Additive free fabrication of polymeric composites with delayed and reduced dripping

A multilayer composite material comprising:

• a plurality of first layers, each first layer comprising a first polymer;
• and
• a plurality of second layers, each second layer comprising a second polymer, the plurality of first layers and the plurality of second layers being arranged in a repeating sequence of alternating first layers and second layers within the multilayer composite material;
• wherein
• each first layer and each second layer within the repeating sequence has a thickness in a range of about 10 nm to about 3 mm;
• the multilayer composite material has reduced dripping and a delayed first dripping time as the multilayer composite material undergoes a combustion process relative to a multilayer composite material having a single layer comprising the first polymer or the second polymer having a same thickness as a thickness of the multilayer composite material;
• the first polymer is a low-density polyethylene-based polymer and the second polymer is a polypropylene-based polymer;
• the repeating sequence of alternating first layers and second layers includes between 20 and 2560 uninterrupted alternating first layers and second layers;
• and
• the first layer and the second layer have a different thickness.
