A novel waterborne polyurethane (WPU) modified by tung oil was prepared with 2,4-tolylene diisocyanate, polyethylene glycol, dimethylol propinic acid, 1,4-butanedilo as main materials via acetone process. The structure of WPU molecule was characterized by FT-IR. Adhesive behavior for non-polar and/or low surface energy soft packing films was studied. Water resistance of films were evaluated by water contact angle and water uptake and thermal properties determined by thermal analysis instruments. The results show that the modified WPU films have good water and heat resistance. Both of modified WPUs or not have good adherence on BOPP films.

Selecting lactam 2,6-pyridinedicarboxamide (PDCA) as the ligand and 1,4-butanediol as chain extender, we prepare polyurea polyurethane PDCA-PU; then, introduction of rare earth ion Eu3+ and small molecule ligands 1,10-phenanthroline (phen), synthesized binary and ternary polyurethane composite containing Eu3+, and comparing the fluorescence properties of the material. We investigated the thermal stability and luminescence properties of hybrids and found that the ternary hybrid materials exhibit better thermal stability and stronger emission intensity.
