Polydicyclopentadiene (PDCPD) is a strong, lightweight industrial polymer with high impact resistance and good mechanical strength. Despite finding significant utility in the automotive industry, however (where it is used to manufacture body panels for heavy trucks), the broader adoption of PDCPD has been hindered by the lack of modifiable chemical functionality within the polymer, as well as a low surface energy (making it difficult to paint freshly prepared PDCPD parts, or apply adhesives) and a foul odour due to entrapped dicyclopentadiene monomer (DCPD). Wulff group PhD student Ben Godwin has solved all of these issues through the manufacture of a modified form of the DCPD monomer, which contains a single additional oxygen atom. This new-and-improved monomer, which is accessed in a single photocatalytic step from DCPD itself, has no unpleasant odour, and can by polymerized to afford a material that has improved mechanical strength relative to the traditional, unfunctionalized form of PDCPD. Even better, the presence of the oxygen atom (which is retained in the polymer product) provides an improved surface energy and should allow for improved bonding to fiber reinforcing agents, allowing PDCPD to move from low-margin automotive applications to the world of aerospace manufacturing. With the support of the Lab2Market program, Ben is looking to transition this innovative technology to the commercial sphere.

聚双环戊二烯（PDCPD）是一种强度高、重量轻的工业聚合物，具有高抗冲击性和良好的机械强度。尽管在汽车工业中发现了显著的实用性，但是（其中它用于制造重型卡车的车身面板），PDCPD的更广泛采用受到聚合物内缺乏可改性的化学官能团以及低表面能（使得难以对新制备的PDCPD部件进行涂漆或施加粘合剂）和由于夹带的双环戊二烯单体（DCPD）而产生的恶臭的阻碍。Wulff小组的博士生Ben Godwin通过制造含有单个额外氧原子的DCPD单体的改性形式解决了所有这些问题。这种新的和改进的单体，其在单个光催化步骤中从DCPD本身获得，没有令人不快的气味，并且可以通过聚合提供相对于传统的未官能化形式的PDCPD具有改进的机械强度的材料。更好的是，氧原子（保留在聚合物产品中）的存在提供了改善的表面能，并应允许改善与纤维增强剂的结合，使PDCPD从低利润的汽车应用转向航空航天制造领域。在Lab2Market计划的支持下，Ben希望将这项创新技术转移到商业领域。
