Wear-resistant coatings for solar cell panels

Song K., Arizona State University, US

This research studied the relationship between nano-particle orientation and wear resistance. Nano-particle orientations were tailored through flow-assisted spray technical and parallel, randomly distributed, and preferentially vertical configurations were achieved. Surface damage tests were managed using [...]

Self-healing and self-cleaning nanocomposite coatings

Song K., Arizona State University, US

This work reports on the healing of translucency, roughness, nanoindents, and shallow scratches in polymer/nano-particle composites. Mechanical loading were applied on polymer/self-healing additive/nano-particle composites. The concentration of nano-particles and self-healing additives were optimized to 1.0 [...]

Aligned HNT for Abrasion Resistance in Solar Cell Coatings

Song K., Polak R., Askar K.A., Rubner M.F., Cohen R.E., MIT, US

Halloysite nanotubes (HNT), a kind of naturally formed ceramics, encompass high aspect ratio, stiffness and low cost while remain understudied about their coating usage. Theoretical and experimental results have shown a modulus as high as [...]

Facile Spray Coating in Preparing Anisotropic Composites

Song K., Polak R., Abdalla Askar K., Rubner M.F., Cohen R.E., MIT, US

Anisotropy has been taken advantage in composites to achieve specific mechanical, electrical, magnetic and other functional properties. In composite mechanics, orientation of fiber in polymer matrix will reinforce the composites to the greatest potential along [...]

Inducing Polymer Interphase Formation in the Composite at Low Nano-Carbon Loading

Song K., Minus M.L., Northeastern University, US

The nano-carbons used in this work are layered carbon nano-chips that exhibit platelet morphology and are able to slide with respect to each other. Both filled and unfilled poly(vinyl alcohol) (PVA) fibers were studied to [...]
