We have studied the percolation of (a) linear segments of size k; (b) k-mers of different structures and forms deposited on lattices with different symmetries. In the latter case, site and bond percolation have been examined. The analysis of the results obtained by using finite size scaling theory is performed in order to test the universality of the problem by determining the numerical values of the critical exponents of the phase transition involved in the problem. We have also determined that the percolation threshold exhibits a exponentially decreasing function when it is plotted as a function of the k-mer size. The characteristic parameters of that function are dependent not only on the form and structure of the k-mers but also of the properties of the lattice where they are deposited.
