| 中文摘要: |
| 本研究以二甲基亚砜（DMSO）/H2O/KOH为溶剂，对芳纶纳米纤维（ANF）/氮化硼纳米片（BNNS）复合纸进行溶解，研究不同BNNS质量分数的ANF/BNNS复合纸的溶解速率差别，探究ANF/BNNS复合纸的微溶解规律。结果表明，纯ANF纸的拉伸强度为48.8 MPa，从25 ℃升高至70 ℃所需时间为6 s，溶解厚度为42.0 μm，而ANF/BNNS复合纸（BNNS质量分数20%）的拉伸强度降低至34.5 MPa，从25 ℃升高至70 ℃仅需2 s，溶解时间为3 h，溶解厚度为52.5 μm，较纯ANF纸的溶解厚度提升了25%，表明BNNS的加入会略微降低ANF/BNNS复合纸的机械强度，显著提升ANF/BNNS复合纸的导热性能，并促进ANF/BNNS复合纸的溶解。 |
| Abstract: |
| In this study， DMSO/H2O/KOH was used as the solvent to dissolve aramid nanofiber (ANF)/boron nitride nanosheet (BNNS) composite paper， to study the difference in the dissolution rate of ANF/BNNS composite paper with different BNNS contents， and to investigate the micro-dissolution law of ANF/BNNS composite paper. The results showed that the tensile strength of pure ANF paper was 48.8 MPa， the time required to increase from 25 ℃ to 70 ℃ was 6 s， and the dissolution thickness was 42.0 μm， while the tensile strength of ANF/BNNS composite paper with BNNS content of 20% was reduced to 34.5 MPa， and the time required to increase from 25 ℃ to 70 ℃ was only 2 s. The dissolution time was 3 h， and the dissolution thickness was 52.5 μm， which was 25% more than that of pure ANF paper. It was indicated that the addition of BNNS slightly reduced the mechanical strength of the ANF/BNNS composite paper， significantly improved the thermal conductivity of the ANF/BNNS composite paper， promoted the dissolution of the ANF/BNNS composite paper. |
