Ua hoʻomākaukau ʻia ka hui ʻana o ka polypropylene (PP) a me ka polyamide 6 (PA6) me nā nanotubes kalapona multiwalled (MWNTs) me ka hoʻohana ʻana i nā hoʻolālā hana ʻokoʻa i loko o kahi micro-compounder twin-screw.Ua noiʻi ʻia ka hopena o nā MWNT ma ke ʻano crystallization o ka pae PP a me ka pae PA6 o ka hui ʻana ma o nā haʻawina crystallization non-isothermal e ka nānā ʻana i ka calorimetric scanning differential.Eia kekahi, ʻo ka hopena o ka hoʻohui o ka compatibilizer (PP-g-MA) a me ka hoʻololi ʻana o MWNTs (m-MWNTs) me kahi mea hoʻololi organik non-covalent (Li-paʻakai o 6 amino hexanoic acid, Li-AHA) ua loaʻa pū kekahi. ua aʻo ʻia ma ka pōʻaiapili i ka ʻano crystallization o ka pae PP a me PA6 i ka hui.Ua hōʻike nā haʻawina crystallization i ka piʻi nui ʻana o ka nui crystallization wela o ka māhele PP i ka hui ʻana i mua o nā MWNT.Eia kekahi, ua maʻalahi ka hoʻokumu ʻia ʻana o ka 'trans-lamellar crystalline' me ka PA6 'trans-crystalline lamellae' ma ka ʻili o MWNTs i ka hihia o ka hui ʻana i hoʻomākaukau ʻia ma o 'protocol 2' i hoʻohālikelike ʻia me nā hui like i hoʻomākaukau ʻia ma o 'protocol 1'. .Ua hōʻike ʻia ke ʻano o ka β-polymorph o ka māhele PP ma muli o ka hoʻohui ʻana o ka pae PA6 i ka hui ʻana.ʻO ka hoʻohui ʻana o nā MWNT i loko o ka hui ʻana ua hoʻomaʻamaʻa hou i ka hoʻokumu ʻana o ka β-crystalline structure o ka pae PP.Ma ke alo o nā m-MWNT, ua ʻike ʻia kahi hapa β kiʻekiʻe ma ka pae PP i hoʻohālikelike ʻia me ka hui ʻana me nā MWNT maʻemaʻe.ʻO ka hoʻohui ʻana o PP-g-MA ua kāohi i ka hoʻokumu ʻana o ka β-phase i ka pae PP i ka hui ʻana.Ua hōʻike ʻia ka hoʻopili ʻana o PA6 a me nā MWNT maʻemaʻe/hoʻololi ʻia i ka nui o ka hoʻonohonoho ʻana o nā kaulahao PP i nā mokulele crystalline kikoʻī ma nā ʻano hui like ʻole o PP a me PA6.
