Abstract

A simple and easy process has been developed to dope phosphorus functionalities into the surface area of pigment. Further, exfoliated graphite-functionalized pigment (EGFP) was synthesized using the one-pot facile method by treating functionalized pigment (FP)to the graphite. As-made EGFP solution coated on cloth exhibits excellent flame retardation properties. The EGFP-coated cloth did not emit smoke at the beginning without catching fire for more than 760 s and maintained its initial shape with negligible shrinkage. In contrast, the blank cloth caught fire within 5 s and completely burned out within 15 s, leaving trace amounts of black residue. The Limiting Oxygen Index value (LOI) of EGFP is 48 %. The simple technique of direct introduction of phosphorus into the pigment surface to produce phosphorus-doped carbon platelets may be a general approach for many practical applications, including flame retardation.

通过级联反应合成的酚嗪缀合碳板可用作棉织物的防火罩

在颜料的表面区域掺入磷官能团的工艺简单易行。通过将功能化颜料（FP）处理到石墨上，利用一锅简便方法合成了剥离石墨功能化颜料（EGFP）。制成的 EGFP 溶液涂覆在布料上，具有优异的阻燃性能。涂有 EGFP 的布在开始燃烧时不冒烟，燃烧时间超过 760 秒，并能保持初始形状，收缩率几乎可以忽略不计。相比之下，坯布在 5 秒内起火，15 秒内完全燃烧殆尽，并留下微量黑色残留物。EGFP 的极限氧指数（LOI）为 48%。将磷直接引入颜料表面以生产掺磷碳平板的简单技术可能是许多实际应用（包括阻燃）的通用方法。

期刊介绍： The Journal of Physics and Chemistry of Solids is a well-established international medium for publication of archival research in condensed matter and materials sciences. Areas of interest broadly include experimental and theoretical research on electronic, magnetic, spectroscopic and structural properties as well as the statistical mechanics and thermodynamics of materials. The focus is on gaining physical and chemical insight into the properties and potential applications of condensed matter systems. Within the broad scope of the journal, beyond regular contributions, the editors have identified submissions in the following areas of physics and chemistry of solids to be of special current interest to the journal: Low-dimensional systems Exotic states of quantum electron matter including topological phases Energy conversion and storage Interfaces, nanoparticles and catalysts.
