Abstract
Fibrous materials made from multiple populations of fibers, and compositions related to preparing such, are disclosed. In some instances, fiber populations can have different native surfaces, in which at least one of the populations can be surface modified, for example by the use of a polycation (e.g., a polyamine), secondary polymers, complementary polymers, and/or other agents. These populations can be combined to form a fibrous composition, where the surface treatments can enhance properties of the end product. Populations of fibers can also have other physically varying characteristics (e.g., shapes and sizes). Such compositions can be utilized in a variety of applications such as paper products, filters, fire-retardant fibrous products, protein adsorbing fibrous materials, and fibrous sheets having conducting properties. Methods of preparing portions or the entirety of such fibrous materials are also disclosed.
