Li-blends tsa polypropylene (PP) le polyamide 6 (PA6) tse nang le li-multiwalled carbon nanotubes (MWNTs) li ile tsa lokisoa ho sebelisoa mekhoa e fapaneng ea ho sebetsana le li-twin-screw micro-compounder.Phello ea li-MWNTs boitšoarong ba crystallization ea PP phase le PA6 phase ea motsoako e 'nile ea fuputsoa ka lithuto tsa non-isothermal crystallization ka tlhahlobo e fapaneng ea lik'halorimetric.Ho feta moo, phello ea tlatsetso ea kompatibilizer (PP-g-MA) le phetoho ea MWNTs (m-MWNTs) le non-covalent organic modifier (Li-letsoai la 6 amino hexanoic acid, Li-AHA) le eona e na le e ithutoe maemong a boits'oaro ba kristallise ea karolo ea PP le PA6 molemong oa motsoako.Lithuto tsa crystallization li bonts'itse keketseho e kholo ea mocheso o mongata oa crystallization oa karolo ea PP motsoakong boteng ba MWNTs.Ho feta moo, ho theoa ha sebopeho sa 'trans-lamellar crystalline' se nang le PA6 'trans-crystalline lamellae' holim'a MWNTs se ile sa nolofalloa molemong oa metsoako e lokisitsoeng ka 'protocol 2' ha e bapisoa le metsoako e tsamaellanang e lokisitsoeng ka 'protocol 1' .Tlhahlobo e pharaletseng ea X-ray e fapaneng e bontšitse hore ho na le β-polymorph ea PP phase ka lebaka la ho kenngoa ha karolo ea PA6 ho motsoako.Keketso ea li-MWNT metsoakong e nolofalelitse ho ntlafatsoa ha sebopeho sa β-crystalline sa mokhahlelo oa PP.Boteng ba m-MWNTs, karolo e holimo ea β e ile ea bonoa karolong ea PP ha e bapisoa le motsoako le li-MWNT tse sa tloaelehang.Ho eketsoa ha PP-g-MA ho hatelletse sebopeho sa β-phase karolong ea PP ka har'a motsoako.Tlhahlobo ea sebopeho sa X-ray e senotse hore ho kenyeletsoa ha PA6 hammoho le li-MWNT tsa khale/tse fetotsoeng li susumelitse boholo ba liketane tsa PP mabapi le lifofane tse khethehileng tsa kristale mefuteng e fapaneng ea motsoako oa PP le PA6.
