“…It was widely accepted that the fiber interface is generally enriched of low molecular weight chains of the same polymer, though evidenced considerably later [106]. Better wetting of the reinforcing fibers by amorphous rather than by crystallizable microstructures of the same polymer was also reported [107,108].…”

This review summarizes the recent (from year 2000) advancements in the interphase tailoring of fiber-reinforced polymer composites. The scientific and technological achievements are classified on the basis of the selected strategies distinguishing between i) interphase tailoring via sizing/coating on fibers, ii) creation of hierarchical fibers by nanostructures, iii) fiber surface modifications by polymer deposition and iv) potential effects of matrix modifications on the interphase formation. Special attention was paid to report on efforts dedicated to the creation on (multi)functional interphase in polymer composites. This review is round up by listing current trends in the characterization and modelling of the interphase. In the final outlook, future opportunities and challenges in the engineering of fiber/matrix interphase are summarized.

“…Additionally, it has already been evidenced that preferred wetting of CNTs or carbon fibers by PS of lower molecular weight compared to high molecular weight polymer takes place . This preference is due to the lower surface tension of low molecular weight fractions of a given type of molten polymer compared to higher molecular weight material .…”

Electrically conductive composites consisting of carbon nanotubes (CNTs) in a poly(2,6-dimethyl-1,4-phenylene ether)/polystyrene (PPE/PS) blend are prepared by latex technology. The latter consists of 4 steps: preparation of an aqueous dispersion of CNTs, mixing with a polymer latex, solvent removal by freeze-drying and processing. In the first route, PPE/PS blend latexes are directly used to prepare nanocomposites by latex technology. The CNT/PPE/PS composites display an increased glass transition temperature compared to unfilled material and a percolation threshold as low as 0.3 wt% of CNTs. Secondly, CNT/PS masterbatches prepared by latex technology are mixed with PS/PPE blend pellets by extrusion. This approach constitutes a potential first step towards an industrially viable process.

“…The difference between unfilled and filled elastomers may be explained within the concept of preferential segregation for polymer chains in the vicinity of filler particles, see, e.g., [4]. According to this approach, during the composite processing, short chains are segregated to interfaces between the elastomeric matrix and particles, whereas the concentration of long chains in the host material is increased.…”
