Bamboo Preservation Experiments as Encapsulation for Liquid-State PCM

Bamboo has been known for its sustainability and versatility, which presents a promising green alternative material from tropical countries. This paper explores bamboo's potential as an encapsulation material for liquid phase change material (PCM), addressing leakage and fungal growth. The experimental procedures involve treating two different types of bamboo (black and tropical green) to see their capability as an encapsulation for phase change material. In addition, three experiments were applied: waterproofing, varnish, and pre-treatment. Qualitative analysis is conducted over a consecutive fourteen-day period, evaluating all the twenty different samples with different treatments as they hold the liquid PCM. Several pre-treated bamboos show leakage. Consequently, varnishing and waterproofing treatments emerged as crucial in effectively addressing bamboo encapsulation. The findings demonstrate that tropical green bamboo, treated with waterproofing on both sides, exhibited impeccable leakage prevention and successfully removed fungal growth, even when exposed to extended periods of moisture.
