cross linking of high density polyethylene (hdpe) was first performed via high energy10 mev electron beam (eb) irradiation. hdpe was also cross linked withdicumyle peroxide (dcp).the gel content of samples was determined by solvent extraction.degree of cross linking was evaluated by hot set apparatus; as well .in order to clarify the effectof nature of cross linking, correlation of electrical p...

The objective of this work was to investigate the influence of hydrogen bonds between fibres on static and dynamic strength properties of paper. A commercial bleached pinewood kraft pulp was soaked in water, refined in a PFI, and used to form paper webs in different solvents, such as water, methanol, ethanol, n-propanol and n-butanol, to determine the effect of their dipole moment on static and...

For electrode stability and the electrochemical performance of Li-ion cell, it is essential that active ingredients unique additives in polymer binder be well dispersed with solvent-based slurry. The efficient procedure used to create slurry affects rheological characteristics When successively adding different steps N-methyl-2-pyrrolidone (NMP) solvent cathode composition, evenly disseminated....

In this work, we experimentally investigate into one step solvent exchange of cylindrical shaped whey protein isolate (WPI) gels, where the pore fluid water inside pores is replaced by ethanol. Solvent has three major impacts on macroscopic gel properties, leading to an increase in compressive strength, shrinkage cylinders diameter and consequently a change spatial distribution. 1D-Raman spectr...

Surfactant-free emulsion polymerization involving a nonionic, and hence uncharged initiator presents a new approach towards environmentally friendly procedures to synthesize latex particles. Under optimal solvent conditions, notably pH and ionic strength, the latex particles are stabilized by the natural development of ionic charge at the surface of the particles. We emphasize that the present ...

Fluorinated denture base acrylic resins can present more stable physical properties when compared with conventional polymers. This study evaluated the incorporation of a fluoroalkyl methacrylate (FMA) mixture in a denture base material and its effect on roughness and flexural strength. A swelling behavior assessment of acrylic resin specimens (n=3, per substance) after 12 h of FMA or methyl met...

• Fungal and shrimp chitosan were wet spun to monofilament yarns. Using adipic acid as solvent generally resulted in fibers with higher tensile strength compared obtained using lactic acid. Chitosan monofilaments showed a similar or better biocompatibility commercial sutures. are good candidates for being used Purified fungal crustacean by acids solvent. The lowest viscosity at which fiber form...
