“…However, most of the polymer blends are found to be incompatible. [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19] These incompatible polymer blends have poor mechanical and physical properties. In order to improve the mechanical properties of the polymer blends, the compatibilizer has been widely used.…”

The effects of maleic anhydride-grafted polypropylene (PP-g-MAH) addition on polypropylene (PP) and poly(acrylonitrile-butadiene-styrene) (ABS) blends were studied. Blends of PP/ABS (70/30, wt%) with PP-g-MAH were prepared by a twin-screw extruder. From the results of mechanical testing, the impact, tensile and flexural strengths of the blends were maximized at a PP-g-MAH content 3 phr. The increased mechanical strength of the blends with the PP-g-MAH addition was attributed to the compatibilizing effect of the PP and ABS blends. In the morphological studies, the droplet size of ABS was minimized (6.6 μm) at a PP-g-MAH content of 3 phr. From the rheological examination, the complex viscosity was maximized at a PP-g-MAH content of 3 phr. These mechanical, morphological and rheological results indicated that the compatibility of the PP/ABS (70/30) blends is increased with PP-g-MAH addition to an optimum blend at a PP-g-MAH content of 3 phr.

“…Hydrogels are important materials for biomedical applications because they possess hydrophilicity and a degree of flexibility very similar to that of natural tissue due to their significant water content. For these reasons, polymeric hydrogels have been used as scaffolds in tissue engineering, [13][14][15] sustained-release drug carriers, [16][17][18] biosensors, 19,20 and contact lenses. 21,22 Alginate is probably one of the most frequently studied hydrogel-forming polymers.…”

This study reports the preparation and characterization of nanohydrogels by using sodium alginate as a model material. Alginate nanohydrogels (ANH) were prepared by emulsification-diffusion method in a w/o system with 1,2-diacyl-sn-glycero-3-phosphocholin as the lipophilic surfactant. The effects of the alginate to surfactant ratio and the remaining water contents on the mean particle size and swellability of ANHs were investigated in terms of the concentration, agitation speed, and agitation time. The feasibility of using nanohydrogels and their controllability were proved by the water the absorbency of ANHs during a 7-day evaluation by dynamic light scattering. In this work, the mean particle sizes of ANHs could be controlled from 49.2 nm (measured in ethanol phase) to 1.9 μm (measured in water phase, after 7 days of water absorption).

In this study, unsaturated polyester resin (UPE) and Natural rubber (NR) were used to prepared binary polymer blend (UPE/ NR) with weight ratio (95/5) %. The present paper investigates the diffusion behavior of three environmental groups , the first group is different types of water included (distilled water, tap water, rain water), the second is diluted solutions with same concentration (HCl , H2SO4, NaCl) and the third is solvents (ethanol, kerosene, benzene) and study their effects through (UPE/NR) polymer blend. Consequently, a set of specimens were immersed in various types of water, solutions and solvents for different periods of time. The diffusion coefficients (Dx) of these liquids were calculated based on Fick's law. The results of a series of experimental investigations showed that the values of (Dx) of all liquids are in the range (3.95-9.1 *10 -12 m 2 /s) except benzene which behaves another behavior called (non-Fickian diffusion) through the same time of immersion.
