Phase identification and the study of the interphase region in multi-component polymer blends with a chemically similar structure using conventional techniques is a challenge. In this work, the detailed morphological analysis of such systems is examined. A ternary blend comprised of poly butylene succinate (PBS); poly lactic acid (PLA); and polycaprolactone (PCL) with a partial wetting morphology...
In this study, it will be shown that morphologically tailored tricontinuous ternary blends, comprising polybutylene succinate (PBS), polylactic acid (PLA), and poly (butylene adipate‐co‐terephthalate)(PBAT), can generate new materials with excellent properties. Detailed morphological analysis is used to establish that all three phases in the ternary 33%PBS/33%PLA/33%PBAT blend morphology are highly...
The coarsening of polymer mixtures is an important route towards major morphology modification in multiphase polymer systems. To date however the coarsening of ternary systems has not been significantly examined. In this study the phase coarsening mechanism via annealing for partial wetting, and complete wetting morphologies in ternary polymer blends is characterized. This is a route towards the examination...
Poly(butylene succinate) (PBS) is a promising polymer for the production of bio-based and biodegradable materials. This study focuses on the development of novel tunable morphological states based on ternary blends comprising PBS. The other biodegradable polymers are selected from a set of poly(lactic acid) (PLA), poly(butylene adipate-co-terephthalate) (PBAT), and polycaprolactone(PCL). Three completely...
In this work a 3D porous polymeric conducting material is derived from a multi-percolated polymer blend system. The work has focused on the preparation of low surface area porous substrates from polymer blends followed by the deposition of polyaniline conductive polymer (PANI) on the internal porous surface using a layer-by-layer (LbL) technique. The approach reported here allows for the percolation...
For the most part, ternary polymer blends demonstrate complete wetting behavior. Conceptually, this is the state where one of the components will always tend to completely separate the other two and from a thermodynamic viewpoint is described as the case where two of the three possible binary spreading coefficients are negative and the other is positive, as defined by Harkins spreading theory. This...
In this work we report on the preparation of a solid, 3D, low percolation threshold conductive device prepared through the control of multiple encapsulation and multiple percolation effects in a 5 component polymer blend system through melt processing. Conductive polyaniline (PANI) is situated in the core of the 5 component continuous system comprised of high-density polyethylene (HDPE), polystyrene...
