Method to disperse nano-cellulose in organic polymer precursors

This invention concerns a novel method to produce thermosets such as epoxies and polyurethanes comprising nano-cellulose. The method comprises contacting primarily water-bourne dispersed nano-cellulose with liquid thermoset precursors, specifically epoxy or amine in the case of epoxies, or glycols or similar in the case of polyurethanes. Nano-cellulose transfers to the organic phase, and water is removed at temperatures below 100° C. Thereafter the organic phase comprising nano-cellulose can be mixed with the reactive counterpart to yield nano-composites with improved properties. The products can be used for composite articles, coatings, adhesives, sealants, and other end-uses. Preferred embodiments are described in detail.

ADHESIVE FOR SURGICAL STAPLE LINE REINFORCEMENT

The present disclosure provides medical products including an adhesive containing a carboxyalkyl cellulose and sorbitol. Such medical products can find use as a bolster material for use in conjunction with a surgical fastening device such as a stapler. Such adhesives may include advantageous properties such as the ability to retain tack while stored under a peelable cover. Related methods of manufacture and use are also described.
