Ke hoʻomau nei ka ulu nui ʻana o ka lāʻau lapaʻau, biomedical a me nā ʻoihana olakino i nā makahiki he 15 i hala iho nei e like me nā mea e like me nā fluoropolymers e hālāwai nei i ka koi paʻakikī no nā huahana hou a me nā kaʻina hana.
Ma ka laulā, ke hoʻololi nei nā fluoropolymers i nā plastics ʻē aʻe i nā noi olakino ma muli o ko lākou hiki ke hoʻokō i nā koi kino a me ka biocompatibility o nā lāʻau a me nā mea hana e hiki mai ana.Loaʻa nā Fluoropolymers i kahi hoʻonohonoho kūʻokoʻa o nā pae hoʻokō ma ia mau noi.ʻO kēia mau mea e pili ana i ka biocompatibility, lubricity, sterilization, chemical inertness, kahi ākea ākea e hoʻohana ai i ka wela, haʻahaʻa haʻahaʻa i ka hana ʻana i nā mea hana, kiʻekiʻe-maʻemaʻe me nā haʻahaʻa haʻahaʻa, nā waiwai dielectric, a me ka palapala hōʻoia USP Class VI.
ʻO ka ʻohana o nā fluoropolymers i loaʻa e kūpono ana i nā pono i luna, ʻo ia nā māka o PTFE, FEP, PFA a me PVDF resin mai nā mea hana resin.ʻO ka PTFE (polymer) kahi moʻolelo implant i hoʻopaʻa maikaʻi ʻia no ka hoʻololi ʻana i ka ʻiʻo palupalu ma muli o kona biocompatibility a me ka inertness.Ke hoʻomau nei nā mea hana Resin a me lalo i ka pane ʻana i nā koi hana hou ma o ka hana ʻana i nā hoʻololi kūpono i ka kemika o ka resin a me ka hoʻonohonoho ʻana o nā huahana, kēlā me kēia.
ʻO ka biocompatibility o kēlā me kēia polymer kahi koi nui i nā mea lapaʻau e like me nā catheters, nā moku bio-containment, nā syringes a me nā sutures.ʻO PTFE, FEP a me PVDF nā mea biocompatible i hoʻokumu pono ʻia, a ʻo kā lākou lubricity a me ke kūpaʻa kemika e lilo lākou i mea koho no nā huahana e like me ka multi lumen tubing a me nā mea ʻē aʻe i hoʻohana ʻia i nā kaʻina hana liʻiliʻi.No ka laʻana, hiki i nā kauka lapaʻau ke hana i nā kaʻina hana he nui me ka hoʻohana ʻana i ka catheter hoʻokahi.
Hoʻohana nui ʻia nā Fluoropolymers, ʻoi aku ka PTFE (polymer) a me PVDF i nā membrane microporous.ʻO nā membrane, aia nā piliona o nā pores mai ka 0.01 a hiki i ka 10 microns e hana ma ke ʻano he kānana no nā ʻāpana a me nā bacteria i nā wai koʻikoʻi.ʻO PTFE a me PVDF kekahi o nā polymers liʻiliʻi i hoʻohana ʻia no nā membrane kānana.Hiki ke hoʻololi ʻia nā ʻili o nā membrane polymers e hāʻawi i nā waiwai kānana kikoʻī a hiki ke lilo i hydrophobic (ka wai hoʻohemo) a me ka oleophobic (ʻaila, solvent, haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa wai repelling).Hiki ke hoʻololi ʻia nā membrane PVDF e lilo i hydrophilic (aloha wai) no ka wehe ʻana i nā ʻāpana viral i ka hana ʻana i nā protein therapeutic a me nā antibodies monoclonal.Ua kūpono loa nā membrane blotting PVDF no ka immunoblotting haʻahaʻa (western blot analysis), a me ka nānā ʻana i ka waikawa amino a me ka hoʻonohonoho pūmua.
ʻO nā mea hoʻohana, e like me nā pamu, nā paipu, nā mea hoʻohana i hoʻohana pū ʻia me nā mea lapaʻau pono e hoʻokō i nā hana like a me nā ʻāpana kikoʻī.Kūkulu ʻia nā mea hoʻopili pololei me nā wai me nā fluoropolymers e like me PTFE a me PVDF.No ka laʻana, koi ʻia nā pamu ana e like me nā pamu diaphragm no ke kahe pololei a hiki ke hoʻihoʻi hou ʻia, i kekahi manawa no nā wai hoʻomāinoino.Hoʻohana ʻia nā paipu PTFE a me PVDF i ke kūkulu ʻana i kēia mau pamu no kēia kumu.
ʻO PVDF, ʻoiai he haʻahaʻa haʻahaʻa ka palena wela o ka hoʻohana ʻana ma mua o ka PTFE (polymer), he kiʻekiʻe kiʻekiʻe ka ikaika tensile a me ke kūpaʻa maikaʻi loa i nā wai he nui.He haʻahaʻa haʻahaʻa kona (1.78 g/cc) ma mua o nā fluoropolymers ʻē aʻe (ma kahi o 2.18 g/cc).Ma muli o ka haʻahaʻa haʻahaʻa haʻahaʻa ma mua o nā fluoropolymers ʻē aʻe, ʻoi aku ka maʻalahi o ka hana ʻana i nā huahana e like me nā paipu, nā paipu, nā ʻāpana i hoʻoheheʻe ʻia a me nā kiʻiʻoniʻoni.Hāʻawi ia i kahi kūlana maikaʻi loa a me ka paʻa UV a no laila ke ʻimi nei i nā hoʻohana hou i ka aerospace, sensors, biotechnology a me nā mākeke robotics.
