Interfacial modification of boron nitride nanoplatelets for epoxy composites with improved thermal properties

Enhanced thermal and mechanical properties of epoxy composites by mixing thermotropic liquid crystalline epoxy grafted graphene oxide

“…First, nanosheets confine polymer chains and reduce the chains mobility after introducing nanosheets into the matrix. It is believed that nanosheets can act as physical interlock points in the cured organic matrix, which generally not only provides a sterically hindered environment for curing reactions of composites, but also restrains the chain mobility [37]. Second, the matrix and chemical groups on the filler surface may participate in the curing reaction, leading to the higher crosslinking density.…”

The Effect of Adding Carbon Nitride Nanometer Material on The Properties of Epoxy Resin Project

“…With the development of epoxy composite material with both high thermal conductivity and excellent mechanical properties in various areas of weight-sensitive aerospace industry, marine, armor, automobile, railway and sporting goods industries, filling inorganic particles of nanometer size with high thermal conductivity and excellent mechanical performance has become a attractive and effective method to strengthen the properties of epoxy resins and meet the higher requirements. Because micro-scale fillers have successfully been synthesized with epoxy resin, BN as a novel nano-scale filler material, which include globular BN, flake BN and fibrous BN, is now being tested to produce high performance composite structures with enhanced properties [1][2][3][4][5][6][7][8][9][10][11][12][13][14]. Recently, boron nitride (BN) based nanofillers such as BN nanoplatelets, BN nanosheets (BNNSs) and BN nanotubes (BNNTs) have attracted increased attention due to its low density, high thermal conductivity, electrical insulation, superb oxidation resistance, passivity to reactions with acids and melts, low coefficient of friction and their potential application in preparing polymer composites for thermal dissipation [15][16].…”

“…So far, there have been two approaches developed for nanofiller surface functionalization: covalent and noncovalent methods [2]. The former involves the grafting of reactive modifiers onto the surface of the nanofillers by covalent bonds, while the later is applying the physical interaction between the fillers and modifiers such as van der Walls attractions, electrostatic interactions and hydrogen bonding [17][18].…”

“…Epoxy resin is chosen as the matrix because of its extremely wide application in aerospace, automotive and electronic industries [2,19]. Zhi et al prepared a series of polymer nanocomposites with excellent thermal properties by using BNNSs and BNNTs as fillers [20][21].…”

“…The BN fillers were firstly treated with silane coupling agent and acid to introduce amine groups and hydroxy groups. The strong covalent bonding formation produced a strong interface between fillers and matrix [2].…”
