The present disclosure pertains to the technical field of resin composite materials and more particularly relates to resin compositions and articles made therefrom, including a resin film, a prepreg, a laminate or a printed circuit board, wherein the resin composition comprises a phosphorus-containing flame retardant of Formula (I) and a prepolymerized resin prepared at least from a divinylbenzene compound, an allyl resin and an acrylate resin. The resin compositions may be further used to make a resin film, a prepreg, a laminate or a printed circuit board, which has the properties of absence of branch-like pattern on laminate surface, high glass transition temperature, low ratio of thermal expansion, and high copper foil peeling strength.

The present disclosure relates to a process for preparing coated cellulose nanocrystals (CNCs) and relates as well to coated cellulose nanocrystals (CNCs) obtainable by the process described herein. These new CNC hybrid nanomaterials are expected to be useful, for example, for the conjugation and electrostatic complexation with various functional moieties such as free metal ions, carboxylic acids, and epoxy and aldehyde derivatives. The disclosure further relates to a method to fabricate N-doped carbon nanomaterial from the coated CNCs.

In one or more embodiments, the present invention provides a heat dissipating polymer materials (and films thereof) that utilize supramolecular chemistry. In various embodiments, these materials comprise networks of hydrogen bonded supramolecular crystals, self-assembled into aligned 2-D layered sheet structures that are distributed throughout a polymer matrix. In some of these embodiments, the heat dissipating polymer materials are prepared by in-situ co-precipitation of melamine and cyanuric acid in a PVA polymer resulting in homogenous distribution of MC crystals and the eventual formation of a network of hydrogen bonded melamine-cyanurate (MC) 2-D layered sheet structures throughout the PVA polymer.

A method for providing a primer coating on an automotive body component is provided. The method includes mixing a first part comprising polyester and melamine with a second part comprising an unblocked acid catalyst to form a mixed composition; applying the mixed composition to the automotive body component; and curing the mixed composition on the automotive body component at a temperature of less than about 120 C. (250 F.), such as from about 87 C. (190 F.) to about 110 C. (230 F.).
