Self-healing polymers are a smart material, capable of autonomic restoration of properties following damage. This WPI project team was tasked with researching the feasibility of creating a self-healing material and applying it to vehicles windshield. A healing agent, dicylcopentadiene and the Grubbs’ catalyst were encapsulated in poly(urea formaldehyde) and paraffin wax, respectively. Sample mock windshields were prepared using two pieces of borosilicate glass and a poly(vinyl butyral) interlayer containing the microcapsules and wax protected Grubbs’ catalyst. These samples were tested for optical properties and then cracked. Following a healing period of seven days, the samples were tested again for optical properties as well as mechanical properties
