Kev Tshawb Fawb Daim Ntawv Thov CAS: 60506-81-2|Dipentaerythritol pentaacrylate
Synthesis thiab CharacterizationDipentaerythritol pentaacrylate (DPHPA) tau raug tsim los ntawm esterification, suav nrog dipentaerythritol thiab acrylic acid, nrog p-toluenesulphonic acid ua catalyst. Txoj kev tshawb no tshawb txog qhov cuam tshuam ntawm cov ntsiab lus catalyst, pawg inhibitor thiab cov ntsiab lus, thiab qhov piv ntawm mole ntawm cov khoom lag luam, muab kev nkag siab rau cov kev pom zoo rau nws cov synthesis (Li An-mei, 2006).
Kev siv kho hniavDipentaerythritol penta-acrylate phosphate, ib qho txawv ntawm DPHPA, tau tshawb xyuas los ua lwm yam phosphate ester monomer rau kev sib txuas methacrylate-raws li resins rau yttria-stabilized tetragonal zirconia polycrystals (Y-TZP). Txoj kev tshawb no tau pom qhov ua tau zoo ntawm kev sim PENTA-muaj cov primers hauv kev txhim kho resin-Y-TZP daim ntawv cog lus lub zog thiab elucidated lub peev xwm tshuaj sib txuas cov txheej txheem koom nrog (Ying Chen li al., 2016).
UV-Curable CoatingsKev tshawb fawb txog UV-kho tau cov coatings uas muaj DPHPA, ntawm lwm cov multifunctional acrylate monomers, soj ntsuam tus cwj pwm kho. Txoj kev tshawb no tau siv kev ua haujlwm zoo nanosilica thiab qhov tob profile kom nkag siab txog kev faib tawm thiab hloov pauv ntawm cov monomers, qhia tias DPHPA feem ntau tseem nyob ntawm cov txheej txheej (Ehsan Zarshenas li al., 2013).
Cov ntaub ntawv PolymericPoly (lactic acid) / polyacrylate semi-interpenetrating network tau kawm siv DPHPA. Kev tshawb fawb koom nrog kev sib xyaw PLA nrog DPHPA hauv qhov sib txawv ntawm qhov sib txawv thiab tshuaj xyuas lawv cov photostability thiab cov khoom nto hauv qab UVC hluav taws xob. Txoj kev tshawb no muaj kev cuam tshuam rau kev lag luam ntim khoom, qhia tias PLA / polyacrylate films 's nto roughness thiab tshuaj muaj pes tsawg leeg cuam tshuam los ntawm UV teeb (J. Kowalonek li al., 2016).
Hybrid Monolithic KabDPHPA tau siv nyob rau hauv kev tsim cov kab sib txuas ntawm cov kab sib txuas sib txuas. Cov kab no, tus cwj pwm los ntawm kev ua haujlwm siab thiab kev xaiv, muaj cov ntawv thov hauv cov protein sib cais, ua haujlwm zoo tshaj cov kab lag luam silica. Txoj kev loj hlob no qhib qhov rooj rau kev siv ntau dua hauv kev tshawb fawb proteome thiab capillary electrochromatography (Junqian Ma et al., 2017).
Macroporous Zaj duab xisDPHPA tau ua haujlwm hauv kev tsim cov yeeb yaj kiab macroporous TiO2 los ntawm kev yees duab polymerization-induced theem sib cais. Cov yeeb yaj kiab no, uas ua rau pom kev ua haujlwm photocatalytic siab dua, yog qhov tseem ceeb rau kev siv ib puag ncig xws li decomposition ntawm organic pollutants (Jianxi Yao li al., 2010).
