Surface modification to enhance photo-stability of polymers

نویسندگان

چکیده

Photo-degradation is an irreversible alteration in the chemical, mechanical and physical properties of polymers, these alterations are a result photon absorption from sunlight. UV-light considered to be main factor for initiating photo-degradation process polymers. To extend lifetime their durability, overall minimization rate photo degradation protection polymers against environmental factors, stabilizers introduced In addition, since interaction polymer with its environment occurs mainly at surface polymer, therefore modification used enhance UV photo-stabilization. This method can also provide more durable, weather resistant photo-stable

Novel nanomicelle formulation to enhance bioavailability and stability of curcuminoids

Objective(s): Curcuminoids, comprising curcumin, demethoxycurcumin (DMC) and bisdemethoxycurcumin (BDMC), are bioactive phytochemicals with numerous pharmacological effects. Oral biological availability of curcuminoids is low due to the low aqueous solubility and rapid metabolism. This study aimed at fabricating a nanomicellar curcuminoid formula with enhanced pharmacokinetic properties. Materi...

A short review on Ferrofluids surface modification by natural and biocompatible polymers

This paper provides an overview of how the surface properties of ferromagnetic nanoparticles dispersed in fluids is modified by natural and biocompatible polymers. Among common magnetic nanoparticles, magnetite (Fe3O4) and maghemite (g-Fe203) are popular candidates because of their biocompatibility. Natural polymeric coating materials are the most commonly used biocompatible magnetic nanopartic...

Surface modification of mammalian cells with stimuli-responsive polymers.

In order to introduce alternative functions into mammalian cells and control them under ambient conditions, poly(N-isopropyl acrylamide) (PNIPAM) was immobilized on the cell surface. Cellular aggregation could be regulated by temperature change. In addition, separation of PNIPAM-conjugated glycoproteins was successfully performed.

Surface modification of polymers using a multi-step plasma treatment

We report a simple method for fabrication of one-dimensional, two-dimensional and nested hierarchical wrinkling patterns on polymeric surfaces using plasma treatment. The morphology of wrinkle patterns, specifically the wavelength and amplitude of each wrinkle generation, is controlled by the treatment time and stretching release after each treatment step. By systematically varying these two ke...
