Direct conversion of teflon tape into diamond, q-carbon, and graphene films

A process for coating an object comprising:

• a) applying a thin polymer film to at least a portion of the object;
• b) increasing the absorbance of an unconverted section of the thin polymer film by at least one conditioning laser pulse to produce a lasered section;
• c) melting the lasered section at a temperature of about 4000K by a conversion laser pulse;
• d) quenching the melted lasered section to form an initial quenched section comprising Q-carbon, diamond, and/or graphene;
• e) adjusting the object with the applied thin polymer film and the at least one quenched section and/or the laser positioning mechanism such that the conditioning laser pulse strikes a subsequent unconverted section of the thin polymer film;
• f) increasing the absorbance of the subsequent unconverted section of the thin polymer film by the at least one conditioning laser pulse to produce a subsequent lasered section;
• g) melting the subsequent lasered section at a temperature of about 4000K by the conversion laser pulse;
• h) quenching the melted subsequent lasered section to create a subsequent quenched section comprising Q-carbon, diamond, and/or graphene;
• and
• i) repeating steps e) through h) until a final desired portion of the thin polymer film is converted to the finished quenched section, wherein the finished quenched section comprises the initial quenched section and each of the subsequent quenched sections,
• wherein steps b) through d) and steps f) through h) occur in an environment at ambient temperature and pressure, and
• wherein the polymer film comprises a polymer selected from the group consisting of polyethylene (PE), polyvinyl chloride (PVC), polytetrafluoroethylene (PTFE), polystyrene (PS), and/or polypropylene (PP).

A process for making a three-dimensional object comprising:

• a) applying a first layer of a thin polymer film on a substrate;
• b) increasing the absorbance of an unconverted section of the thin polymer film by at least one conditioning laser pulse to produce a lasered section;
• c) melting the lasered section at a temperature of about 4000K by a conversion laser pulse;
• d) quenching the melted lasered section to form an initial quenched section comprising Q-carbon, diamond, and/or graphene;
• e) adjusting the thin polymer film and the at least one quenched section and/or the laser positioning mechanism such that the conditioning laser pulse strikes a subsequent unconverted section of the thin polymer film;

• g) melting the subsequent lasered section at a temperature of about 4000K by the at least one conversion laser pulse;
• h) quenching the melted subsequent lasered section to form a subsequent quenched section comprising Q-carbon, diamond, and/or graphene;

• j) applying a subsequent layer of the thin polymer film in a predetermined pattern to form the three-dimensional object and repeating steps b) through i);
• and
• k) repeating step j) until the three-dimensional object is completed,
• wherein steps b) through d) and steps f) through h) occur in an environment at ambient temperature and pressure, and
• wherein the polymer film comprises a polymer selected from the group consisting of polyethylene (PE), polyvinyl chloride (PVC), polytetrafluoroethylene (PTFE), polystyrene (PS), and/or polypropylene (PP).
