We are developing spherical foam shells with density ≤50mg/cm3. Two different approaches to the manufacture of these shells are being pursued: microencapsulation and additive manufacturing via two photon polymerization (2PP). We report on our progress towards making the low-density foam shells by these two approaches.
Initial work to prepare dicyclopentadiene (DCPD) foam for micro-encapsulation will be discussed. Methods for deterministic symmetry control in micro-encapsulated capsules/foam shells will also be outlined.
