Abstract
Certain embodiments of the invention described herein comprise a composition of matter, and method for preparing the same, which provide the benefits of pre-reaction molecular configuration favoring high liquidity properties, and post-reaction configuration that favors mechanical strength, stiffness, and properties associated with high viscous and/or solid-state materials. In some embodiments, the composition of matter can comprise relaxing photo-isomerizable fragments, of which a fraction can be transformed from trans to cis configurations upon exposure to a photon source. In some embodiments, the composition of matter further comprises thermally reactive fragments, of which can enable thermal solidification of a mixture upon exposure to elevated temperatures. In some embodiments, a composition of matter can be combined with reinforcing additives to form a prepreg combination.
