Poly(lactic acid) stereocomplex microspheres as thermally tolerant optical resonators

Abstract

Thermally tolerant polymer optical resonators are fabricated from a stereocomplex of poly(l-lactic acid) and poly(d-lactic acid) through the oil-in-water miniemulsion method.

Functional oligo- and polypeptide assemblies for photochemical, optical and electronic applications

“…Recently, Suharman et al reported thermally tolerant microsphere resonators from quasi-natural poly(lactic acid). 63 Upon mixing poly( l -lactic acid) and poly( d -lactic acid), polymers form a stereocomplex, which enhances thermal stability. As a result, optical resonator properties are preserved even at 230 °C, which is 70 °C higher than the acceptable temperature for homochiral microspheres of poly( l -lactic acid) or poly( d -lactic acid).…”
