Synthesis Of Double Network Hydrogels Which Can Be Shaped Freely, Natsuki Morimoto, Norie Kato
The International Student Science Fair 2018
Double network (DN) hydrogels have specific characters such as flexibility and high mechanical strength. They are expected to use biomaterials such as artificial cartilages and meniscuses. The purpose of this study is to synthesize DN gels which can be shaped freely. DN gels were synthesized by polyvinyl alcohol (PVA) as a mold, 2-acrylamide-2-methylpropane sulfonic acid (AMPS) as a first monomer, N,N’-methylene-bis-acrylamide (MBAA) as a crosslinker, 2-oxoglutalic acid (OGA) as an initiator and acrylamide (AAm) as a second monomer. First, PVA (polymerization degree; 2000) was dissolved in the water and prepared to 15 % of aqueous solution. It was poured in …

An Entirely New Molecular Glue For Mof Using Unusual Structural Transformation Of A Coordination Polymer, Sukwoo Jung, Hangyeol Kim, Junseok Ahn
The International Student Science Fair 2018
In this research, an entirely new molecular glue is reported. This ‘coordination polymer glue’ is synthesized from zinc metal and BDC-NPE(2,5-bis{4-[1-(4-nitrophenyl)ethylamino]butoxy}terephthalic acid). Molecular glue transforms from 1D coordination polymer to a 3D cross-linked framework, resulting in a phase change of solution to solid. The carboxylate group of this glue makes the preformed MOF bind to its framework. Therefore, when the solution of molecular glue is mixed with preformed MOF powder and heated, homogeneous and thin MOF film – MOF/ZnNPE film – is fabricated. The film is irrelevant to the kind of its substrate, and its thermal stability was enhanced in …
