The wetting phenomena and surface energetic behavior in heat-treated bamboo were studied. The bamboo specimens were heat-treated at temperatures of 100, 140, and 180 °C for 4 h, and an untreated sample served as a control. The sessile drop technique was used to estimate the surface contact angles of the control and heat-treated bamboo samples. The contact angle data were then used to determine the surface free energies using the Lifshitz-van der Waals/acid-based approach. The results revealed that the heat treatment process affects surface wettability. Heat treatment at 100 to 180 °C increased the contact angle of distilled water and formamide, but heat treatment did not cause any increase in the contact angle of diiodomethane. The hydrophobic characteristics of the bamboo surfaces also increased under heat treatment, and the surface free energy and the polarity of the bamboo decreased. Surface analysis by XPS of the samples heat-treated at 180 °C showed a decreased O/C ratio and increased C1 peak, indicating that more lignin and extractives were situated on the bamboo surface. Changes in wettability can greatly impact the use of the material, particularly with respect to the adhesion of paints and coatings.

Maximiliano dos Anjos Azambuja 2RESUMO: A presente pesquisa, realizada em Portugal, tem como objetivo a compreensão dos conceitos de sustentabilidade, construções verdes e planejamento sustentável. Foi realizado um levantamento bibliográfico a cerca do tema, durante o estágio no exterior, buscando compreender mais a fundo tais conceitos. Um estudo de caso foi realizado no bairro da freguesia de Santo Antônio da Charneca, visto como projeto de urbanização sustentável, em Portugal. A pesquisa retrata a compreensão dos preceitos básicos de sustentabilidade e comenta o sucesso da implantação no estudo de caso.

“…When the temperature was changed from 180 o C to 200 o C, a reverse trend was found. The reason for the slight decrease is not yet entirely understood, but it could be a result of the following reasons: material degradation at the superheated temperature, as well as a possible coking phenomenon, may lead to embrittlement of the surface (Mahdavi et al 2012;Alireza and Amir 2008). In general, the effect of press temperature on the static bending of CBP (laminated with MDF) was significant.…”

“…1087 2004; Zhang et al 2013;Sumardi et al 2007). Furthermore, its fast growth rate can support intensive and sustainable use in the particleboard industry (Mahdavi et al 2012;Umit et al 2012). Corrugated composite, a kind of laminated plate with sandwich structure, is commonly used because of its ability to withstand higher loads before buckling compared to plain sheets.…”

A simple, practical, and low-technology approach was developed to fabricate corrugated bamboo particleboards (CBP), a novel bamboo product with a corrugated structure, from bamboo waste (planer waste). This product could be manufactured anywhere in the world where the bamboo industry develops. The selected mechanical and physical properties of CBP were prepared with urea formaldehyde resin at three press temperatures and two density levels and were evaluated. The results showed that the performance of CBPs is highly dependent upon the board density. The static bending strength of CBP laminated with MDF initially increases, and then decreases with increasing press temperature. Increasing the magnitude of the press temperature has a slightly positive effect on the thickness swelling and water absorption. Compared with the excellent mechanical strength of CBP (laminated with MDF), the thickness swelling value of this bamboo-based particleboard without any waterproofing treatment was lower than the minimal requirement of the EN standard.
