Strong synergistic improvement of mechanical properties in HDPE/COC blends with fibrillar morphology

Ostafinska, Aleksandra; Vackova, Tatana; Slouf, Miroslav

High-density polyethylene/cycloolefin copolymer (HDPE/COC) blends with fibrous morphology were prepared. Mechanical properties in the whole concentration range were measured in both macroscale (tensile measurements) and microscale (microindentation hardness testing). Strong improvement of mechanical performance was observed namely for the blends with soft HDPE matrix reinforced with the stiff…

Amino-functionalized breath-figure cavities in polystyrene–alumina hybrid films: effect of particle concentration and dispersion

V, Lakshmi; Raju, Annu; G, Resmi V.; Pancrecious, Jerin K.; D, Rajan T. P.; C, Pavithran

We report the formation of breath-figure (BF) patterns with amino-functionalized cavities in a BF incompatible polystyrene (PS) by incorporating functionalized alumina nanoparticles. The particles were amphiphilic-modified and the modifier ratio was regulated to achieve a specific hydrophobic/hydrophilic balance of the particles. The influence of the physical and chemical properties of…
