Functional fabrics have gained attention as an environmentally-friendly synthesis route. In the current study, novelty bamboo pulp fabrics with thermal conductivity properties were prepared by coating the fabric with graphene and cellulose nanocrystal (G/CNC) solutions. The influences of G and CNC concentrations on properties of fabrics were studied. The viscosities of the G/CNC solutions increased with an increase of G contents. G had an obvious thickening effect. Furthermore, compounded fabrics with different G and CNC contents (GCBPFs) were prepared and extensively characterized in terms of thermal and mechanical properties, and morphology. The ultimate thermal conductivity, bursting strength, and tensile strength of the GCBPF were 0.136 W/m·K, 1.514 MPa, and 25.8 MPa, with 4 wt.% CNC and 3 wt.% G contents, respectively. The results demonstrated that the as-fabricated GCBPFs with favorable thermal conductivity could be applied as a novel fast cooling textile for the clothing industry.
功能性织物作为一种环保的合成途径受到了关注。在当前的研究中，通过用石墨烯和纤维素纳米晶体（G/CNC）溶液对织物进行涂层处理，制备出了具有导热性能的新型竹浆织物。研究了G和CNC浓度对织物性能的影响。G/CNC溶液的粘度随着G含量的增加而增加。G具有明显的增稠效果。此外，制备了具有不同G和CNC含量的复合织物（GCBPFs），并对其热性能、力学性能和形态进行了广泛表征。当CNC含量为4 wt.%、G含量为3 wt.%时，GCBPF的极限热导率、 bursting强度和拉伸强度分别为0.136 W/m·K、1.514 MPa和25.8 MPa。结果表明，所制备的具有良好导热性的GCBPFs可作为一种新型的快速冷却纺织品应用于服装行业。
