The composites were fabricated using compression moulding and characterised for their mechanical, thermal, acoustic, and water absorption properties. The results showed that the incorporation of PNS biochar significantly enhanced its tensile strength of 47.36 MPa, flexural strength of 82.88 MPa, impact strength of 28.68 kJ/m<sup>2</sup>, and Shore-D hardness of 82.49, with an optimal concentration of 15 wt. %. The thermal conductivity increased to 0.185 W/m·K, while the water absorption in seawater and distilled water was minimised to 3.8% and 5.7%, respectively. The sound absorption properties were also improved, with a maximum noise reduction coefficient (NRC) of 0.30. However, at high biochar concentrations (> 15 wt. %), it led to particle clustering and void formation, resulting in reduced mechanical and acoustic properties. Scanning electron microscopy (SEM) revealed that these biochar composites had minimal void formation and strong interfacial bonding between the biochar and hemp fibres for the optimal 15 wt. % compositions. This highlights the feasibility of using PNS biochar as a sustainable filler in natural fibre composites, offering a promising alternative to synthetic materials with enhanced properties and reduced environmental impact.</p></div>","PeriodicalId":658,"journal":{"name":"Journal of Polymer Research","volume":"32 4","pages":""},"PeriodicalIF":2.6,"publicationDate":"2025-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143688432","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study investigated the impact of varying GO content on the performance of PA10T/10I/GO composites. Antistatic property tests demonstrated that even a small amount of GO significantly reduced the surface resistance of PA10T/10I, with notable improvements observed at just 1 wt.%, enhancing the antistatic properties of the PA10T/10I matrix. Additionally, Differential Scanning Calorimetry (DSC) analysis revealed that the crystallization properties of PA10T/10I were improved by the incorporation of GO, with minimal changes in the melting points of the PA10T/10I/GO composites. The melting temperatures remained in the range of 289.6 ~ 281.9 ℃as the GO content varied from 0.05 to 1 wt.%. Thermogravimetric Analysis (TGA) and Heat Deflection Temperature (HDT) results showed that the PA10T/10I/GO composites exhibited excellent thermal stability, with PA10T/10I/GO-5 (containing 1 wt.% GO) achieving a higher HDT of 105.9 ℃, surpassing that of the PA10T/10I matrix by approximately 10 ℃. Mechanical testing indicated that the tensile strength of PA10T/10I/GO-5 was approximately 28.20% higher than that of PA10T/10I, while the bending strength increased by about 23.03%.
