Formaldehyde emission in wood based panels: Effect of curing reactions

The influence of hexamine formed as byproduct during the UF cure was ignored in the past. However, with the increasing interest on low formaldehyde emission boards, this issue has become more pertinent. Formaldehyde release from hexamine degradation is extensive and could limit the success of the development of low formaldehyde emission adhesives if the conventional latent catalysts remain in use. In this study, formaldehyde released from recycled wood, hexamine and cured UF resin was assesse...

Simple hydrothermal synthesis method for tailoring the physicochemical properties of ZnO: Morphology, surface area and polarity

A simple urea-assisted hydrothermal synthesis method was used to tailor the physicochemical properties ofZnO materials. The role of Pluronic P123 block copolymer in the crystal growth, morphology and specificsurface area of the as-prepared ZnO was studied. When Pluronic P123 is used, well-dispersed hierarchicalmicrospheres, with a flower-like morphology, are obtained, but in its absence large spherical agglomeratedclusters are formed. The polarity of the ZnO, measured as the ratio between pla...

Development of porous polymer pressure sensors incorporating graphene platelets

Electrically conductive polymer composites (ECPCs) based on porous polymeric matrices ofPEBA 4033 incorporating different types of graphene platelets were prepared and tested.PEBA 4033 polymer was mixed with different graphene platelets: grade H5, grade MX andgrade Ce750. Porous morphology was obtained for the ECPCs prepared with grapheneplatelets grade MX and H5, while for the grade Ce750 only a dense ECPCs was obtained.The porous ECPC loaded with 15 vol.% of graphene M5 exhibited a linear p...
