As a biological material, bamboo has the advantage of fast growth, low energy consumption during processing and much higher strength compared with other herbaceous plants. Manufactured bamboo is widely used in many fields, such as furniture, buildings, musical instruments, and so on. The bamboo industry supplies earnings, food, and fibre for more than 2.2 billion people half the world’s population is involved in using and trading bamboo products. Based on our findings, we conclude that plasma treatment can alter parameters such as surface energy and roughness that could improve glue bonding of green bamboo, but delays between plasma treatment and further processing would need to be minimized.Īs primary forest area declines, fast growing bamboo is becoming more important as a source of biomaterials especially for forest-deficient countries, such as India, China, and so on. However, this effect was temporary and contact angle increased with time and recovered approximately 30% of its original value after 24 h. Plasma treatment was effective at converting green bamboo surfaces from hydrophobic (initial contact angle >110°) to hydrophilic (contact angle <20°). Plasma was able to etch bamboo green surfaces, and make them rougher and more powdery. Confocal profilometry and SEM revealed that the morphology of green bamboo surfaces varied between 3 different stems. The effects of plasma treatment on green bamboo stems were examined using contact goniometry (wettability), non-contact confocal profilometry and scanning electron microscopy (SEM). This study focused on using glow-discharge plasma to treat green bamboo surfaces to make them less hydrophobic. Hence, the recovery and utilization ratio of bamboo during processing is low. The inner and outer surfaces of bamboo stems are usually removed prior to the manufacture of bamboo panels because the surfaces are hydrophobic and difficult to bond with glue.
