Mechanism ntawm Action
Lub reactivity thiab kev siv hluav taws xob ntawm Cyclohexyl (dimethoxy) methylsilane qia los ntawm cov luag haujlwm ntawm nws pawg ua haujlwm.
- Hydrolyzable Alkoxy Pawg (Si-OCH₃):Ob pawg methoxy (-OCH₃) txuas nrog silicon yoghydrolytically labile. Thaum raug dej (txawm tias atmospheric noo noo), lawv nkag mushydrolysis, hloov mus rau reactive silanol (Si-OH) pawg.
- Condensation & Bond Formation:Tom qab ntawd cov pawg silanol generatedcondensenrog rau lwm pab pawg silanol (los ntawm tib yam los yog lwm yam molecules) los yog nrog hydroxyl (-OH) pawg muaj nyob rau ntawm substrate nto (xws li, iav, hlau, minerals, polymers). Cov tshuaj tiv thaiv condensation no ua rau muaj zogSi-O-Si los yog Si-O-substrate covalent bonds, tso dej los yog cawv raws li ib tug byproduct.
- Organic Substituent Role:Cov methyl (CH₃-) thiab cyclohexyl (C₆H₁₁-) pawg tsis yog-hydrolyzable. Lawv tseem txuas nrog silicon atom, dhau los ua cov organic "tails" uas tsim los ntawm qhov chaw hloov kho los yog ua ke rau hauv cov pob txha polymer. Cov pawg cyclohexyl loj heev, tshwj xeeb, tuaj yeem faib cov khoom tshwj xeeb xws lince hydrophobicity, steric bulk, thiab hloov solubilitymus rau cov khoom kawg.
Cov txiaj ntsig tseem ceeb & Kev ua tau zoo
- Dual{0}}Functionality:Muab cov chaw reactive (rau kev sib txuas / kev sib txuas) nrog cov organic ruaj khov (rau kev hloov khoom vaj khoom tsev) hauv ib qho molecule.
- Kev Hloov Kho Nto Zoo:Tsim ib qho chaw ruaj khov, sib raug zoo nrog cov organic-silicon monolayer rau ntawm qhov chaw tsis muaj kab mob, txhim kho kev sib raug zoo nrog cov organic matrices lossis imparting dej-repellency.
- Versatile Building Block:Ua hauj lwm raws li ib qho tseem ceeb synthon rau tsim kev cai organosilicon architectures, nrog rau dendritic thiab hyperbranched polymers.
- Tswj Reactivity:Cov pab pawg dimethoxy muab qhov sib npaug ntawm cov tshuaj reactivity (ntau dua reactive dua ethoxy) thiab tuav ruaj khov piv rau trichloro lossis trialkoxy analogs, tso cai rau kev tswj xyuas.

FAQ: Cov lus nug nquag nug
Q: Dab tsi yog qhov teeb meem tseem ceeb thiab cov txheej txheem kev nyab xeeb?
A: Cov tshuaj no yog nplaim taws (flash point 73 degree) thiab ya raws -sensitive. Nws tuaj yeem ua rau tawv nqaij thiab qhov muag khaus. Ib txwm tuav hauv lub qhov dej - qhov cua fume hood, hnav PPE tsim nyog (cov hnab looj tes, tsom iav kev nyab xeeb), thiab kom deb ntawm sparks, cua sov, thiab dej. Khaws nyob rau hauv ib qho chaw inert.
Q: Puas yog soluble hauv dej?
A: Tsis yog, nws tsis yog soluble hauv dej. Qhov tseeb, nws reacts nrog dej los ntawm hydrolysis. Nws yog soluble hauv feem ntau cov organic, dej -cov kuab tshuaj dawb.
Q: Qhov txawv ntawm qhov no thiab lwm yam methyl -dimethoxy silanes (xws li Methyltrimethoxysilane) yog dab tsi?
A: Qhov sib txawv tseem ceeb yog cov organic hloov pauv. Methyltrimethoxysilane (CH₃Si(OCH₃)₃) muaj peb pawg methoxy reactive thiab ib pawg methyl, ua rau nws ua tau zoo heev crosslinker. Cyclohexyl (dimethoxy) methylsilane tsuas muaj ob pawg methoxy (tsawg dua crosslinking muaj peev xwm) thiab lub nplhaib loj, hydrophobic cyclohexyl nplhaib, uas muaj kev cuam tshuam ntau dua hauv kev hloov kho cov khoom nto thiab polymer sab chains.
Q: Yuav tsum khaws cia ntev li cas -lub sij hawm?
A: Rau lub neej txee siab tshaj plaws, khaws cia hauv qhov qub, kaw lub raj mis kom nruj hauv qab daim pam qhuav, tsis muaj roj (nitrogen / argon) nyob rau hauv qhov chaw txias, qhuav, txias txias. Kev raug rau huab cua yuav ua rau maj mam hydrolysis thiab tsim ntawm siloxanes.
