摘要

Eco-friendly corn starch polysachride based green foams (SBF) with varying concertations of lignocellulosic water hyacinth plant fiber were fabricated using microwave heating. The prepared foams were compared with Expanded Polystyrene (EPS) against inherent properties. The EPS performed better than SBF regarding density and thermal conductivity, and SBF was more hydrophilic and biodegradable in comparison to EPS (p < 0.05). The SBF with 10% plant fiber showed a lowest density of 0.54 ± 0.02 and a comparable compression force values of 5.8 ± 0.8a as EPS, and all the SBF under investigation had superior electrostatic dissipative properties, which made them better at handling electrostatic discharge. SEM analysis proved that the microstructure and pore size was influenced by plant fiber integration. Maximum degradation (58.2 ± 24.4%) on soil burriel test was reported in the sample with 10% fiber. The TGA and DSC analysis inferred that the plant fiber incorporation in moderate concentrations (5–10%) improved the thermal stability of starch foams. The FTIR spectra of plant fiber-reinforced foams exhibited a new peak at 1745 cm⁻¹, indicating C = O stretching vibration, likely due to the presence of an acetyl group in the bio-foam, confirming the reinforcement of plant fiber, while XRD results indicated the absence of crystallinity in the bio-foam samples. The study concluded that SBF with 10% of plant fiber could be a potential sustainable alternative to EPS in the transit of electrostatic charge-sensitive goods.
