Adsorption bụ nrapado nke ion ma ọ bụ ụmụ irighiri ihe n'elu akụkụ nke ọzọ.Adsorption nwere ike ime site na physisorption na chemisorption.Ions na ụmụ irighiri ihe nwere ike ịbanye n'ọtụtụ ụdị elu gụnyere elu polymer.A polymer bụ nnukwu molekul nke mejupụtara subunits ugboro ugboro jikọtara ọnụ site na covalent bond.Mgbasa ozi nke ion na molecules na elu polymer na-ekere òkè n'ọtụtụ ngwa gụnyere: biomedical, structural, na mkpuchi.
Mgbakwụnye mkpuchi
Ihe mkpuchi na-egbochi protein:Protein mgbasa ozi na-emetụta mmekọrịta nke na-eme na ntinye anụ ahụ-ịkụnye.Protein mgbasa ozi nwere ike ibute mkpụkọ ọbara, nzaghachi anụ ahụ nke mba ọzọ na n'ikpeazụ mmebi nke ngwaọrụ ahụ.Iji gbochie mmetụta nke mgbasa ozi protein, a na-ejikarị mkpuchi polymer kpuchie ihe ntinye iji belata mgbasa ozi protein.
E gosipụtawo mkpuchi polyethylene glycol (PEG) iji belata mgbasa ozi protein n'ime ahụ.Ihe mkpuchi PEG nwere mkpụrụ ndụ hydrophilic na-asọ oyi na mgbasa ozi protein.Ndị na-edozi ahụ nwere molekul hydrophobic na saịtị ụgwọ nke chọrọ ijikọ na ụmụ irighiri mmiri hydrophobic ndị ọzọ na saịtị ndị ọzọ ebubo.Site n'itinye mkpuchi monolayer dị mkpa nke PEG, a na-egbochi mgbasa ozi protein na saịtị ngwaọrụ.Ọzọkwa, a na-abawanye nguzogide ngwaọrụ na mgbasa ozi protein, adhesion fibroblast na nje bacteria.
Ihe mkpuchi antithrombogenic:Hemocompatability nke ngwaọrụ ahụike dabere na ụgwọ elu, ike na ọdịdị elu.Ngwa ndị na-adaghị ịbụ hemocompatabile na-etinye ihe ize ndụ nke ịmepụta thrombus, mmụba na imebi usoro ahụ ji alụso ọrịa ọgụ.A na-etinye mkpuchi polymer na ngwaọrụ iji mee ka hemocompatability ha dịkwuo elu.Kemịkalụ cascades na-eduga n'ịmepụta mkpụkọ fibrous.Site na ịhọrọ iji mkpuchi polymer hydrophilic, protein adsorption na-ebelata na ohere nke mmekọrịta na-adịghị mma na ọbara na-ebelatakwa.Otu mkpuchi polymer nke na-abawanye hemocompatability bụ heparin.Heparin bụ mkpuchi polymer nke na-emekọrịta ihe na thrombin iji gbochie coagulation.E gosiputara Heparin na-ebelata nrapado platelet, mmeju mmeju na mgbasa ozi protein.

Ngwakọta polymer dị elu:A na-eji ihe mejupụtara polymer dị elu mee ihe na-ewusi ike na nhazigharị nke ihe owuwu ochie.Enwere ike ịme ngwakọta ndị a dị elu site na iji ụzọ dị iche iche gụnyere prepreg, resin, infusion, filament winding na pultrusion.A na-eji ngwakọta polymer dị elu mee ihe n'ọtụtụ ụlọ ụgbọ elu yana ahịa kachasị ukwuu bụ ikuku na nchekwa.
Polymers na-akwado fiber:Ndị injinia obodo na-ejikarị polymer eme ka eriri (FRP) mee ihe n'ihe owuwu ha.Ndị FRP na-anabata ahịrị-elastically na nrụgide axial, na-eme ka ha bụrụ nnukwu ihe iji jide ibu.Ndị FRP na-abụkarị n'ụdị laminate nwere lamina ọ bụla nwere eriri na-enweghị isi, nke na-abụkarị carbon ma ọ bụ iko, agbakwunyere n'ime oyi akwa nke ihe matriks polymer ọkụ.Ndị FRP nwere nnukwu nguzogide megide mkpughe gburugburu ebe obibi yana nnukwu ịdịte aka.
Polytetrafluoroethylene:PolytetrafluoroethylenePTFE) bụ polymer eji n'ọtụtụ ngwa gụnyere mkpuchi na-adịghị mma, ngwaahịa mma, na mmanu mmanu.PTFE bụ molekul hydrophobic mejupụtara carbon na fluorine.Njikọ carbon-fluorine na-eme ka PTFE bụrụ ihe na-adịghị ala ala, na-eme ka ọnọdụ okpomọkụ dị elu ma na-eguzogide nrụgide nrụgide.Ngwongwo ndị a na-eme ka PTFE ghara imeghachi omume ma jiri ya mee ihe n'ọtụtụ ngwa.
Polymer adsorption na mgbasa ozi porous:Mgbasa ozi anụ ahụ na ọnyà igwe bụ isi ihe abụọ kpatara njide polymer na mgbasa ozi porous.Njide polymer dị ala na nchekwa nchekwa dị mkpa maka ịga nke ọma nke ọrụ polymer EOR.
