Polypropylene‐based nanocomposite with improved mechanical properties: Effect of cellulose nanofiber and polyrotaxane with partial miscibility

The mechanical properties and miscibility of polymer-based composites containing cellulose nanofiber (CNF) polyrotaxane (p-rtx) as organic fillers were studied in detail. CNF p-rtx introduced powders into a polypropylene (PP) matrix, prepared using simple melt-compounding method. best achieved when loaded at concentration 0.6 wt%. Young's modulus the composite increased by 760 MPa compared with that PP matrix. In addition, presence mica promoted epitaxial growth along (1 3 0) plane. various shifts melting/crystallization temperatures different CNF:p-rtx ratios confirmed partial between enhancement is believed to be due surfaces aggregates uniform dispersion
