A high-strength network structured nano-carrier material and a preparation method and application thereof. A nano-cellulose solution and graphene are mixed and ultrasonication is performed in an ultrasonic pulverizer to obtain a nano-cellulose/graphene suspension. The suspension with a phenolic resin adhesive is mixed and stirred to obtain a nano-cellulose/graphene/phenolic resin suspension. The nano-cellulose/graphene/phenolic resin suspension is injected into a mold. The mold is placed in a freeze dryer for freezing and vacuum dried in two stages to obtain a nano-cellulose/graphene/phenolic resin aerogel. The aerogel is preheated and cured in a muffle furnace, then subjected to a high-temperature thermal decomposition treatment in a tube furnace to obtain a nano-carrier material having a high-strength network structure. The preparation method is simple and convenient, low in cost, environmentally friendly and green. The obtained carrier material has a good water resistance and a high mechanical property, and can carry more active substances.

A method for using a modifier that includes mixing 0.5 parts by mass or more but 70 parts by mass or less of the modifier per 100 parts by mass of a first polyolefin resin. The modifier is composed of a continuous phase (A) containing a second polyolefin resin, and a dispersed phase (B) dispersed in the continuous phase (A) and containing a polyamide resin and a modified elastomer. The dispersed phase (B) is composed of a melt-kneaded product of the polyamide resin and the modified elastomer having a reactive group that reacts with the polyamide resin. When a total of the continuous phase (A) and the dispersed phase (B) is 100% by mass, a content of the dispersed phase (B) is 80% by mass or less.

Methods for recycling thermoset polymers, particularly by changing them into dynamic networks with the use of an appropriate catalyst solution which transforms the thermoset polymer into a vitrimer-like composition. The methods include the step of swelling a crosslinked thermoset polymer in a solution including a catalyst, whereby the catalyst diffuses into the thermoset polymer, in particular into the thermoset network. Upon removal of the liquid portion of the solution, such as solvent, the catalyst facilitates the occurrence of exchange reactions at elevated temperatures, rendering the system a dynamic network. The vitrimerized composition having the thermoset polymer and catalyst is recyclable and processable and thus suitable for many end uses.

Embodiments of the present invention relate to methods for preparing high optical density solutions of nanoparticle, such as nanoplates, silver nanoplates or silver platelet nanoparticles, and to the solutions and substrates prepared by the methods. The process can include the addition of stabilizing agents (e.g., chemical or biological agents bound or otherwise linked to the nanoparticle surface) that stabilize the nanoparticle before, during, and/or after concentration, thereby allowing for the production of a stable, high optical density solution of silver nanoplates. The process can also include increasing the concentration of silver nanoplates within the solution, and thus increasing the solution optical density.
