“…This occurs even in polymers expected to have ductile behaviour such as polycarbonate [3,4] and PET [5e7]. In a pioneer work [8], Howard defined ESC as a brittle failure that is initiated at the surface of a polymer product that is under, simultaneously, a stress field and an aggressive fluid.…”

In this study, the environmental stress cracking (ESC) resistance of nano-SiO 2 particle-filled polycarbonate (PC) was investigated at room temperature by using a fracture mechanical test method. Two PC-based nanocomposites with nano-SiO 2 content of 1 and 4 vol% were compounded using a twin-screw extruder. The incorporation of nanoparticles into PC leads to an improvement in ESC resistance, which increases with increased filler loading up to 4 vol%. Fractography analyses suggest that the formation of cavities/debonding and localized microdeformation of matrix induced by nanoparticles as a result of energy dissipation are responsible for the improvement of ESC resistance.

“…In 1996, a baby was fed via a Hickman line and suffered an infection, when new connectors were used by a hospital. 31 The reason behind this infection was the cracking and erosion of the pipes from the inner side due to contact with liquid media. It was reported that the baby suffered from brain damage and later the mother decided to le a legal case of medical negligence (usage of inappropriate medical device) in 2002.…”

The degradation of mechanical properties in polymer nano-composites exposed to liquid media – a review

The advancement of polymer nano-composites has been motivated by the need for materials with a specific combination of mechanical properties beyond those achieved from only one material.Integration of reinforcement into polymers at the nanoscale can provide a significant increase in numerous physical and mechanical properties of polymer nano-composites. However, in applications where contact with liquid media is unavoidable, the mechanical properties of polymer nano-composites suffer degradation which is a commonly observed phenomenon. Non aggressive liquid such as water is capable of lowering the mechanical properties of polymer nano-composites by acting as plasticizers while moderate and severe aggressive liquid when combined with residual stresses can cause unexpected brittle failure known as ESC. To date, only a few studies are reported discussing the ability of nano-fillers to resist degradation of mechanical properties in polymer nano-composites when exposed to liquid media. In this review, various factors responsible for mechanical property degradation caused by liquid media in polymer nano-composites and their remedies are studied.
