摘要
以甘蔗渣为原料,利用豆豉霉(根霉寡孢霉)制备生物泡沫杯。添加大豆粉促进菌丝体生长,菌丝体与甘蔗渣纤维基质结合。主要原料为全甘蔗渣(B)和深度甘蔗渣(DB)。SF与甘蔗渣的质量比分别为1:1 (SF1)和1.5:1 (SF1.5)。因此,所研究的标本被标记为B-SF1、DB-SF1、B-SF1.5和DB-SF1.5。分析了所有生物泡沫杯的物理性能(吸水率和孔隙率)、机械性能(穿刺和抗压强度)、生物降解性和热性能(热重分析)。B型生物泡沫杯吸水率最低(23%±2.45%),SF1.5型生物泡沫杯吸水率最低(25.83%±5.19%)。B-SF1和B-SF1.5的孔隙率均低于DB生物泡沫杯(分别为8.72%±0.88%和10.77%±1.54%)。此外,与DB样品相比,B生物泡沫杯具有更光滑的生物泡沫表面,更小的空隙和更低的孔隙率。然而,DB生物泡沫杯在所有样品中表现出最高的穿刺强度(2.95±0.37 kg cm−2)。然而,B-SF1.5生物泡沫杯在14天后的抗压强度最高(3.98±0.39 MPa),而DB-SF1.5的降解率最低(27%±0.7%)。B-SF1.5的热稳定性最高,热降解温度为264℃。总体而言,B-SF1.5表面光滑,热稳定性好,抗压强度高。
Characteristics of Biofoam Cups Made from Sugarcane Bagasse with Rhizopus oligosporus as Binding Agent
This study is aimed at producing a biofoam cup made from sugarcane bagasse with tempeh mold (Rhizopus oligosporus). Soybean flour (SF) was added to promote the growth of mycelia, which could bind the bagasse fiber matrix. The main materials were whole bagasse (B) and depithed bagasse (DB). The SF weight ratios to bagasse were 1 : 1 (SF1) and 1.5 : 1 (SF1.5). Therefore, the studied specimens were labeled B-SF1, DB-SF1, B-SF1.5, and DB-SF1.5. All biofoam cups were analyzed for their physical properties (water absorption and porosity), mechanical properties (puncture and compressive strengths), biodegradability, and thermal properties (thermogravimetric analysis). The lowest water absorption rates were obtained from the B biofoam cups (
