Because of negligible contributions of combinatorial entropy, miscibility of polymers is attributed predominantly to favorable (exothermic) enthalpic effects of mixing, i.e., to strong interactions between the blend components, which have to overcome the cohesive forces acting within the components. Miscibility of amorphous polymers usually is associated with the presence of a single glass temp...

Isothermal and non-isothermal crystallization behaviours of the blends of long chain branched polypropylene (LCB PP) and poly(ethylene-co-octene) (PEOc) with different weight ratios were studied under quiescent and shear flow using polarized optical microscopy (POM), differential scanning calorimetry (DSC), and rheological measurements. Experimental results showed that the crystallization of th...

The optimal physical, chemical and nutritional properties of natural lipids depend on the structure and composition of triacylglycerols. However, they are not always mutually compatible. Lipid modification is a good way to give them specific functionalities, increase their oxidative stability, or improve their nutritional value. As such, chemical and enzymatic interesterification may be used to...

We report the electrical and optical properties of two-component blends of electron and hole transporting materials in single and bilayer structures for organic light emitting diode ~OLED! applications. The materials considered were a blue-emitting bipolar transporting polyfluorene, poly~9,9-di-n-hexylfluorene! ~DHF!, and a hole-transporting material, poly-@4-nhexyltriphenylamine# ~HTPA!. We co...

Quantification of elastomer content for the ethylene-propylene diene monomer/polybutadiene blend are seldom subjects in literature, mainly due to rubber compatibility problems. However, suitable contents can lead desirable properties. Infrared spectroscopy quantify this type even if some bands overlap, which be resolved with proper choice spectrum obtaining mode and non-overlapping analytical b...

We show that a new type of hydrogel can be prepared by covalently inter-linking binary blends of microgel (MG) particles and that the swelling ratio and modulus of the gels can be predicted from their composition. In previous work we established that physical gels of glycidyl methacrylate (GMA) functionalised poly(methyl methacrylate-co-methacrylic acid-co-ethyleneglycol dimethacrylate) microge...

In recent years, a wide range of different methods to implant nanosized patterns on surfaces have been developed. Spin coating immiscible binary polymer blends is a straightforward method to prepare micro- and nanostructures on thin films. This study utilizes binary blends to effortlessly prepare stable, surface-functionalized cellulose films. Blends of trimethylsilyl cellulose (TMSC) majority ...
