This study focuses on optimizing the physical and mechanical properties of foam materials produced with the addition of sodium alginate as the matrix, and cellulose and activated carbon as fillers. Foam materials, valued for their lightweight and insulation properties, are typically produced from synthetic polymers that pose environmental risks. To mitigate these concerns, this study investigates the potential of natural, biodegradable polymers. Various foam formulations were tested to evaluate their density, compression modulus, and thermal conductivity. The results indicated that an increase in activated carbon content enhanced thermal stability, as indicated by higher Ti% and Tmax% values. Additionally, a higher concentration of sodium alginate and activated carbon resulted in higher foam density and compressive modulus, while cellulose exhibited a more intricate role in the material's behavior. In the optimal formula, where the sum of the component percentages totals 7.6%, the percentages (e.g., 0.5% sodium alginate, 5% cellulose, and 2.1% activated carbon) are calculated based on the weight/volume (/) ratio of each component in the water used to prepare the foam mixture. These results indicate that natural and biodegradable polymers can be used to develop high-performance, eco-friendly foam materials.
本研究着重于优化以海藻酸钠为基质、纤维素和活性炭为填料制备的泡沫材料的物理和力学性能。泡沫材料因其轻质和隔热性能而受到重视，通常由具有环境风险的合成聚合物制成。为减轻这些担忧，本研究调查了天然可生物降解聚合物的潜力。测试了各种泡沫配方以评估其密度、压缩模量和热导率。结果表明，活性炭含量的增加提高了热稳定性，较高的Ti%和Tmax%值表明了这一点。此外，较高浓度的海藻酸钠和活性炭导致泡沫密度和压缩模量更高，而纤维素在材料性能方面表现出更为复杂的作用。在最佳配方中，各组分百分比总和为7.6%，这些百分比（例如，0.5%海藻酸钠、5%纤维素和2.1%活性炭）是根据用于制备泡沫混合物的水中各组分的重量/体积（/）比计算得出的。这些结果表明，天然可生物降解聚合物可用于开发高性能、环保的泡沫材料。
