- PDKs are an interesting type of plastic that differ from conventional plastics in that we completely replaced the static covalent bonds that typically comprise... that make up the polymer backbone and we replaced them with dynamic covalent bonds that allow you to do a number of new things.
PDK 塑膠很有趣，和傳統塑膠的不同在於，將原本用來組成聚合體主結構的靜態共價鍵替換成動態共價鍵，就能達成許多新用途。
