Iingxube ze-polypropylene (PP) kunye ne-polyamide 6 (PA6) ene-multiwalled carbon nanotubes (MWNTs) zalungiswa kusetyenziswa iindlela ezahlukeneyo zokucwangcisa kwi-twin-screw micro-compounder.Impembelelo ye-MWNTs kwindlela yokuziphatha yecrystallization yesigaba se-PP kunye nesigaba se-PA6 somxube siye saphandwa ngezifundo ze-crystallization ezingezo-isothermal ngohlalutyo oluhlukeneyo lwe-calorimetric.Ngaphaya koko, impembelelo yokongezwa kwe-compatibilizer (PP-g-MA) kunye nokuguqulwa kwe-MWNTs (m-MWNTs) kunye ne-non-covalent organic modifier (i-Li-tyiwa ye-6 amino hexanoic acid, i-Li-AHA) ifundwe kumxholo wokuziphatha kwecrystallization yePP kunye nePA6 isigaba kumxube.Uphononongo lwecrystallization lubonise ukonyuka okukhulu kweqondo lobushushu bekristale kwisigaba sePP kumdibaniso kubukho be-MWNTs.Ngaphezu koko, ukwenziwa kwesakhiwo se-'trans-lamellar crystalline' equka i-PA6 'trans-crystalline lamellae' kumphezulu we-MWNTs kwaququzelelwa kwimeko yemixube elungiswe nge 'protocol 2' xa kuthelekiswa nemixube ehambelanayo elungiswe nge 'protocol 1' .Uhlalutyo olubanzi lwe-X-ray ye-diffraction lubonise ubukho be-β-polymorph yesigaba se-PP ngenxa yokufakwa kwesigaba se-PA6 kumxube.Ukongezwa kwe-MWNTs kwimixube kuququzelele ukwakhiwa kwe-β-crystalline ngakumbi kwisigaba se-PP.Kubukho be-m-MWNTs, i-β-fraction ephezulu yabonwa kwisigaba se-PP xa kuthelekiswa nomxube kunye nee-MWNT ezicocekileyo.Ukongezwa kwe-PP-g-MA kucinezele ukubunjwa kwesigaba se-β kwisigaba se-PP kwi-blend.X-reyi bulk texture uhlalutyo lubonise ukuba ukubandakanywa kwe-PA6 kunye ne-MWNT ecocekileyo / eguquliweyo iye yaphembelela ubungakanani bokuqhelaniswa namatyathanga e-PP ukuya kwiinqwelomoya zekristale ezikhethekileyo kwiingqungquthela ezahlukeneyo ze-PP kunye ne-PA6.
