Realizing the enhancement of interfacial interaction in semicrystalline polymer/filler composites via interfacial crystallization

A review on the role of interface in mechanical, thermal, and electrical properties of polymer composites

“…In this process, the fillers will act as a nuclei and the semi-crystalline host will crystallize at the interface [64].…”

Correlation between degree of crystallinity, morphology and mechanical properties of PPS/carbon fiber laminates

“…It is well known that the crystallization process plays a crucial role on the properties of semi-crystalline polymers [12][13][14] and that the presence of carbon fibers as reinforcement may also influence this process [15][16][17] . However, the images obtained by polarized light optical microscopy in this work do not show any evidence of nucleation under the cooling rates performed, when analyzed in the range of 0.5 to 20 °C/min.…”

“…Thus, an increase in crystallization rate and crystallization temperature as well as a decrease in crystal size is generally observed 13 . The crystalline formation at the interphase region depends on a number of factors, such as matrix morphology, substrate surface condition, as well as the presence of reactive functionalities 14 .…”

“…Some fibers may induce crystallization along the polymer/fiber interface due to the high density of active nuclei on its surface, which hinder the full extension of spherulites and force the crystal growth in the perpendicular direction 13 . This particular behavior can results in a columnar crystalline layer, known as transcrystallinity (TC) 15 .…”

“…Since it was first reported, TC has attracted tremendous attention, because it may be an effective and economical method to improve the interfacial adhesion between polymer matrix and fiber. To date, TC has been reported to occur at the interface between several semi-crystalline polymers, such as PPS and PEEK 13 .…”
