1. Hydrogels of Poly(vinyl alcohol) and Nanocellulose for Ophthalmic Applications : Synthesis, Characterization, Biocompatibility and Drug Delivery Studies
Sammanfattning : Hydrogels are commonly used materials in ophthalmic care as contact lenses, bandage lenses, corneal implants, and cornea regeneration scaffolds. Hydrogels can be produced by physical, chemical, or radiation crosslinking of hydrophilic polymers. LÄS MER
2. Diffusion in Poly(vinyl alcohol) and Polyethylene as Determined by Computational Simulations and Modeling
Sammanfattning : Poly(vinyl alcohol) and polyethylene polymer systems werebuilt in order to study their transport properties (diffusion).First a verification of the AMBER force field was conducted fora poly(vinyl alcohol) system built from a chain with 145repeating units. NPT-molecular dynamics simulations attemperatures between 400 and 527 K were performed. LÄS MER
3. Transport properties of poly(vinyl alcohol) determined by molecular dynamics simulation
Sammanfattning : .... LÄS MER
4. Poly(vinyl alcohol)-coated papers : effects of surface characteristics of the substrate
Sammanfattning : .... LÄS MER
5. Effects of plasticizing and crosslinking on the mechanical and barrier properties of coatings based on blends of starch and poly(vinyl alcohol)
Sammanfattning : In the last decades, intensive research has been carried out in order to replace oil-based polymers with bio-based polymers due to growing environmental concerns. So far, most of the barrier materials used in food packaging are petroleum-based materials. LÄS MER
