Effects of drying time on the surface morphology evolution of urushiol-formaldehyde diethylenetriamine polymer microporous films
Raw lacquer, a renewable and eco-friendly biopolymer material with excellent physico-mechanical properties, has been principally used to coat objects of high artistic and pleasing beauty for centuries. In previous reports, we studied microporous urushiol-based polymer (UBP) films by the water-assisted assembly method. The effect of drying time on the formation of breath figures with honeycomb patterns in the microporous films of urushiol-formaldehyde diethylenetriamine polymer (UFDP) was investigated in this paper. The pattern structure was studied with optical microscopy (OM) and scanning electron microscopy (SEM). The drying time, which is influenced by the reflux time, plays a decisive role in the morphology, such as pore size and distribution periodicity, of the microporous UFDP films. (C) 2012 Elsevier B.
