Qhov tseem ceeb ntawm kev hloov pauv cuam tshuam ntawm aluminate coupling cov neeg ua haujlwm hauv cov khoom siv sib xyaw ua ke yog los ntawm lawv cov qauv molecular tshwj xeeb thiab sib xws physicochemical ua haujlwm hauv paus.Lawv cov haujlwm tseem ceeb yog tsim los ntawm amphiphilic molecular tsim, interfacial bonding mechanisms, thiab compatibility txoj cai. Cov ntsiab lus sib sau ua ke ua lub hauv paus theoretical thiab cov tswv yim tsim kom muaj tus choj zoo ntawm inorganic fillers thiab organic matrices.
Nyob rau theem molecular, aluminate coupling agents yog nyob rau hauv ib ncig ntawm txhuas atoms, txuas polar functional pawg thiab nonpolar ntev -chain alkyl pawg los ntawm bridging oxygen bonds, tsim ib tug amphiphilic qauv nrog ob qho tib si inorganic thiab organic affinity zog. Polar xaus feem ntau muaj cov carboxyl, ester, lossis phosphate pawg, uas tuaj yeem sib koom ua ke, ionic, lossis muaj zog hydrogen- khi nrog hydroxyl pawg, hlau oxides, lossis cov hlau ions raug rau saum npoo ntawm inorganic fillers, ua kom muaj zog adsorption. Tsis yog-cov saw ntev ntev yog feem ntau aliphatic lossis hloov pauv cov ntu polymer, uas tuaj yeem nkag mus tob rau hauv cov organic polymer chains, ua tiav kev sib raug zoo los ntawm van der Waals rog thiab cov saw hlau sib txuas, yog li txo qis kev sib tshuam ntawm kev sib cais thiab inhibiting theem sib cais.
Nyob rau hauv cov nqe lus ntawm interfacial mechanisms, aluminate coupling agents migrate thiab sib sau nyob rau hauv lub interfacial cheeb tsam ntawm lub muab tub lim thiab lub matrix thaum lub sij hawm ua, taw qhia rau tsim "molecular txuas hniav," nrog ib tug kawg anched rau lub muab tub lim thiab lwm yam integrated rau hauv matrix. Cov nyhuv bridging no tsis tsuas yog txhim kho cov dispersion ntawm cov muab tub lim nyob rau hauv lub matrix tab sis kuj tseem txhim khu kev sib raug zoo ntawm kev sib raug zoo, tso cai rau kev ntxhov siab kom hloov tau zoo ntawm ob theem, txo qhov tsis xws luag thiab tawg pib, thiab yog li txhim kho cov khoom siv thiab qhov ntev ntawm cov khoom sib xyaw.
Tsis tas li ntawd, kev sib txuas ntawm cov pa oxygen ntawm aluminate coupling cov neeg ua haujlwm tso cai rau cov molecules nrog qee yam thermal stability thiab spatial tunability, ua rau lawv tswj hwm cov txheej txheem kev ncaj ncees thiab kev ua haujlwm tau zoo thaum lub sijhawm ua haujlwm kub - kub thiab nyob rau hauv ib puag ncig sib txawv. Qee cov qauv koom nrog cov pab pawg ua haujlwm reactive, ua rau lawv koom nrog hauv polymerization lossis hla - txuas cov kev cuam tshuam ntawm qhov cuam tshuam thiab tsim cov ntawv cog lus nrog cov matrix, ntxiv dag zog rau kev sib koom ua ke.
Yog li ntawd, lub hauv paus ua haujlwm ntawm aluminate coupling agents yog nyob rau hauv kev tsim qauv ntawm lawv cov qauv molecular, ntau haiv neeg ntawm lawv cov kev sib cuam tshuam, thiab kev tswj hwm ntawm lawv cov kev sib raug zoo. Cov yam ntxwv no muab kev txhawb nqa theoretical thiab txhim khu kev qha kev ruaj ntseg rau lawv daim ntawv thov dav hauv ntau hom xws li yas, roj hmab, thiab txheej.
