In this study, the synthesis and characterization of functionalized flax fabric with adequate titanium and aluminium precursors is presented (AlCl₃ or Ti(C₄H₉O)₄). The modified flax fabrics were analysed both visually and instrumentally by IR spectroscopy and microscopy, scanning electron microscopy (SEM) and thermal analysis (DTA-TG). The data highlight that the nature and amount of functionalizing agent induce important morphological changes of the surface. These flax fabrics decorated with alumina or titanium dioxide nanoparticles are desired to be used as reinforcing agents of different recycled polyethylene terephthalate. The properties will be designed by the nature, processing route and amount of the precursors used for the surface modification of these cellulosic fibres/fabrics, the surface decoration increasing their thermal properties (especially thermal stability) but also surface properties (especially roughness, hydrophilic/hydrophobic ratio, etc.). All these factors will finally induce improved compatibility between phases and thus improved physico-mechanical and thermal properties. Taking into account the large amount of natural cellulosic fibres and recycled thermoplastic polymers, added-value products will be obtained and at the same time some environmental issues are solved. The expected applications can include the fabrication of automotive parts, protective panels for highways and railways, etc.

纳米颗粒亚麻纤维织物表面装饰-开发热塑性聚合物杂化增强剂的有前途的工具

在这项研究中，提出了具有适当的钛和铝前体（AlCl ₃或Ti（C ₄ H ₉ O）₄）。改性的亚麻织物通过红外光谱和显微镜，扫描电子显微镜（SEM）和热分析（DTA-TG）在视觉上和仪器上进行了分析。数据表明，功能化剂的性质和数量会引起表面的重要形态变化。这些用氧化铝或二氧化钛纳米颗粒装饰的亚麻织物期望用作不同的再循环聚对苯二甲酸乙二醇酯的增强剂。这些性质将由用于这些纤维素纤维/织物表面改性的前体的性质，加工途径和数量来设计，表面装饰可提高其热性能（尤其是热稳定性），但也可以提高表面性能（特别是粗糙度，亲水性/疏水比例等）。所有这些因素最终将导致相间相容性的改善，从而改善物理力学和热学性质。考虑到大量的天然纤维素纤维和回收的热塑性聚合物，将获得增值产品，同时解决一些环境问题。预期的应用将包括汽车零件的制造，公路和铁路的防护板等。
