Boron nitride nanosheets (BNNSs) are two dimensional crystals composed of boron and nitrogen atoms covalently bonded in a hexagonal manner with exceptional physiochemical properties. However, the researches on BNNS rather limited due to lack an efficient method prepare BNNS. In this study, we report facile for fabrication through liquid-phase exfoliation particles (h-BNs) methanesulfonic acid. The resultant can be readily disperse number organic solvents, such as N-methyl-2-pyrrolidone....

Three-dimensional (3D) structures of graphene have attracted extensive interest for their practical applications, such as supercapacitors and catalyst supports. Self-assembly is a typical technique to fabricate macroscopic materials integrated with various superior properties. However, an efficient environmentally-friendly strategy still needed.

Aramid macroscale fibers, also called Kevlar exhibit extremely high mechanical performance. Previous studies have demonstrated that bulk aramid fibers can be effectively split into nanofibers (ANFs) by dissolution in dimethylsulfoxide (DMSO) the presence of potassium hydroxide (KOH). In this paper, we first introduced ANFs structure graphene nanosheets through non-covalent functionalization π-π stacking interactions. nanofiber-functionalized sheets (ANFGS) were successfully obtained adding...

Multiwalled carbon nanotubes (MWNTs) have been widely used as mechanical reinforcement agents in the past few years. However, enhancement of properties composites has greatly hampered by its limited available interface area composites. Toward solving this intrinsic limitation MWNTs, paper, we report use unzipped MWNTs (uCNTs) nanofillers for polymer first time. The uCNTs were produced an oxidative unzipping process, involving lengthwise cutting and opening walls yielded separated ribbonlike...

The emerging field of graphene(GP)-based polymer nanocomposites has continued to be the focus considerable interest in recent years because unparalleled improvement shown mechanical, thermal, and electrical properties compared neat polymer. However, these improvements largely depend on synthesis well-exfoliated high-quality GP. In this paper, we report a facile method for production GP sheets through liquid-phase exfoliation graphite methanesulfonic acid (MSA). Raman, X-ray photoelectron...

Abstract This study investigates how different fiber types enhance the mechanical properties of simulated lunar soil-based polymers. Basalt fiber, polyvinyl alcohol and polypropylene were selected as reinforcing materials for experimental analysis flexural toughness. The results indicate that significantly improves polymer, achieving maximum performance at a doping rate 0.4 wt%. compressive strength, mid-span deflection increase by 54.5%, 117.7%, 90%, respectively, compared to baseline group...

Multiwalled carbon nanotubes (MWNTs) have been widely used as nanofillers for polymer reinforcement. However, it has restricted by the limited available interface area of MWNTs in matrices. Oxidation unzipping is an effective way to solve this problem. The unzipped multiwalled nanotube oxides (UMCNOs) exhibit excellent enhancement effect with low weight fractions, but agglomeration UMCNOs at a relatively higher loading still hampered mechanical reinforcement composites. In paper, we...

Multiwalled carbon nanotubes (MWNTs) have been widely used as mechanical reinforcement agents during the past decades. However, complete achievement of enhancement has greatly impeded by their limited available interfacial area (AIA) and weak adhesion force with polymer matrix. In this paper, we use unzipped MWNTs (uCNTs) a precursor to fabricate poly(methyl methacrylate) (PMMA) functionalized uCNTs (uCNTs-P) via in situ free radical polymerization. Fourier transform infrared (FTIR), X-ray...
