Abstract
This work aims to prepare biodegradable poly (butylene adipate-co-terephthalate) (PBAT)/thermoplastic polyamide elastomer (TPAE) foam with excellent mechanical properties after blending and chain extension. The results showed that the introduction of TPAE increased the foaming temperature of the PBAT/TPAE blend foams, improved the foaming performance, reduced the shrinkage, and enhanced the compressive stress. The stable expansion ratio of PBAT/TPAE10 increased to 15.2 at 110 ℃, and the shrinkage ratio just reached 54.9 %. The energy loss coefficient of PBAT/TPAE at a high expansion ratio of 10 is 7.8 %. The resilience of PBAT/TPAE20 reached 61.3 % at an expansion ratio of 14.
期刊介绍:
The Journal of Supercritical Fluids is an international journal devoted to the fundamental and applied aspects of supercritical fluids and processes. Its aim is to provide a focused platform for academic and industrial researchers to report their findings and to have ready access to the advances in this rapidly growing field. Its coverage is multidisciplinary and includes both basic and applied topics.
Thermodynamics and phase equilibria, reaction kinetics and rate processes, thermal and transport properties, and all topics related to processing such as separations (extraction, fractionation, purification, chromatography) nucleation and impregnation are within the scope. Accounts of specific engineering applications such as those encountered in food, fuel, natural products, minerals, pharmaceuticals and polymer industries are included. Topics related to high pressure equipment design, analytical techniques, sensors, and process control methodologies are also within the scope of the journal.
