TLDR
In this paper, the behavior of poly(lactic acid), PLA, and poly(e-caprolactone), PCL, is investigated by means of a video-controlled materials testing system specially developed to assess true stress vs. true strain curves and to record the volume changes upon stretching.About:

Selective Localization of Multiwalled Carbon Nanotubes in Poly(ε-caprolactone)/Polylactide Blend
TL;DR: Owing to that unique selective interface-localization and improved phase morphology, the ternary composites present far lower rheological and conductive percolation thresholds than those of the binary composites, and also present extraordinary mechanical properties even at very low loading levels of the MWCNTs.

Biomedical Magnesium Alloys: A review of material properties, surface modifications and potential as a biodegradable orthopaedic implant
TL;DR: In this article, a review of the properties, chemical stability, degradation in situ and methods of improving the corrosion resistance of magnesium and its alloys for potential application in the orthopaedic field is presented.
Journal ArticleDOI
Cavitation during deformation of semicrystalline polymers
TL;DR: In this article, the cavitation phenomenon is observed during deformation in many semicrystalline polymers above their glass transition temperature, which is observed only in tension, never during compression or shearing.

Poly(lactic acid): plasticization and properties of biodegradable multiphase systems
O Martin,Luc Avérous +1 more
TL;DR: In this paper, thermoplastic starch (TPS) and poly(lactic acid) (PLA) were combined with polyethylene glycol and oligomeric lactic acid (OLA) to obtain a significant decrease in glass transition temperature (Tg) shift and mechanical properties improvement.

Large-scale production, properties and commercial applications of polylactic acid polymers
TL;DR: In this paper, the authors discuss the various technologies being used to produce polylactic acids and how monomer stereochemistry can be controlled to impart targeted utility in the final polymers.

Crystal structure, conformation and morphology of solution-spun poly(L-lactide) fibers
TL;DR: In this article, two crystal structures for solution-spun poly(L-lactide) are obtained: the pseudoorthorhombic α structure (a = 10.6, b = 6.1, and c = 28.8 A) is found at relatively low drawing temperatures and/or low hot-draw ratios.

Effects of morphology, conformation and configuration on the IR and Raman spectra of various poly(lactic acid)s
TL;DR: In this article, a series of aliphatic polyesters of the polylactide-type were studied by 13 C n.m. and vibrational spectroscopies, where fundamental vibrations were correlated to bands characterising morphology, conformation and configuration of these different polymers.

Properties of thermoplastic blends: starch-polycaprolactone
TL;DR: In this article, different compositions of wheat thermoplastic starch (TPS) and polycaprolactone (PCL) are melt blended by extrusion and injected, and different properties are determined: mechanical properties (tensile and impact tests), thermal and thermomechanical properties (DSC and DMTA) and hydrophobicity (contact angle measurement).
