Methods, systems, and devices for synthesis, mechanics, and direct-write additive manufacturing of cellulose nanocrystal (CNC) composites that exhibit characteristics of high-performance structural materials are provided. The methods, systems, and devices allow for formulation, processing, and bulk fabrication of highly-filled nanocomposites having high hardness and toughness. In some embodiments, a precursor that includes a nanomaterial and one or more monomers is formulated and passed through an extruder to form a physical gel. The physical gel can undergo a dual cure process that includes an initial UV cure and a subsequent thermal cure to crosslink the polymer with the CNC to form the highly-filled nanocomposite. The CNC composite can then be used in the manufacturing process. In some embodiments, the interfacial mechanics and fracture characteristics of the composite can be tuned to improve the mechanical properties of the composite.

A process of melt compounding a polyolefin formulation comprising a ethylenic-based (co)polymer, an antioxidant, and from 0.15 to 1.00 weight percent of an organic peroxide having a 1-hour half-life temperature of less than or equal to 155 degrees Celsius ( C.) and/or a 10-hour half-life temperature of less than or equal to 135 C.

A method to make a high melt strength amorphous poly alpha olefin (APAO) includes blending APAO with a free radical initiator using a residence time from 0.1 minutes to 10 minutes at a temperature range from 300 degrees Fahrenheit to 400 degrees Fahrenheit, thereby forming an intermediate. A graftable monomer may then be added to the intermediate in a ratio from 0.1:100 to 2:100 at a temperature range from 225 degrees Fahrenheit to 400 degrees Fahrenheit using a residence time from 0.1 to 20 minutes, thereby forming a functionalized APAO. A multifunctional monomer in an amount ranging from 0.1% to 5% by weight of the functionalized APAO can be added to the functionalized APAO for 0.1 to 20 minutes at 200 to 400 degrees Fahrenheit, thereby forming a cross-linkable APAO. An acid neutralizer may be added to initiate crosslinking, making a crosslinked APAO with various degrees of crosslinking as observed by the changes in the melt viscosity. An amine coupling agent may be added to the cross-linkable APAO to control crosslinking.
