Residual hemp (Cannabis sativa) hurd fibers obtained from hydrothermal, carbonate, and kraft treatments were the resources used to obtain lignocellulosic nanofibers (LCNF) by using an ultra-fine friction grinder. The morphological, crystallinity, and chemical characteristics of the nanocellulose films were carried out using SEM, XRD, EDX and ToF-SIMS. Water barrier properties of the same were measured in terms of water contact angle, water vapor permeability (WVP) and water absorption. The barrier properties were found to be dependent not only on the lignin content and lignin distribution, but also on the film density and porous structure. LCNF films and coatings showed much higher water contact angle (WCA) (80°-102°) than films produced from the bleached CNF. WVP was found to be more dependent on the density of films than lignin content. Overall, LCNF-based films and coatings derived from hemp hurd residual fibers can contribute to a circular economy and sustainability.

残留大麻（大麻从水热处理，碳酸盐处理和牛皮纸处理获得的夹心纤维是通过使用超细摩擦研磨机获得木质纤维素纳米纤维（LCNF）的资源。使用SEM，XRD，EDX和ToF-SIMS进行了纳米纤维素膜的形貌，结晶度和化学特性的研究。通过水接触角，水蒸气渗透率（WVP）和吸水率来测量相同的阻水性能。发现阻隔性能不仅取决于木质素含量和木质素分布，而且还取决于膜的密度和多孔结构。LCNF薄膜和涂层的水接触角（WCA）（80°-102°）比用漂白CNF生产的薄膜要高得多。发现WVP比木质素含量更依赖于薄膜的密度。全面的，
