Musanganiswa wepolypropylene (PP) uye polyamide 6 (PA6) ine multiwalled kabhoni nanotubes (MWNTs) akagadzirirwa achishandisa nzira dzakasiyana dzekugadzirisa mune mapatya-screw micro-compounder.Mhedzisiro yeMWNTs pakuita kwekristalllization yePP chikamu uye PA6 chikamu chemusanganiswa chakaongororwa kuburikidza neasiri-isothermal crystallization zvidzidzo nekusiyanisa scanning calorimetric ongororo.Uyezve, mhedzisiro yekuwedzerwa kweiyo comptibilizer (PP-g-MA) uye shanduko yeMWNTs (m-MWNTs) ine isina-covalent organic modifier (Li-munyu we6 amino hexanoic acid, Li-AHA) ine zvakare. yakadzidzwa mumamiriro ezvinhu kune crystallization maitiro ePP uye PA6 chikamu mumusanganiswa.Zvidzidzo zvekristalllization zvakaratidza kuwedzera kukuru kwekushisa kwekristalllization yePP chikamu mumusanganiswa pamberi peMWNTs.Zvakare, kuumbwa kwe 'trans-lamellar crystalline' chimiro chinosanganisira PA6 'trans-crystalline lamellae' paMWNTs pamusoro chakafambiswa mumamiriro ezvinhu emusanganiswa wakagadzirwa kuburikidza ne 'protocol 2' kana zvichienzaniswa neinowirirana misanganiswa yakagadzirwa kuburikidza ne 'protocol 1' .Wide angle X-ray diffraction analysis yakaratidza kuvapo kwe-β-polymorph yePP chikamu nekuda kwekubatanidzwa kwePA6 chikamu mumusanganiswa.Kuwedzerwa kweMWNTs mumisanganiswa kwakafambisa imwezve β-crystalline chimiro chechikamu chePP.Pamberi pem-MWNTs, yakakwira β-fraction yakaonekwa muchikamu chePP kana ichienzaniswa nemusanganiswa ane pristine MWNTs.Kuwedzerwa kwePP-g-MA kwakadzvinyirira kuumbwa kwe-β-chikamu muchikamu chePP mumusanganiswa.Ongororo yeX-ray yakawanda yakaratidza kuti kuiswa kwePA6 pamwe neyakagadziridzwa/yakagadziridzwa MWNTs kwakapesvedzera hupamhi hwekutarisa kwengetani dzePP kune dzakanangana ndege dzekristaro mumhando dzakasiyana dzakasanganiswa dzePP nePA6.
