Tae-huri-emitting atamai textiles me te urupare tākai takirua

wā:2019-12-09 Ngā Taunga:

E pātahi ana ki te hiko, uara Waikawatanga, stimulation matū, ko nga mea tākai stimulation e ngāwari ana ki te whakatinana kaupapa i o matou ra katoa, kia tākai te katoa o te momo urupare ki te textiles atamai, ārai counterfeiting, sensing, me te maha o ngā āpure i rongonui māharahara, tākai e pā ana te urupare ki te momo matū i te huringa o te taiao ā-waho me te huri i ōna āhuatanga ōkiko, tae atu ki tākai discoloration ki te rangahau i te āpure o te textiles atamai he momo matū.

 

 

 

Heoi, thermochromic rawa he tepenga taiao. Hei tauira, kāore i te ngāwari te pupuri i te huringa tae o te rawa i roto i te taiao pōuri, ko ēhea ngā hua i te tepenga nui i roto i kiko taupānga. Na reira, he kōhukihuki te whakahaere i te matū thermochromic me ngā āhuatanga thermofluorescent e taea ai te roha i tana awhe taupānga.

Aita i maoro a'e, i te ngātahitanga me Te Texas i Tētahi&M whare wānanga, kua jiangnan te whare wānanga pūawai he thermally rata me ngā taumahi takirua o thermochromism me te thermofluorescence. He nanoparticle te matū o te waikano, he papura te kōnenehu waikano i te taha o te whakatōtā o tetraethyl orthosilicate, ka uhi i silica makawe nanoparticles me diindoles (IQA) pararopi waikano molecules me waikawa waiwaihā.

 

 

Ka taea te waikano te whakawhero i te paparau papanape mā te ōkawa i te aratuka dyeing, na, ko te whakawhero paparau papanape pupuri ko ngā āhuatanga o te matū tuatahi nanocomposite, ka taea te realize i ngā huringa takirua o te tae me te fluorescence mahinga ki te huringa o tūrama āria wera.

 

 

Ngā āhuatanga o te nanoparticles hiato


Ko ngā hua i whakaaturia e te whakawhero papanape ka whakaaturia te huringa tae me te pūrata nui fluorescence te huringa āhua o te wā tūturu me te kore whakahoki. I muri i te whakawera, ko ngā huringa tae papanape mai i te waiporoporo hōhonu ki te karaka i raro i te marama ari. I raro i uv marama (365 nm), ko ngā huringa papanape mai i te puhoi-kore te āhua korekoreko ki te āhua o te taha o te korekoreko koura..

 

 

Ngā huringa tae o whakawhero pūru i te hauraro rerekē

 

Fluorescence ngā huringa o whakawhero pūru i ētahi atu hauraro


Ko te thermochromic huarahi o te matū ko te e dissociation, ko te outlook huarahi o IQA molecules i roto i te waikawa waipiro whakarewa. Mai i te dissociation me outlook o IQA molecules whakawhirinaki i te whakakoero, i te solidification o te whakarewa. Na reira, ka taea te discoloration te pāmahana mā te huri i te wae whakarewa.

Ka tuku tēnei akoranga i tētahi ariā hōu mō te hoahoanga mahinga-maha tākai urupare kikaka textiles. I whakaputaina ngā hua rangahau whai pānga ki ngā Mahinga Arā Atu Anō i raro i te taitara o "te mahinga-Thermoresponsive-takirua-mita Waikano mō te Taupānga Pueru Atamai".
