    The impact of short glycol structure on the structure and properties of polyurethanes is studied by analyzing the influence of the primary (chain conformation) and secondary structures (amorphous and crystalline phases) on the crystallinity and mechanical properties of high urethane density polymers based on aliphatic 1,6-hexamethylene diisocyanate. This provides insight into the role of segmental architecture influence on the self-assembling and mechanical performance of high urethane density polyurethanes.

    A composite cryogel that produces high strength composites materials which can control the release of antimicrobial agents is the aim of this work. The constructs presents stronger values than similar materials in the literature and contain porous structure which is beneficial for vascular invasion and bone ingrowth. Since the fabrication method does not require any toxic elements, presents good biocompatibility and ability to control swelling, this system have great potential in the field of orthopaedics.

  3. Controlled dispersion of polystyrene-capped Au nanoparticles in P3HT:PC61BM and consequences upon active layer nanostructure

    Au nanoparticles with a polymer coating assemble into three-dimensional ordered structures, dependent upon processing conditions, which impact film structure and the electronic and optical properties when placed into an organic photovoltaic active layer. The accompanying figure provides a three-dimensional reconstruction of polymer coated Au nanoparticles within the active layer of an organic photovoltaic active layer film.

  4. Effect of constrained annealing on the mechanical properties of electrospun poly(ethylene oxide) webs containing multiwalled carbon nanotubes

    Annealing near Tm under a minor constraint (the presence of paper frame) leads to fiber alignment which resulted in significant increases in modulus as the fibers, the aligned molecules within them, and well-dispersed MWNT if present became oriented along the tension axis. In particular, constrained annealing at temperatures just below the melting point resulted in fiber alignment due to the imposed tension when the mat was unable to spontaneously shrink.

  5. Revisiting the crystallization of poly(2-alkyl-2-oxazoline)s

    Differential scanning calorimetry is used to investigate the crystallization of poly(2-alkyl-2-oxazoline)s as a function of alkyl side chain length. Different crystallization behaviors—no, cold, and normal crystallization—are observed and attributed to different polymer chain mobility, in line with the Tg dependence of alkyl side chain length. The decrease in chain mobility with decreasing alkyl side chain length results in double melting peaks in PButOx.
