Abstract
Sheath bamboo leaves (SBL) are potential lignocelluloses waste, aimed to produce laminated architectonic coatings. In this work was studied the surface interaction among the SBL and three types of adhesive: Polyvinyl Acetate (PVAc), Castor oil Polyurethane Adhesive bi-component (Vegetal PU), Polyester Resin unsaturated bi-component (Polyester R.); through energy surface, by measuring water absorption capacity, contact angle and digital optical microscopy. The results showed that PU vegetal decrease the water absorption capacity showing a good adhesion at SBL surfaces, in comparison with PVAc and Epoxy resin. Contact angle tests showed that castor oil based PU Resin and Epoxy resin adhesive scattering well in the surface in comparison with water based adhesive like PVAc. Apparently, in the visual and aesthetic analysis by digital optical microscopy, PVAc let see the real SBL appearance, due to low reflectance.We shall be able to publish your paper in electronic form on our web page http://www.scientific.net, if the paper format and the margins are correct.Your manuscript will be reduced by approximately 20% by the publisher. Please keep this in mind when designing your figures and tables etc.
