Haina Donghua Whare pūawai nanofiber kiriuhi, pāka breathable me te wera ariponga

wā:2020-08-10 Ngā Taunga:

Yu Jianyong \ o te tīma o te Whare Donghua ko pūawai he nanofiber kiriuhi ki te wai pai, haukū permeability, rite tonu ki te rangi tino pai permeability me tākai kawe ia. Nga tētahi poukapa waerau ahurei fluorinated polyurethane (pu), hydrophobic, tākai kawe ia o BN nano electrostatic kopae i muri i te whāranu, ko te utuhia mā te whakahaere i te BN nanotubes takawai te āhuatanga me te taiao e pātahi ana i te pipiwai (RH) i whiwhi te whatunga pai o BN hītari me poareare hanganga o BN whatunga mō te kiriuhi permeability me te tākai kawe ia o te kaupapa pai. I te wa ano, te mahinga synergistic o te hydrophobic waerau te poukapa me te whakapai ake o te mata roughness o te kiriata kia pai ai te wai o te pikitia, me te superhydrophobicity.

Ko te tukanga whakanaonga tauwhāiti o tēnei kiriata ko whakamemeha FPU me DMAc, titaria BN nanometer kiriata kia taea ai te kopae wē i te wā kotahi, kātahi ka hanga FPU/BNx pikitia mai i electrostatic kopae i muri i te ultrasonic maimoa (x ko te kukū o te BN nanometer kiriata). Te kukū o te FPU 6%, te hau fluorinated polyurethane/polyurethane 1/8, a ko te hau o te BN nanosheet 0%, 6%, 12%, 18% a 24%, aua.

I whakaputaina te Pipiri 19 i te ACS tuhitaka i Hoatu te Matu me te Atanga.




1. Tākai kawe ia whakamātau
Kua whakamātautauhia e te hyperplane tākai kawe ia o te kiriata ko 17.9 m/m · K, ko te tākai whakapae kawe ia te 0.29 m/m · K, te Kapor te wai tiketike (WVT) he 11.6 kg/m2 · ra. Te rerekētanga i tākai kawe ia o FPU/BN0 kiriata, FPU/BN18-RH90 te kiriata me te FPU/BN18-RH50 kiriata ka kitea te mārama me te tatau mōrahi i te wera:






2. Hydrophobicity whakamātau
I whakamātautauhia te pikitia ki tētahi Koki whakapā ki te 153° me te hydrostatic o 32 kPa.

3. Whakamātau permeability hau

Kāore e taea te whakamahi i tēnei nanofiber kiriuhi i ngā kākahu hākinakina ki te āwhina i te tutuki o te tinana tangata hāneanea, engari ka taea te whakamahi i ngā rawa hanga. Mā te hoatu i te purei katoa ki tōna breathability, ariponga wera me ngā āhuatanga pāka, ka taea te whakaiti i te whakapaunga pūngao tapeke o te mokowā hanga whakamātao, ko te conducive ki te kauneke o te whanaketanga ā muri ake.
