Qhov tshwm sim
Feem ntau pob tshab kua.
Qhov ntom
Kwv yees li 1.7 g / cm³
Molecular Structure
Nws yog tsim los ntawm tetramerization ntawm hexafluoropropylene oxide (HFPO). Cov molecule muaj peb ether bonds (-O-) thiab ib pawg carboxyl (-COOH), thiab nyob rau hauv chav kawm ntawm luv luv- saw perfluoroalkyl ether carboxylic acids (PFECA).
Physicochemical Properties
Yooj yim soluble nyob rau hauv polar organic solvents (xws li methanol, DMSO), nrog tsis tshua muaj zog nto zog (kwv yees li 15 mN / m) thiab zoo heev hydrophobic thiab oleophobic zog.
Nws muaj tshuaj lom neeg ruaj khov thiab tiv taus cov kua qaub muaj zog, muaj zog alkalis thiab siab - qhov kub thiab txias.
Purity Standards
Lub purity ntawm kev kho mob-qib siab dua los yog sib npaug rau 99.5% (kuaj los ntawm HPLC), nrog rau kev tswj nruj me ntsis ntawm impurity cov ntsiab lus:
Cov hlau hnyav (Pb, Cd, Hg): Tsawg dua lossis sib npaug li 0.1 ppm;
Cov kuab tshuaj seem (methanol, acetone): Tsawg dua lossis sib npaug li 500 ppm;
Cov ntsiab lus noo noo: Tsawg dua lossis sib npaug li 0.1%.
Khoom Qhia
Kev Kho Mob -Qib Daim Ntawv Thov Teb
Nto hloov kho cov cuab yeej kho mob
Anticoagulant Txheej: Grafted rau saum npoo ntawm cov hlab plawv stents, cov hlab ntsha, thiab lwm yam khoom siv los ntawm covalent bonds, txo platelet adhesion tus nqi (los ntawm 40%) thiab txo qhov kev pheej hmoo ntawm thrombosis.
Lubricating Txheej: Siv rau catheters, endoscopes, thiab cov cuab yeej zoo sib xws, txo cov kev sib txhuam coefficient ntawm 30-50%, txhim kho kev ua haujlwm smoothness, thiab txo cov ntaub so ntswg puas.
Antifouling Txheej: Tiv thaiv cov adhesion ntawm biofilms (xws li cov kab mob thiab cov proteins), ncua kev pab cuam lub neej ntawm cov cuab yeej thiab txo qhov kev pheej hmoo ntawm kev kis kab mob (xws li kev cog hniav).
Cov khoom siv biomedical
Blended nrog biodegradable cov ntaub ntawv xws li polylactic acid (PLA) thiab polyethylene glycol (PEG) los tsim cov ntaub so ntswg engineering scaffolds, tswj cov cell adhesion thiab proliferation (nrog rau osteoblast kev ua tau nce los ntawm 25%).
Siv rau kev hloov kho qhov chaw ntawm kev cog hniav, txhim kho osseointegration lub zog los ntawm 30% thiab txo qhov kev qhia ntawm inflammatory yam (IL-6, TNF-) los ntawm 50%.
