj hmoov, uas tsis yooj yim rau oxidized.Feem ntau, cov ntsiab lus ntawm cov nyiaj yog 5-30%.Copper hmoov conductive txheej yog siv los daws cov electromagnetic shielding ntawm engineering plastics thiab ntoo xws li ABS, PPO, PS, thiab lwm yam. Thiab cov teeb meem conductive, muaj ntau yam kev siv thiab kev nce qib.

Tsis tas li ntawd, kev ntsuas kev ua haujlwm ntawm electromagnetic shielding cov txiaj ntsig ntawm electromagnetic shielding coatings tov nrog nano-nickel hmoov thiab nano-nickel hmoov thiab micro-nickel hmoov qhia tau hais tias qhov sib ntxiv ntawm nano-nickel hmoov tuaj yeem txo cov electromagnetic shielding efficiency, tab sis nws muaj peev xwm ua rau kom cov khoom siv hluav taws xob zoo. absorption poob vim qhov nce.Qhov sib nqus poob tangent txo qhov kev puas tsuaj los ntawm electromagnetic nthwv dej rau ib puag ncig thiab khoom siv thiab ua rau muaj kev puas tsuaj rau tib neeg kev noj qab haus huv.

4. NanoATOTin Oxide

Raws li ib tug tshwj xeeb muab tub lim, nano-ATO hmoov muaj siab transparency thiab conductivity, thiab muaj dav siv nyob rau hauv cov ntaub ntawv txheej, conductive antistatic coatings, pob tshab thermal rwb thaiv tsev txheej thiab lwm yam teb.Ntawm cov khoom siv optoelectronic tso saib cov ntaub ntawv txheej, ATO cov ntaub ntawv muaj kev tiv thaiv zoo li qub, tiv thaiv glare thiab tiv thaiv hluav taws xob ua haujlwm, thiab tau xub siv los ua cov khoom siv hluav taws xob tiv thaiv hluav taws xob rau kev nthuav qhia.Nano ATO txheej cov ntaub ntawv muaj lub teeb xim zoo nkauj, zoo hluav taws xob conductivity, txhua yam muaj zog thiab ruaj khov.Nws yog ib qho tseem ceeb tshaj plaws kev lag luam siv ntawm ATO cov ntaub ntawv hauv cov khoom siv.Cov khoom siv electrochromic, xws li cov lus qhia lossis lub qhov rais ntse, yog ib qho tseem ceeb ntawm cov ntawv thov nano ATO tam sim no hauv cov zaub.

5. Graphene

Raws li cov khoom siv carbon tshiab, graphene feem ntau yuav yog ib qho tshiab electromagnetic shielding los yog microwave absorbing khoom dua li carbon nanotubes.Cov laj thawj tseem ceeb suav nrog cov hauv qab no:

Kev txhim kho hauv kev ua haujlwm ntawm electromagnetic shielding thiab absorbing cov ntaub ntawv yog nyob ntawm cov ntsiab lus ntawm tus neeg sawv cev absorbing, cov khoom ntawm tus neeg sawv cev absorbing thiab qhov zoo impedance txuam ntawm absorbing substrate.Graphene tsis tsuas yog muaj cov qauv ntawm lub cev tshwj xeeb thiab cov khoom zoo heev thiab cov khoom siv hluav taws xob, tab sis kuj muaj cov khoom siv microwave zoo.Thaum ua ke nrog cov hlau nplaum nanoparticles, cov khoom siv absorbing tshiab tuaj yeem tau txais, uas muaj ob qho tib si sib nqus thiab hluav taws xob poob.Nws muaj qhov zoo ntawm daim ntawv thov kev cia siab nyob rau hauv thaj tsam ntawm electromagnetic shielding thiab microwave absorption.
