“…The intensity ratio of the D and G bands (I D /I G ) of the CNTs increased from 1.56 to 1.71 on acid treatment, as a result of the formation of sp 3 -hybridized carbon defect sites that result from the creation of functional groups. Similar results were observed by Hsu [89] and Hadjiev et al [101] using multi-walled CNTs (MWCNTs). The results of Raman spectroscopy indicated that the I D /I G of O-MWCNTs (1.543) was higher than that of P-MWCNTs (1.244), which was the result of some of the sp 2 carbon atoms being converted to sp 3 carbon atoms on the surface of the MWCNTs as carboxyl groups were formed by the acid treatment [102].…”

“…Unlike other additive such as rubber particles, the presence of liquid crystalline domains will not sacrifice T g or modulus of the material. These outstanding properties make LCE as good candidates for a wide range of potential applications, such as optical switches, electronic packaging, and matrices for high performance composites [21][22][23].…”

Abstract. Graphene oxide (GO) sheets were chemically grafted with thermotropic liquid crystalline epoxy (TLCP). Then we fabricated composites using TLCP-g-GO as reinforcing filler. The mechanical properties and thermal properties of composites were systematically investigated. It is found that the thermal and mechanical properties of the composites are enhanced effectively by the addition of fillers. For instance, the composites containing 1.0 wt% of TLCP-g-GO present impact strength of 51.43 kJ/m 2 , the tensile strength of composites increase from 55.43 to 80.85 MPa, the flexural modulus of the composites increase by more than 48%. Furthermore, the incorporation of fillers is effective to improve the glass transition temperature and thermal stability of the composites. Therefore, the presence of the TLCP-g-GO in the epoxy matrix could make epoxy not only stronger but also tougher.

“…Since CNTs are resilient materials, homogeneously dispersed CNTs can add rigidity and hardness via interfacial interaction with the epoxy matrix. Thus, the soft polymer matrix holds together when challenged by an applied force and the mechanical properties like modulus, hardness are improved [19]. Fourth is the formation of long range ordered structure which can be accomplished by the functionalization of MWNTs.…”

Thermal properties of epoxy composites filled with boric acid P M Visakh, O B Nazarenko, Yu A Amelkovich et al. -Microstructural analysis using X-ray computed tomography (CT) Abstract. Present typescript encompasses anextraordinary electrical and mechanical behaviors of carboxylic (-COOH) functionalized multiwall carbon nanotube (MWNTs)/epoxy composites at low wt.% (0.5, 0.75, 1wt.%). Functionalization on the surface of the nanotube assists MWNTs in dispersing it into epoxy polymer in a respectable manner. Fabricated composites are exposed to different characterization techniques in order to examine the overall physical properties. Microwave shielding effectiveness (SE) for X band (8-12 GHz) and the flexural properties have been premeditated to predict the electrical and mechanical performances.It was found that the total SE of the nanocomposites was increased with the positive gradient of MWNT contents. The best result was recorded for 1 wt.% MWNT loading (SE of about 51.72 dB).In addition, incorporation of nanofillers enhanced the flexural modulus, flexural strength and micro-hardness of the resulting composites while comparing with neat epoxy. Nanocomposites with 0.75 wt.% MWNT loading demonstrated an incrementof 101% in modulus than that of neat epoxy. Theincrement in mechanical properties was due to achievement of good dispersion quality, effective bonding between MWNTs and epoxy polymer analyzed by micrographs of fracture surfaces.
