Kuphatikizika kwa polypropylene (PP) ndi polyamide 6 (PA6) yokhala ndi ma multiwalled carbon nanotubes (MWNTs) adakonzedwa pogwiritsa ntchito njira zosiyanasiyana zopangira ma twin-screw micro-compounder.Zotsatira za MWNTs pa khalidwe la crystallization la gawo la PP ndi gawo la PA6 la kusakaniza lafufuzidwa kupyolera mu maphunziro osakhala ndi isothermal crystallization ndi kusanthula kosiyana kwa calorimetric.Kuphatikiza apo, zotsatira za kuwonjezera kwa comptibilizer (PP-g-MA) ndi kusinthidwa kwa MWNTs (m-MWNTs) ndi non-covalent organic modifier (Li-salt wa 6 amino hexanoic acid, Li-AHA) adaphunziridwa molingana ndi mawonekedwe a crystallization a PP ndi PA6 gawo pakuphatikiza.Maphunziro a crystallization awonetsa kuwonjezeka kwakukulu kwa kutentha kwa crystallization ya gawo la PP mu kusakaniza pamaso pa MWNTs.Kuphatikiza apo, mapangidwe a 'trans-lamellar crystalline' opangidwa ndi PA6 'trans-crystalline lamellae' pamtunda wa MWNTs adawongoleredwa chifukwa cha zosakaniza zokonzedwa kudzera mu 'protocol 2' poyerekeza ndi zosakanikirana zomwe zakonzedwa kudzera mu 'protocol 1' .Kusanthula kosiyanasiyana kwa X-ray kwawonetsa kukhalapo kwa β-polymorph ya gawo la PP chifukwa chophatikizira gawo la PA6 muzophatikiza.Kuwonjezedwa kwa MWNT mu zophatikizika kwathandizira kupangidwanso kwa β-crystalline kapangidwe ka gawo la PP.Pamaso pa m-MWNTs, β-fraction yapamwamba idawonedwa mu gawo la PP poyerekeza ndi kuphatikiza ndi ma MWNT apristine.Kuphatikiza kwa PP-g-MA kwapondereza mapangidwe a β-gawo mu gawo la PP muzosakaniza.Kusanthula kawonekedwe ka X-ray kunawonetsa kuti kuphatikizidwa kwa PA6 komanso ma MWNT osasinthika/kusinthidwa kwakhudza momwe ma tcheni a PP amawonera ndege zenizeni zamakristali m'mitundu yosiyanasiyana ya PP ndi PA6.
