In this study, a TiO2/polyurethane composite (PU-TiO2) for photodegradation of formaldehyde was prepared based on TiO2 amino-functionalized with 3-aminopropyltriethoxysilane (APTS). FTIR, XPS, TG and TEM measurements demonstrated the successful amino-functionalization by APTS. Then NH2-TiO2 were incorporated into polyurethane (PU) through urea linkages, thermal stability, mechanical properties ...

When applying an adhesive to wood, the chemical heterogeneity of wood cell walls makes it difficult understand contribution they make interfacial adhesion between and as is a very complex physical phenomenon. This study, for first time, directly measured surface cellulose, major component urea–formaldehyde (UF) resin adhesives. The thin, smooth nanocellulose films, such cellulose nanofibrils (C...
