The potential for a facile aqueous-based solvent processing route for the synthesis of all-cellulose composites (ACCs) is explored using aqueous solutions containing tertabutylphosphonium hydroxide (TBPH). Specifically, ACC laminates are prepared via the partial dissolution of a woven textile of cellulose II using aqueous TBPH solutions. The dissolved cellulose was then regenerated to reform a cellulose II matrix phase in situ that acts to bond the original undissolved fibres. The hygroscopic behaviour and dissolution analysis of the solvent system showed wide range in the choice of processing conditions suited to the production of ACC laminates via TBPH. The effect of solvent concentration on the microstructure, crystallinity and tensile properties of ACCs is reported. The use of TBPH enables reductions in the processing cycle time and improved control over the properties of ACCs, indicative of a promising solvent system for the upscaled production of ACCs and their laminates.

使用包含氢氧化叔丁基phosph（TBPH）的水溶液探索了用于合成全纤维素复合材料（ACC）的简便的水基溶剂处理路线的潜力。具体地，通过使用TBPH水溶液将纤维素II的织造织物部分溶解来制备ACC层压材料。然后使溶解的纤维素再生以原位重整纤维素II基质相，该相起粘合原始的未溶解纤维的作用。溶剂体系的吸湿性和溶解性分析显示，在适合通过TBPH生产ACC层压板的加工条件选择范围很广。报道了溶剂浓度对ACC的微观结构，结晶度和拉伸性能的影响。
