“…Our previous work 38,39 showed that the fillers or additives can be forcedly distributed in the continuous and parallel layered space of polymer matrix through microlayered coextrusion technology to obtain various composites with excellent properties. Baer et al studied the confined crystallization of PP in multilayer films employing this technology.…”

The β-nucleated polypropylene (β-PP) and polypropylene (PP) were coextruded to form the alternating layered structure with different layer number. During the isothermal crystallization of layered samples at 130°C, the high-density β-nuclei at the two-dimensional layered interfaces between β-PP and PP layers grew asymmetrically. In the β-PP layer, the growth of β-lamellae was quickly terminated by other β-spherulites. In the PP layer, because the formation of α-crystals delayed, all β-lamellae could freely grow perpendicular to the interface and finally form the β-transcrystallinity (β-TC) layer with about 25 μm thickness. If the thickness of PP layer was lower than 50 μm, PP layer would be almost occupied by β-TC. The ordered arrangement of β-TC led to an orientation of molecular chains of β-TC layer parallel to the interface. With the increase of layer number, the content of β-TC and orientation degree of layered samples increased. This paper provided a simple and effective method to prepare continuous, highly ordered and content-controlled β-TC. As a result, the sample with high content of β-TC exhibited good mechanical properties.

NiP alloycarbon black (CB) composite films were fabricated by electroplating and their microstructures and properties were examined. The CB and phosphorus contents of the composite films were also investigated. The CB particles were found to be embedded in the NiP alloy matrix. The CB content in the deposits increased, reached a maximum value of 0.77 mass % with increasing CB concentration in the bath up to 10 g dm 3 , and then decreased with a further increase in the CB concentration in the bath.Both before and after heat treatment, the composite films had higher hardnesses and lower friction coefficients than the NiP alloy films. Both before and after heat treatment, the friction coefficient of 0.77 mass % CB composite films was about half that of NiP alloy films without CB.
