POLYHEXAHYDROTRIAZINE DIELECTRICS

摘要

Low dielectric constant (low-k) polyhemiaminal (PHA) and polyhexahydrotriazine (PHT) materials with cyclic aliphatic ring structures are described. The materials are formed by a method that includes heating a mixture comprising amines and paraformaldehyde. The reaction mixtures may be used to form low-k PHT prepregs, composites and dielectrics used in integrated circuits.
