Integration of POSS-PCU is improved by increased surface porosity conferred by surface dusting. Scanning electron microscopy (SEM) images of implanted dusted and non-dusted POSS-PCU scaffolds at 4 and 8 weeks post implantation in cross section. Non-dusted scaffolds consistently demonstrated a capsule-like structure with minimal integration compared to sucrose-dusted POSS-PCU scaffolds, which showed tissue ingrowth into individual pores.
