摘要: Abstract Poly(ϵ-caprolactone) (PCL) was reinforced with amino-functionalized multi-walled carbon naonotubes ( f- MWCNTs) by an in situ ring opening polymerization (ROP) procedure. Transmission electron microscopy (TEM) initially utilized order to observe the state of dispersion MWCNTs matrix, which is known affect heavily physicochemical properties composite materials. Subsequently, a thorough investigation decomposition profiling PCL and nanocomposites performed employing thermogravimetric analysis (TGA) analytical pyrolysis–gas chromatography/mass spectroscopy (Py–GC/MS). The results from TGA revealed that thermal stability matrix not enhanced MWCNTs, while detailed study Py–GC/MS showed random chain scission via cis -elimination, intramolecular transesterification unzipping reactions dominate PCL. It noteworthy highest amount filler found catalyze without interfering detected mechanisms. In terms mechanical properties, presence improved stiffness as evidenced through dynamic (DMA).
