ANY written, music or video material that you can see (or hear) can be copied. The best that you can manage is to make it a tad less convenient to do so. If you could make copying impossible, the media industry alone would reward you beyond the wildest dreams of Croesus.
You could create a PDF with protection against copying or printing - e.g. see
