A new and eco-friendly mussel-inspired surface modification pathway for bamboo fiber (BF) is presented in this study. The self-assembly polydopamine (PDA) coating can firmly adhere on BF surface, which also serves as a bridge to graft octadecylamine (ODA) for hydrophobic surface preparation. The as-formed PDA/ODA hybrid layer could supply abundant hydrophobic long-chain alkyls groups and generated a marked increase in BF surface roughness and a marked decrease in surface free energy. These changes provided advantages to improve fiber–matrix interfacial adhesion and wettability. Consequently, high performance was achieved by incorporating the hybrid modified BF into the polybutylene succinate (PBS) matrix. The resultant composite exhibited excellent mechanical properties, particularly tensile strength, which markedly increased by 77.2%. Meanwhile, considerable high water resistance with an absorption rate as low as 5.63% was also achieved. The gratifying macro-performance was primarily attributed to the excellent interfacial adhesion attained by hydrogen bonding and physical intertwining between the PDA/ODA coating on the BF and the PBS matrix, which was further determined by fracture morphology observations and dynamic mechanical analysis. Owing to the superior adhesive capacity of PDA, this mussel-inspired surface modification method may result in wide-ranging applications in polymer composites and be adapted to all natural fibers.

This paper studies the emission of CO₂ in the production of panel furniture. It gets data of energy consumption and raw material use of panel furniture manufacturers from 2011 to 2015 by auditing 37 representative panel furniture manufacturers in China and uses computational formula which converts fossil fuel combustion and power consumption into CO₂ emission to analyze such data. Meanwhile, it analyzes the sensitivity of various types of energy on CO₂ emission and establishes a mathematical model of carbon emission evaluation. The result shows that carbon emission produced by unit volume of raw materials consumed by panel furniture manufacturers in China is mainly distributed in 3 ladder grades. According to three sections of carbon emission grades formed through the assessment according to calculation results, the upper limits are 0.117 t/m³, 0.252 t/m³ and 0.446 t/m³, respectively. Besides electric energy, sequence of sensitivity of fossil fuel involved in the production is diesel, gasoline and coal from high to low.
