Morphologies and Thermal Variability of Patterned Polymer Films with Poly(styrene-co-maleic anhydride) [PDF]

Polymers, 2014
Patterned films of poly(styrene-co-maleic anhydride) copolymers were deposited by dip-coating from acetone solutions. A qualitative study of the film morphologies shows the formation of polymer spheres with smaller diameters at higher amounts of maleic anhydride (MA), and long-fibrous features at higher molecular weights.

ABS composites with cellulose fibers: Towards fiber-matrix adhesion without surface modification

Composites Part C: Open Access, 2021
Aiming for a cost-effective and environmentally friendly material, we propose the replacement of glass fiber/poly(acrylonitrile-co-butadiene-co-styrene) (ABS) composites by composites with cellulosic reinforcing agents.

Wettability of Amino Acid-Functionalized PSMA Electrospun Fibers for the Modulated Release of Active Agents and Its Effect on Their Bioactivity

Pharmaceutics, 2023
The ideal treatment for chronic wounds is based on the use of bioactive dressings capable of releasing active agents. However, the control of the rate at which these active agents are released is still a challenge.

Compatibility, Morphology, Mechanical Properties and Biodegradability of Poly(styrene-ethylene-propylenestyrene)/ Modified Thermoplastic Starch Blends [PDF]

علوم و تکنولوژی پلیمر, 2016
The effect of modified starch on the properties of poly(styrene-ethylenepropylene- styrene) tri-block copolymer was studied. Chemical treatment of starch with maleic anhydride was accomplished in an internal mixer in the presence of glycerol.
