In our  2013   Chemical Communications  paper we report the fabrication of various shaped High Internal Phase Emulsion hydrogels. Key is the use of dilute waterborne poly( N -isopropylacrylamide) microgel dispersions which are non-covalently crosslinked through 2-ureido-4[1H] pyrimidinone (UPy) quadruple hydrogen bond groups. These microgels were developed in one of our earlier papers published in  2013 &nbsp;in  Polymer Chemistry  (read the paper here:  http://dx.doi.org/10.1039/C2PY20615C ).&nbsp;The colloidal particles position themselves at the oil-water interface hereby serving as Pickering stabilizers. Over time they deform and with the excess amount in the continuous water phase they form a non-covalently UPy-crosslinked hydrogel monolith.&nbsp;The reversible UPy crosslinks allow for the HIPE-hydrogels to be molded into objects which are thermo-responsive in Nature.
