Nanoskalali to'ldiruvchilar bilan mustahkamlangan polimer kompozit materiallar, ishqalanish, namlik, harorat o'zgarishlari va dinamik yuklanish sharoitida ishlaydigan an'anaviy metall komponentlarni almashtirish qobiliyati tufayli mexanik muhandislikda tobora ko'proq qo'llanilmoqda. Poliamid-6 (PA6) yuqori kuch, elastiklik va aşınma qarshiligi tufayli eng istiqbolli polimer matritsalaridan biridir. Biroq, uning amaliy qo'llanilishi past qattiqlik, termal kengayish va o'lchov barqarorligi bilan cheklangan. Ushbu tadqiqotda PA6 matritsasiga temir oksidi (FeO) nanopartikullari kiritilib, ularning polimerning strukturaviy tashkilotiga ta'siri infraqizil (IR) spektroskopiyasi yordamida o'rganildi. Maqsad - PA6 ning aromatik va alifatik strukturaviy fragmentlari bilan FeO nanopartikullari o'rtasidagi o'zaro ta'sirlar supramolekulyar tartib va vodorod bog'lanishlariga qanday ta'sir qilishi ekanligini baholashdir. IR spektral tahlili Amide I, II, III, V va VI ning xos bandlarida siljishlar va intensivlik o'zgarishlarini ko'rsatdi, bu vodorod bog'lanishlarining buzilishi va qayta taqsimlanishini hamda makromolekulyar tarmoqning qisman qayta tashkil etilishini ko'rsatadi. 823, 886 va 1503 sm⁻¹ da qo'shimcha piklarning paydo bo'lishi va 700 va 600 sm⁻¹ da bandlarning birlashishi yoki siljishi yangi o'zaro ta'sirlar, jumladan imid, immoniy va karboksilatga oid tuzilmalarni shakllanishini ko'rsatdi. FeO miqdori 40 vazn foizgacha bo'lganida, sezilarli amorfizatsiya yoki γ-modifikatsiyaga o'tish kuzatildi. Ayrim C–N tebranish piklarining yo'qolishi to'ldiruvchi va polimer o'rtasidagi molekulyar darajadagi o'zaro ta'sir jarayonlarini, vodorod bog'lanishlari naqshlari va elektrostatik assotsiatsiyalaridagi o'zgarishlar bilan birga kelayotgan dekitsiklizatsiya jarayonlarini ko'rsatdi. Natijalar shuni tasdiqlaydi ki, FeO nanopartikullari PA6 kompozitlarida strukturaviy tartibni boshqaruvchi rol o'ynaydi va mexanik muhandislik ilovalari uchun fizik-kimyoviy va tribologik xususiyatlarni maqsadli modifikatsiya qilishda foydalanilishi mumkin.
