Polyethylene Thermal Interfacial Materials
Prof. Joong Hee Lee thiab Prof. Ok-kyung Park los ntawm Kaus Lim Qab Teb tau sib koom ua qhov kev txhim kho tshiab hauv kev taw qhia ntawm kev sib tshuam ntawm thermal tsis kam ntawm BNNS / LDPE polymer composites. Pab pawg tau tshaj tawm cov txheej txheem zoo hluavtaws los npaj cov roj av tsawg-ceg ntoo (BNT) (TIM). Txhawm rau txhim kho cov khoom siv thermomechanical ntawm BNNS / LDPE, qhov saum npoo ntawm BNNS tau hloov kho nrog luv PE chains (PE-g-BNNS) los ntawm nitro coupling cov tshuaj tiv thaiv, uas txhim kho kev sib txuas ntawm BNNS thiab LDPE.
Cov txiaj ntsig tau pom tias nyob rau hauv dav hlau thermal conductivity ntawm PE-g-BNNS / LDPE tau nce 22% thiab cov thermal conductivity nyob rau hauv ntsug tau nce 66% piv nrog BNNS / LDPE. Kev ua haujlwm thermal hluav taws xob kuj tau txhim kho los ntawm kwv yees li 11% piv rau LDPE ntshiab. Tsis tas li ntawd, lub zog tensile ntawm PE-g-BNNNS / LDPE tau nce 66% thiab modulus los ntawm 350% piv rau LDPE ntshiab, qhia tias PE-g-BNNNS / LDPE tuaj yeem siv los ua TIM kom tau raws li daim ntawv thov siab. -tech electronic devices.
Cov txiaj ntsig kev tshawb fawb tau sau tseg tias "Boron nitride nanosheet reinforced polyethylene nanocomposite zaj duab xis rau kev ua haujlwm siab kub-melt nplaum hom thermal interfacial khoom" tau luam tawm hauv Polymer.
Shengyang New Material Co., Ltd. tau cog lus rau kev tsim cov boron nitride thiab boron nitride ua cov khoom, thiab tuaj yeem kho ntau yam boron nitride insulating ceramic qhov chaw raws li cov neeg siv khoom xav tau. Tiv tauj peb yog tias tsim nyog.
