Driven by the need to make high temperature thermoplastic polymers more processable and expand the range of applications, this study reports on the properties of a novel PAEK material developed by Victrex (Thornton Cleveleys, UK) which is capable of undergoing crosslinking or crystallisation, two competing processes that can be adapted via specific processing temperature and time conditions. The uniqueness of this PAEK material resides in its manufacturing approach, where the crosslinkers are incorporated during the polymerisation process, and its distinct properties, including a controllable viscosity that can be tuned from low to high to allow its application in complex manufacturing processes, such as thermoplastic carbon fibre manufacturing.
出于使高温热塑性聚合物更易于加工并扩大应用范围的需求，本研究报告了威格斯公司（英国桑顿克里夫利）开发的一种新型聚芳醚酮（PAEK）材料的性能。该材料能够进行交联或结晶，这两个相互竞争的过程可通过特定的加工温度和时间条件进行调整。这种PAEK材料的独特之处在于其制造方法，即在聚合过程中加入交联剂，以及其独特的性能，包括可控制的粘度，可从低到高进行调节，以使其能够应用于复杂的制造工艺，如热塑性碳纤维制造。
