CNT-Filled Polypropylene/Plasticized Polyvinyl Alcohol Mixtures: Rheology, Morphology, and Properties of Composite Threads
0349–0361 (2023)

PACS numbers: 61.41.+e, 61.48.De, 62.23.Pq, 66.20.Ej, 81.05.Lg, 82.35.Np, 83.80.Sg

The influence of the concentration of plasticizer (glycerine) and carbon nanotubes (CNTs) on the micro- and macrorheological properties of melts of polypropylene/plasticized polyvinyl alcohol (PP/PVA) mixtures is studied. During flow of melts of all the studied compositions, a microfibrillar structure is formed within them. As found, changing the ratio of viscoelastic properties of PP and PVA, when adding different amounts of modifying additives, allows us to adjust the mass fraction of types of structures (microfibrils, films, particles), as well as their dimensional characteristics. Reducing the average diameter of microfibrils from 2.7 to 1.2 μm and increasing their share from 84.3 to 96.8 wt.% in the initial and nanofilled mixtures, respectively, are achieved in a composition with similar values of viscosity and elasticity of the components. As shown, the melts of bi- and three-component systems are typical non-Newtonian fluids, and the viscosity of their melts is several times lower than η of the initial components. The values of elasticity, judging by the equilibrium swelling of extrudates, are higher than for the starting polymers, and depend on the content of nanotubes. The ability to longitudinal deformation of the melt jet, which determines its fibre-forming properties, in composite systems is reduced, but remains sufficient for stable processing into threads on available process equipment. As established, the formed microfibrillary structure helps to improve the performance characteristics of composite monothreads due to the effect of self-reinforcement. Tensile strength and dimensional stability of threads obtained from a mixture containing 0.5 wt.% CNTs increase by 1.5 and 1.6 times, respectively.

Key words: polypropylene, polyvinyl alcohol, glycerine, carbon nanotubes, mixtures, morphology, monothreads, viscosity.
