ʻO nā mea hoʻopili polimer

ʻO ka Adsorption ka hoʻopili ʻana o nā ion a i ʻole nā ​​molekole ma luna o ka ʻili o kekahi māhele ʻē aʻe.Hiki ke hele mai ka adsorption ma o ka physisorption a me ka chemisorption.Hiki i nā iona a me nā molekole ke hoʻopili i nā ʻano ʻili he nui me nā ʻili polymer.ʻO ka polymer kahi mole nui i haku ʻia me nā subunits hou i hoʻopaʻa ʻia e nā kaula covalent.ʻO ka adsorption o nā ion a me nā molekala i ka polymer surfaces ke kuleana i nā noi he nui e like me: biomedical, structural, a me nā uhi.

Hoʻopili i nā mea hoʻopili

ʻO nā pale pale pale protein:Hoʻopili ka protein adsorption i nā pilina i hana ʻia ma ke kikowaena kiko-implant.Hiki i ka protein adsorption ke alakaʻi i ke koko koko, ka pane ʻana o ke kino haole a ma hope o ka hōʻino ʻana o ka hāmeʻa.I mea e pale aku ai i nā hopena o ka hoʻopili protein, ua uhi pinepine ʻia nā implants me kahi uhi polymer e hoʻemi i ka adsorption protein.

Ua hōʻike ʻia nā uhi polyethylene glycol (PEG) e hōʻemi i ka adsorption protein i loko o ke kino.ʻO ka uhi ʻana o ka PEG i loko o nā molekala hydrophilic i hoʻopailua ʻia i ka adsorption protein.Loaʻa i nā protein nā molekole hydrophobic a me nā wahi hoʻoili e makemake ana e hoʻopaʻa i nā molekala hydrophobic ʻē aʻe a me nā wahi i hoʻopaʻa ʻia.Ma ka hoʻohana ʻana i kahi uhi monolayer lahilahi o PEG, pale ʻia ka adsorption protein ma ka pūnaewele.Eia kekahi, ua hoʻonui ʻia ka pale ʻana o ka hāmeʻa i ka protein adsorption, fibroblast adhesion a me bacteria adhesion.

ʻO nā pale antithrombogenic:ʻO ka hemocompatability o kahi lāʻau lapaʻau e pili ana i ka uku o ka ʻili, ka ikehu a me ka topography.ʻO nā mea i nele i ka hemocompatabile e holo i ka pilikia o ka hana ʻana i kahi thrombus, proliferation a hoʻololi i ka ʻōnaehana pale.Hoʻohana ʻia nā uhi polymer i nā mea hana e hoʻonui ai i ko lākou hemocompatability.ʻO nā cascades kemika ke alakaʻi i ka hoʻokumu ʻana i nā ʻōpala fibrous.Ma ke koho ʻana i ka hoʻohana ʻana i nā uhi polymer hydrophilic, e emi ana ka adsorption protein a e emi pū ka manawa o nā pilina maikaʻi ʻole me ke koko.ʻO kekahi o ia polymer coating e hoʻonui ai i ka hemocompatability ʻo ka heparin.ʻO Heparin kahi uhi polymer e launa pū me ka thrombin e pale i ka coagulation.Ua hōʻike ʻia ʻo Heparin e kāohi i ka platelet adhesion, hoʻopiha i ka hoʻoulu ʻana a me ka adsorption protein.

Kūleʻa

ʻO nā hui polymer kiʻekiʻe:Hoʻohana ʻia nā composites polymer kiʻekiʻe i ka hoʻoikaika a me ka hoʻoponopono hou ʻana i nā hale kahiko.Hiki ke hana ʻia kēia mau composites holomua me ka hoʻohana ʻana i nā ʻano like ʻole me ka prepreg, resin, infusion, filament winding a me ka pultrusion.Hoʻohana ʻia nā composites polymer kiʻekiʻe i nā hale mokulele he nui a ʻo kā lākou mākeke nui loa i ka aerospace a me ka pale.

ʻO nā polymers i hoʻoikaika ʻia i ka fiber:Hoʻohana mau ʻia nā polymers i hoʻoikaika ʻia i ka fiber (FRP) e nā ʻenekini kīwila i kā lākou mau hale.Pane nā FRP i ka laina laina-elastically i ke koʻikoʻi axial, e hoʻolilo iā lākou i mea waiwai nui e paʻa i kahi ukana.ʻO ka FRP maʻamau i loko o kahi laminate me kēlā me kēia lamina me nā fiber unidirectional, maʻamau he kalapona a aniani paha, i hoʻokomo ʻia i loko o kahi papa o nā mea matrix polymer māmā.He kūʻē nui nā FRP i ka ʻike ʻana i ke kaiapuni a me ka lōʻihi loa.

Polytetrafluoroethylene:Polytetrafluoroethylene (PTFE) he polymer i hoʻohana ʻia i nā noi he nui e pili ana i nā pale non-stick, nā mea nani, a me nā lubricants.ʻO ka PTFE kahi mole hydrophobic i haku ʻia me ke kalapona a me ka fluorine.ʻO nā paʻa kalapona-fluorine ke kumu o ka PTFE he mea haʻahaʻa haʻahaʻa, kūpono i nā wahi wela kiʻekiʻe a kū i ke koʻikoʻi.ʻO kēia mau waiwai ke kumu ʻole o ka PTFE a hoʻohana ʻia i kahi ākea o nā noi.

ʻO ka hoʻopili ʻana o ka polymer i ka media porous:ʻO ka adsorption kino a me ka mechanical entrapment ʻelua kumu nui o ka paʻa ʻana o ka polymer i ka media porous.He mea nui ka paʻa haʻahaʻa polymer i loko o ka waihona i ka holomua o ka hana polymer EOR.
