摘要

天然防霉剂因其可再生、环保等特点,被广泛应用于木质建筑材料中。本研究创新性地提出了一种木质细胞腔来封装植物精油填充人造板,以提高其疏水性和抗真菌性能。利用木材细胞壁强大的天然屏障功能,构建亲酯木精油微胶囊(EO-EWM),将杉木精油包封在细胞腔内。精油在EO-EWM中的载药量达到695.3 mg/g,缓释性能优异,模拟释放56 d后,精油的释放率为59.9 %。释放机制遵循浓度梯度驱动的菲克扩散机制。在人造板的压制过程中,EO-EWM的添加量控制在30 %以内,以保证人造板的力学性能。更重要的是,EO-EWM的加入显著提高了人造板的自洁能力和疏水性,同时有效降低了人造板霉菌生长的风险。精油人造板(EO-WBP)对黑曲霉的抑菌率为75.0% %,对柑橘青霉的抑菌率为83.3% %。杉木精油抑霉的主要机理是使菌丝体变形、收缩、开裂,从而抑制或杀死霉菌。本研究为构建具有疏水性和抗真菌性能的建筑材料人造板提供了一种有效的环保策略。

Microcapsules loaded with essential oil: Enhancing the hydrophobic and antifungal properties of wood-based panels
Natural anti-mildew agents are widely used in wood building materials because of its renewable and environmental protection characteristics. This study innovatively proposed a wood cell cavity to encapsulate plant essential oil for filling wood-based panels, aiming to enhance hydrophobicity and antifungal performance. Essential oil-esterophilic wood microcapsules (EO-EWM) were constructed with the strong natural barrier function of the wood cell walls to encapsulate fir essential oil in the cell cavity. The loading capacity of the essential oil in EO-EWM reached 695.3 mg/g, exhibiting outstanding slow-release properties, with a release rate of 59.9 % after 56 days of simulated release. The release mechanism followed the Fickian diffusion mechanism driven by concentration gradients. During the pressing process of the wood-based panel, the additional amount of EO-EWM was controlled within 30 % to ensure the mechanical properties of the panels. More importantly, the addition of EO-EWM significantly enhanced the self-cleaning capability and hydrophobic performance of the wood-based panels while the risk of mold growth on the panels reduced effectively. Essential oil wood-based panels (EO-WBP) exhibited effective antifungal of 75.0 % against Aspergillus niger and of 83.3 % against Penicillium citrinum. The main mechanism of the anti-mold was that the fir essential oil caused the distortion, shrinkage, and cracking of mycelium, thus inhibiting or killing mold. This study provides an effictive and environmentally friendly strategy for constructing hydrophobic and antifungal properties of wood-based panel for building materials.

期刊介绍: Industrial Crops and Products is an International Journal publishing academic and industrial research on industrial (defined as non-food/non-feed) crops and products. Papers concern both crop-oriented and bio-based materials from crops-oriented research, and should be of interest to an international audience, hypothesis driven, and where comparisons are made statistics performed.
