Uruvange rwa polypropilene (PP) na polyamide 6 (PA6) hamwe na nanotubes ya karubone nyinshi (MWNTs) byateguwe hifashishijwe ingamba zitandukanye zo gutunganya mikorobe ikomatanya.Ingaruka za MWNTs ku myitwarire ya kristalisation yicyiciro cya PP nicyiciro cya PA6 cyuruvange rwakozweho ubushakashatsi hakoreshejwe ubushakashatsi butari isothermal kristalisation hakoreshejwe isesengura rya skaneri ya calorimetric.Ikigeretse kuri ibyo, ingaruka zo kongeramo imashini (PP-g-MA) no guhindura MWNTs (m-MWNTs) hamwe na modifike kidahinduka (Li-umunyu wa aside amine 6 ya hexanoic, Li-AHA) nayo ifite byizwe mubijyanye nimyitwarire ya kristalisation yicyiciro cya PP na PA6 muruvange.Ubushakashatsi bwa kristallisation bwerekanye ubwiyongere bugaragara bwubushyuhe bwinshi bwa kristalisation yicyiciro cya PP muruvange imbere ya MWNTs.Byongeye kandi, gushiraho 'trans-lamellar crystalline' igizwe na PA6 'trans-crystalline lamellae' hejuru ya MWNTs byorohewe mugihe habaye imvange zateguwe binyuze kuri 'protocole 2' ugereranije nuruvange ruhuye rwateguwe hakoreshejwe 'protocole 1'. .Isesengura ryagutse X-ray itandukanya ryerekanye ko hariho β-polymorph yicyiciro cya PP kubera kwinjiza icyiciro cya PA6 mukuvanga.Kwiyongera kwa MWNTs muruvange byoroheje kurushaho β-kristaline imiterere yo gushiraho icyiciro cya PP.Imbere ya m-MWNTs, igice kinini β -igice cyagaragaye mugice cya PP ugereranije no kuvanga na MWNT nziza.Kwiyongera kwa PP-g-MA byahagaritse formation -cyiciro cyo gushinga icyiciro cya PP mubuvange.Isesengura ryinshi rya X-ray ryerekanye ko kwinjiza PA6 kimwe na MWNT ya pristine / yahinduwe byagize ingaruka ku cyerekezo cy’iminyururu ya PP yerekeza ku ndege yihariye ya kirisiti mu bice bitandukanye bigize PP na PA6.
