Abstract

original image

Non-planar non-cracking honeycomb (HC) structures are prepared from star polymers with high glass transition temperatures (Tg) and relatively low Young's moduli (E). This study demonstrates that the Young's modulus of a polymer is a more important factor than the glass transition temperature for determining the occurrence of cracking during HC film formation on non-planar surfaces.
