Smart Magnetic Composites

Nanoparticle-Liquid Crystalline Elastomer Composites

Liquid crystalline elastomers (LCEs) exhibit a number of remarkable physical effects, including a uniquely high-stroke reversible mechanical actuation triggered by external stimuli. Fundamentally, all such stimuli affect the degree of liquid crystalline order in the polymer chains cross-linked into an elastic network. Heat and the resulting thermal actuation act by promoting entropic disorder, ...

Plasmonic Nanoparticles-Liquid Crystal Composites†

We report on the plasmonic properties of 6 nm gold nanoparticles that form highly stable solutions in the nematic liquid crystal 4-cyano-4-n-pentylbiphenyl (5CB). The nanoparticles were covalently functionalized with 4-sulfanylphenyl-4-[4-(octyloxy)phenyl]benzoate, which resembles the structure of the 5CB molecules. The solubility of these nanoparticles in 5CB was significantly higher than that...

Corrosion Sensing Smart Polymeric Coatings

Smart materials cover a wide and developing range in engineering & medical application. This paper presents the “Stimuli-sensitive/smart” polymeric systems which can overcome dramatic property changes responding to small changes in its surrounding environment. Here there is a corrosion resistant or protective smart polymeric coating and paints have been described. Additional smart-coating princ...
