The fabrication of lignin/poly(amide-imide) composite aerogels using an environmentally friendly freeze drying process, and the use of these aerogels in oil absorption processes will be discussed. Lignin is one of the main components of trees, and it is a waste product in the paper industry; most of this lignin is burned off as a fuel source. It has been previously reported that poly(amide-imide) aerogels are excellent oil absorbing materials. Cost is a major disadvantage of these materials, however, so incorporation of lignin as a low cost diluent could represent an important step towards their commercialization. In addition to the use of lignin/poly(amide-imide) aerogels as oil absorption materials, the mechanical properties of these materials will be discussed.
