    • A method of loading nicotine into porous polymeric items consisting essentially of a polyolefin. The method comprises contacting the items with nicotine or nicotine dissolved in a carrier. The polyolefin item, preferably polyethylene or polypropylene, may be loaded with nicotine by several variations on the basic method. The items may be emplaced in a vessel with nicotine and the vessel then closed for a period of time prior to removal of said items.A preferred method of producing porous polyethylene items loaded with nicotine comprises first emplacing porous polyethylene items in a vessel. A solution comprising between about 1% nicotine and about 10% nicotine and a solvent for nicotine demonstrating an adherence for polyethylene surfaces is prepared. A quantity of this solution sufficient to contact at least a majority of the polyethylene items is added to the vessel. Excess solution is then drained from the items and the solvent evaporated from the items to produce porous polyethylene items loaded with nicotine.
    • 将尼古丁加载到基本上由聚烯烃组成的多孔聚合物中的方法。 该方法包括使物品与溶解在载体中的尼古丁或尼古丁接触。 聚烯烃项目,优选聚乙烯或聚丙烯,可以通过基本方法的若干变化来加载尼古丁。 物品可以放置在具有尼古丁的容器中,然后在移除所述物品之前关闭一段时间。 制造装载有尼古丁的多孔聚乙烯制品的优选方法包括首先在容器中放置多孔聚乙烯制品。 制备包含约1%尼古丁和约10%尼古丁的溶液和用于显示粘附于聚乙烯表面的尼古丁溶剂。 将足够接触至少大部分聚乙烯物品的该溶液的量加入到容器中。 然后从物品中排出过量溶液,并从物品中蒸发出溶剂,以生产装有尼古丁的多孔聚乙烯物品。
