Rational Control of Polymer Glass Formation and Mechanical Properties with Molecular Additives (PPT)Lots of new possibilities in 'old' diluents. Large (16 category!) design space-plasticizer/antiplasticizer not enough. Relative molecular stiffness of polymer and diluent plays a key role. Also ...
This paper is an investigation on the thermo-mechanical properties of a new class of materials, which holds promise for its potential use as solid polymer electrolytes, i.e., SPE material. A series of poly(ethylene oxide)-polyurethane/poly(acrylonitrile) (PEO-PU/PAN) semi-IPNs, along with ...

obstacles to the broader adoption of sustainable polymer materials. Here, the authors show that co-assembly of oligopeptide-based polymer end groups and a corresponding low molar mass additive leads to a hierarchical structure, resulting in materials with improved processability and mechanical properties....
Biocomposites of poly(lactic acid) (PLA) and pectin, which are low-cost organic materials, were prepared using an internal mixing machine in various pectin contents, i.e., 2, 4, 6 and 8% w/w. When pectin was added as a nucleating agent, the mechanical properties of the biocomposites, ...
Tests of pieces with stress concentrators Stress concentration coefficient ac ?max is the maximum axial stress; ? is the nominal or average stress in the notch section ?c is independent of material’s properties. Stress distribution of a large plate Stress distribution for notched cylindrical ...
