In kasta oo heesaha ay badanaa ku qoran tahay "panacea", waa wax aan la dafiri karin in ay leedahay guryo heer sare ah, korantada, taas oo ah sababta ay warshadu u raacaan si ay u kala diraan nanofiller ee polymers ama torrice matrice. In kasta oo aysan lahayn danaha halyeeyada "Dhagaxa u rogmado dahab ah", waxay sidoo kale hagaajin kartaa qayb ka mid ah waxqabadka xisaabta ee matrix kala duwan oo ballaarinaya tirada codsigiisa.

Waqtigan xaadirka ah, agabyada caanka ah ee garaafyada guud ahaan waxaa loo qaybin karaa ku saleysan polymer-ku-saleysan. Waxaa jira waxbarasho badan oo hore loo sameeyo.

Cudurka loo yaqaan 'Epoxy Resin' Garaafku waa macnaha ugu adag adduunka oo wuxuu leeyahay horumar wanaagsan oo koronto iyo kuleyl heer sare ah. Sidaa darteed, sheyga isku-dhafka ah ee ay sameeyeen qaab dhismeedka garaafyada iyo EP waxay leedahay faa'iidooyinka labada oo leh qiime wanaagsan.

     Nano garaafyadaWaxay leedahay dhul ballaaran oo dusha sare ah, oo isbarbardhiga moloshalular ee garaafyada ayaa sameyn kara interface adag oo leh polymer. Kooxo aad u shaqeynaya sida kooxaha hydroxyl iyo geedi socodka wax soo saarka ayaa jaangooyo u rogi doona jaffene-ga oo duuban. Khaladaadkaas nanoscale waxay kor u qaadeen is-dhexgalka inta u dhexeysa garaafyada garaafyada iyo silsiladaha polymer. Dusha sare ee garaafyada shaqeysa waxaa ka mid ah Hydroxyl, Carboxyl iyo kooxaha kale ee kiimikada ah, oo dhisi kara dammaanad adag oo leh polar poly polumers sida polymphethyl methacrylate. Garaafku wuxuu leeyahay qaab laba-cabbir leh oo gaar ah iyo guryo badan oo heer sare ah, oo leh awood weyn oo ku saabsan hagaajinta kuleylka, elektaroonigga iyo astaamaha farsamada ee EP.

1. Garaaf ku yaal Resins-ka 'Epoxy' - Hagaajinta guryaha elektromagnetic

Garaafku wuxuu leeyahay wadooyin sare oo koronto ah iyo dhismayaal elektaroonig ah, oo leh astaamaha qiyaasta daawada hooseeya iyo hufnaanta sare. Waa mid ka mid ah qaab-dhismeedka hab-dhismeedka loo yaqaan 'ephoxy resin resin'. Baarayaasha lagu soo saaray dusha sare ee lagu daweeyey waxay galaan Ep by polympal-ka kumbuyuutar-ku-meel-gaarka ah ee ku meel-gaarka ah. Guryaha dhameystiran ee composites-ka ee u dhigma (sida guryaha farsamada, korantada iyo kuleylka, iwm.) Si weyn ayaa loo wanaajiyey, iyo in la wajaho korantada lagu kordhin karo 6.5 amar oo baaxad weyn.

Japhne-ga wax laga beddelay wuxuu ku qasbayaa resin ephoxy, oo ku daraya 2% garaafyada wax laga beddelay, modulus wax lagu keydiyo ee apositus-ka aposis-ka ee kordhaya 113%, oo ku daraya 4%, xoogga ayaa kordha 38%. Iska caabbinta ep cresin oo saafi ah waa 10 ^ 17 ohm.cm, iyo caabbinta iska caabintu waxay ka dhacaa 6.5 amar oo baaxad weyn ka dib markii lagu daro garaaftir oxide.

2. Codsiga garaafyada ee ku yaal Resiny Resin - Xadgudubka kuleylka

Si ku daridKaarboon-ka kaarboonka (CNTS)Iyo garaaftir xagga resin, marka lagu daro 20% CNTS iyo 20% GNPS, in la wajaho kuleylka ah ee maaddada unugyada ay ku gaari karaan 7.3W / MK.

3. Codsiga garaafyada garaafyada ee 'Epoxy Resin' - olol dib-u-dhac

Markaad ku darayso 5 wt% garaafyada firfircoon ee oniolne ee oxide, oo ah qiimaha dib-u-dhigga ee qulqulka ayaa kordhay 23.7%, iyo markii lagu daray 5 WT%, oo kordhay 43.9%.

Garaafku wuxuu leeyahay astaamaha adag ee adag, xasilloonida cabirka iyo adkaanta. Iyada oo ah modifier resinpier eposin, waxay si weyn u hagaajin kartaa astaamaha farsamada ee agabyada isku-darka, waxayna ka gudbeysaa qaddarka badan ee buurayaasha caadiga ah ee inorganic-ka caadiga ah iyo wax-ka-dhibka hoose ee wax ka badalida iyo khaladaadka kale. Cilmi baadhayaashu waxay codsadeen in la beddelay Go / EP Nanocomposites. Marka W (Go) = 0.0375%, xoogga isku-dhafka ah iyo adkeynta waxyaabaha ku saleysan ee u dhigma oo kordhay 48.3% iyo 1185.2% siday u kala horreeyaan. Saynisyahannadu waxay bartay saameynta wax ka badalida caabbinta daalka iyo adkeynta nidaamka Go / EP: markii W (The W (1%, mossus tensile-ka ah ee ka kooban ku dhawaad ​​12%; Marka W (Go) = 1.0%, adkaanta dabacsan iyo xoogga isku-darka waxaa kordhay 12% iyo 23%, siday u kala horreeyaan.
