High performance benzoxazine/CNT nanohybrid network – An easy and scalable way to combine attractive properties

Novel porous nanohybrid materials with unexpected mechanical and electrical performance by pyrolysis of carbon nanotube-filled benzoxazine thermosets

“…It is noteworthy that without the help of any kind of external chemical functionalization, a relatively high content of CNTs, i.e. as high as 5 wt%, can be dispersed within P-pPDA precursors and similarly to previous works (with much lower CNT content) presented elsewhere, 9,15,16,21 the dispersion is found to be preserved during the curing process. Additionally, mechanical and thermomechanical properties were characterized to investigate and evaluate both the performance of the nanofilled resin and the effect of high CNT content.…”

“…This result appears of high interest since an optimal CNT content of 0.5 wt% was previously observed for CNT contents lower than 1 wt%. 16 In this low-CNT content range, the observed optimum was correlated to the coexistence of two mechanisms, namely interfacial constrains and free volume increase 17 but it seems that for a much higher CNT content, actually 5 wt% CNTs, the polymer chains must be still constrained and the network properties can be further reinforced.…”

An investigation on the effect of phenylboronic acid on the processibilities and thermal properties of bis-benzoxazine resins

“…Nevertheless, the improvement of the properties is limited because of the weak connection or no connection between BZ and thermosetting resin. Further improvements are achieved with the introduction of nanosize fillers (such as POSS, carbon nanotube, graphene oxide and montmorillonite) into BZs where substantial changes in thermal properties are obtained at very low loadings [15][16][17]. Unfortunately, the potential applications of such hybrid nanocomposites are hindered by manipulation difficulties due to their insolubility and poor dispersion in polymer matrix.…”

Developing Polybenzoxazine Composites Based on Various Carbon Structures

“…In 2014, Dubois and his group reported the preparation of a thermally stable CNT/PBZ composite by a simple and scalable process. A BZ monomer was synthesized using the solventless method from phenol and p ‐phenylene diamine (P‐pPDA).…”
