Provided herein are methods for the controlled, independent modification of the surface of polymer-based materials and compositions generated thereby. The methods include use of low temperature plasma for surface modification. The methods allow for the alteration of multiple surface characteristics including generation of precise nanostructures, morphology, crystallography and chemical composition for increased biocompatibility, for example, hydrophilicity, steric hindrance, anti-inflammatory properties and/or anti-bacterial properties.

Described herein are polyester polymer compositions including a polyester polymer, a white pigment and hydroxyapatite. It was surprisingly discovered that polyester polymer compositions including hydroxyapatite maintain outstanding retention of reflective after prolonged exposure to heat and light, while having significantly reduced microblistering and increased mechanical performance relative to analogous polyester polymer compositions including a non-calcium phosphate salt. Accordingly, in some embodiments, the polymer compositions can be desirably incorporated into light emitting diode (“LED”) components.

Described herein are aliphatic polyamide compositions including an aliphatic polyamide, glass fiber and, optionally, one or more additives. It was surprisingly found that aliphatic polyamide compositions containing specifically selected glass fibers had similar dielectric performance, and significantly improved mechanical performance, relative to corresponding aliphatic polyamide compositions containing low dielectric glass fiber. At least partially due to the high dielectric performance (low dielectric constant) and significantly improved mechanical performance, the aliphatic polyamide compositions can be advantageously incorporated into mobile electronic device components.
