Vim li cas? Qee cov hydrogels tuaj yeemnqus ntau li 600 npaug ntawm lawv cov ntim dej qub. Lawv yuav nqus dej huv ntau dua vim nws muaj tsawg ions. Cov dej kais dej muaj ions, yog li cov hydrogel yuav tsis nqus dej ntau npaum li cov dej huv.
Hydrogels nqus dej li cas?
dej-absorbing polymers, uas yog cais raws li hydrogels thaum sib xyaw, nqus cov dej daws los ntawm hydrogen bonding nrog dej molecules. SAP lub peev xwm nqus dej nyob ntawm qhov ionic concentration ntawm cov kua dej aqueous.
Puas yog hydrogels nqus tau?
Polymer hydrogels synthesized los ntawm cov tshuaj sib txuas ntawm acrylate lossis acrylamide monomers tuaj yeem nqus tau ntau dua 100 npaug ntawm lawv qhov hnyav hauv dej. … Tib cov gels kuj yog superabsorbent thiab muaj peev xwm imbibe mus txog 3000 npaug lawv qhov hnyav hauv dej (uas ntseeg tau tias yog cov ntaub ntawv).
YPob hydrogels yaj hauv dej?
Pharmaceutical hydrogel tshuaj xa khoom tuaj yeem o tuaj yeem ua rau muaj dej, yog li hloov kho kom tsis txhob yaj hauv ob qho tib si acidic thiab nruab nrab nruab nrab hauv ib puag ncig lom neeg.
Puas yog hydrogels hydrophobic?
Hydrogels txhais tau tias yog peb-dimensional crosslinked hydrophilic polymeric tes hauj lwm uas muaj peev xwm ntawm imbibing mus txog ntau txhiab zaus lawv qhov hnyav qhuav hauv dej lossis cov kua roj lom [2, 3].
