Abstract: An apparatus, method, and system for post-processing a printed graphene ink pattern or other deposition on a substrate. A pulsed UV laser is tunable between various energy densities to selectively modify the printed ink or deposition in electrical or physical properties. In one example, radical improvements in electrical conductivity are achieved. In another example, controlled transformation from essentially 2D printed or deposited graphene to surface topology of 3D nanostructures are achieved. The 3D structures are beneficial in such applications as electrochemical sensors of different types and characteristics. In another example, hydrophobicity of the printed or deposited graphene can be manipulated starting from a hydrophilic to super hydrophobic surface.

Abstract: This patent document provides a caged catalyst comprising a catalyst encapsulated in a cage compound of Formula I represented [ZrIV6O4(OI)4(linker)6]). The catalysts demonstrated excellent activities and size selectivity in a model RCM reaction, suggesting successful encapsulation into MOFs. ROMP of cyclopentene mediated by G3@UiO-67 achieved significantly higher molecular weight and lower dispersity than the counterpart mediated by the free catalyst. The ultra-high molecular weight polymers generated by the encapsulated catalysts demonstrated significantly improved mechanical and adhesive properties compared to the low molecular weight counterparts and commercial polymers. The simplicity and generality make this method readily applicable to the ROMP of a wide range of low-strain cyclic olefins.

Abstract: One aspect of the present application relates to a method of synthesizing a thermoplastic polymer. This method includes providing a depolymerized lignin product comprising monomers and oligomers and producing lignin (meth)acrylate monomers and oligomers from the depolymerized lignin product. A thermoplastic lignin (meth)acrylate polymer is then formed by free radical polymerization of the lignin (meth)acrylate monomers and oligomers. The present application also relates to a branched chain thermoplastic lignin (meth)acrylate polymer which includes a chain transfer agent. The thermoplastic lignin based polymers of the present application can be used to prepare carbon fibers, and engineering thermoplastics. Mixtures of lignin (meth)acrylate monomers and oligomers are also disclosed.
